How to choose a car amplifier | Crutchfield

Car amplifiers do a lot more than just make your music play loud - they make all music sound better. But with so many to choose from, which one is right for your car?

9:20 Outro
A lot of people think of loudness when they think of amplifiers, but that's just one benefit. An amplifier will make your music sound cleaner and more defined even at lower volumes.
Amplifiers can really bring the best qualities of aftermarket speakers forward. Aftermarket speakers, unlike factory speakers, are designed to handle more power, play cleaner, and reveal more detail than factory speakers, which are designed mainly to a certain (low) price point.
Subwoofers need an amp to move enough air to play the low frequencies. Some subs have the amp built in, called powered subwoofers, while your component subs use a separate amplifier.
So which type do you need? 2-channel? 4-channel? 5 or 6 channel? More channels? How much power? Are there certain features you want or need? Our expert walks you through it in this video.

[@nickrose8733]

Thanks. That was great. I appreciated that your power recommendation for amps was conservative as many people think they need 1000W amps. Also, amps should be at or below the speaker ratings. So many people think that you need amps rated higher than the continuous RMS rating of the speakers.

[@Xx_xxx_xX185]

Thats not true you actually want to have more rms power from the amp than the speakers because then you dont need to push the amp that hard to get the power needed but if you have amp with lower rms power you are more likely to push it too hard and break your amp or speakers

[@josequilez5449]

Nick your gonna blow amps by overworking them to push your speakers. These guys sell audio equipment. That's why they give the limited explanation they do. So you can buy more from them with the feeling that it's spent well instead of actually teaching you the truth.

[@noorazmi2329]

choose based on your financial capability. other than that, look at your car specifications like electrical system power (you might want to add additional battery and after that can consider power capacitors), so your audio system doesn't short your car electrical capacity even at max volume. you also better use 3x more powerful amp than your speaker RMS because most amplifier will start to produce more than 1% THD after more than 1/3 of total amp power. this is to ensure you can maintain your low distortion listening experience and not to be worried about harsher sound and even clipping your amplifier, as long as you set the small volume knob at 1/3. keep calibrate the amp according to the head unit spec so you can be sure it doesn't go more than the power threshold you've set. if the overall volume is too low, you can always compromise your sq for bigger sound but at higher THD anytime. but make sure the speaker RMS is matching if not more so to be on the safe side.

Question: I recently picked up a SD 1200.4 thinking it was a 4 ohm version but found out it was the 2 ohm version. this DRASTICALLY changes the power per channel at each ohm variance. the speakers I want to push are 100 RMS but 250 PEAK. I can do 138 per channel running them each on their own channel (running 4 speakers all the same make/model)... one place tells me to run bridged and parallel. but if they exchange my amp for the 4 ohm version I would have 198 per channel at 4 ohm. I get others saying the current amp wont be enough, and yet others saying the current one will be to much in the video it talks about speakers having "Max RMS" and I get the 75-100% thing. but with the RMS having one rating and then my "peak" being a very different number... which rating do I use? and what wiring method would be best. I can exchange straight across for the other amp. should I get the other amp or stay with what I have and wire it in a specific way?

P16 2 way in the rear doors all connected to a factory stereo with a 5 channel amp in Mitsubishi Outlander. Amp R2750X5 that is 750 watt rms. and the sub is a sealed enclosure of 200 rms rockford 12". Am not at all satisfied with the quality of the system and don't want to get it done from the same place again. I am lacking bass and the clerity of sound. Also I do not have much room for sub becuase its behind the third row. But I want Some serious bass to shake the car with clarity in speakers. WHat should I be upgrading? and what specs should I look for while upgrading?

[@crutchfield]

If you can change to a ported subwoofer box setup, that will help. Also, find one that presents a 2 ohm load to that amp to get all the power it can give for a subwoofer. The clarity of the other speakers may be able to be increased depending on what was used to help get the audio from the stock system to the new amp. I recommend contacting an advisor to discuss these specifics and ideal changes to get a personal recommendation on gear to help with your goals.

Hi Crutchfield. A few questions for you: 1) I currently have one X-12 V.2 D4 - Sundown Audio 12" 1500W RMS DVC 4-Ohm X V.2 Series Subwoofer in a custom ported enclosure tuned to 32 Hz. What monoblock amplifier do I need to provide sufficient quality power? 2) I eventually plan on adding a second Sundown Audio subwoofer for a total of two subwoofers, but that won't be for about 7-8 months from now. What monoblock amp do you recommend to power the 2 subwoofers previously mentioned?

[@crutchfield]

Based on those specifications, we only offer one amp that can power two: www.crutchfield.com/I-rYTVc227/p_57525001CP/item.html The single sub setup can be powered with an amp that gives it 70% of the top RMS power. That's the minimum we recommend for good performance. This means 1075 watts RMS is the minimum making this amp able to sufficiently power one sub: www.crutchfield.com/I-rYTVc227/p_301HCP1DK/item.html

[@philipallen4230]

Great video, really helpful. I'm planning a car audio build and I'm looking at an Alpine 5 channel amp to power four 40 watt 4ohm speakers and two 200watt 2ohm DVC subwoofers. The amp has 4 channels with 40watts at 4 ohms and 1 channel with 300watts at 2ohms. If I run the subs in parallel/serial the impedance will match the amp's 2ohms but the amp would only be supplying 75% of the subs required 400 watts. I was told by a local shop that underpowering the subs like this will damage the subs and overheat the amp. However, in this video, you said, "you should strive to be within 75% to 100% of the subwoofer power". Do you think this setup would be OK? I realise what I'm looking at would be at the lower limit but I'm not looking for a loud system, just better quality. Thanks in advance.

[@crutchfield]

this would work just fine! The problems can arise if you A) turn your gains up ( Gain is not a volume knob) and B) run your amp at full blast for a long time. this can stress out the amp over time. Now, 75% of the RMS power should be ok for your subs, any lower and you could risk there being a loss of control of the cones which can lead to flexing, distortion, and stress on both the cones and the coils.

Great video. I have a little different sce ario where my speakers are 2 ohm 75Wrms and the Head Unit is 25W per channel at 4 ohm. Is this putting at risk my head unit? If that is the case can I use a 4 ohm 600 amp to cover the need for power?? Thank you so much for your time!

[@crutchfield]

Most head units are not able to support 2 ohm speakers. If the head unit can support 2 ohms, the owner's manual will list it. If your head unit is one that cannot support 2 ohms, that is likely to put the head unit at risk. We need to check the amp's watts RMS per channel at 2 ohms. The amp should output no more than 75 watts RMS at 2 ohms. If it does not exceed the 75 watts RMS at 2 ohms, then it will work with the speakers

[@Vayves]

Hi! I replaced the all stock Boston speakers in my 2011 Chrysler 200s Convertible for kicker CS series speakers, because the previous owner abused the stock system and it sounded like it was on its last leg. And now, they play quite a bit lower on volume, I assume because they are 4ohm vs 2ohm, and the door speakers play only bass, as in the tweeters and mid-range aren't active at all, because the stock system used the door speakers as subs pretty much. And my question is, how do I choose an amp for these speakers? Because most of the amps are for example x4 channels at 90watts, while in my car the dash speakers are 35w RMS, the door speakers are 150w RMS, and the rear seat speakers are 100w rms, and I have no idea what amp to choose with this setup. Any tips would be greatly appreciated!

[@crutchfield]

More power is a big plus for the Kicker CS line. To use an amp for everything, your best bet is to move to beefier dash speakers as well. Our advisors can help you choose both. Please reach out to them here: www.crutchfield.com/I-rYTVc921/support/ContactUs.aspx

Hey there. I have a 2 way ground zero uranium kit that says it's 130wrms for each side and 210wrms maximum for each side. Do you think a CTX 1000.4 RE audio amplifier will be enough? This amplifier on the manufacturer's website says to deliver 100wrms x 4 - 4ohms 14.4v but in the manual of the amp itself, it declares 80wrms x 4 - 4ohms 14.4v. Anyway, would it be enough or would it lack power?

We are not familiar with those speakers, but we do know that typically when a speaker lists a watts RMS range, the first number if the minimum amount of power they should get to give the sound they have been designed to produce and the second number is the one that should not be exceeded. Also, the speaker can typically still work with less power; just not producing the sound they should

[@cnovalles73]

What about some of the powered subs on your website as opposed to a sub and separate amp?

[@crutchfield]

Those are already matched in terms of amp power and the subwoofer. Its still a good idea to follow the recommendations given for the power needed to match different versions of systems in a vehicle given in the "how to pick out a mono amp" section of this video. We also have advisors that can discuss your system and goals for the sound to give you a personal recommendation on one. Here's how to reach us for this help: www.crutchfield.com/I-rYTVc227/support/ContactUs.aspx

If you can bridge that Kenwood amp to use 2 front speakers and a sub, how does that work if the sub needs to have significantly more wattage to keep up with the front speakers?

[@crutchfield]

Hi there! We recommend pairing the amplifier wattage output to about 70-100% of the speaker/sub RMS power handling. Some amps, when bridged, can satisfy the speakers as well as the sub, but if you have a sub that needs more power, then a separate mono amp may be in order.

What is the best amplifier to get to power my TRF LWT693 (80w rms) speakers and KENWOOD KSC-W1200B(300w rms) subwoofer from the Pioneer MVH-S420BT radio?? I’m lost

[@crutchfield]

We'll be glad to recommend an amp for power. How many of the speakers do you have? How many subs?

Do I need an amp if my aftermarket headunit has 4 x 55W of power for speakers that have an RMS power of 80W?

[@crutchfield]

An amplifier is always beneficial, but not always necessary. Depending on if your head unit is supplying 55 watts RMS, or if that is a peak power rating, would help us be more precise with our information. It would also help to know how sensitive your speakers are. Feel free to connect with us online or by phone, for assistance in real time. www.crutchfield.com/I-rYTVc164/contact

Hey I really hope you see this ice currently got 2 150w 4omb audio pipe ts-cvr6 woofer speakers and an old 360w sub woofer speaker that I had from an old stereo. Now what I want to do is combine them and hook them up to my pc but I'm not sure what to look for in my amplifier

[@crutchfield]

We will be happy to help and have a few questions so we can make sure you get an amp that will work. What is the brand/model of the older subwoofer? We need to know some of its specifications to endure a proper power match to the amp. Also, does your computer have the ability to output only bass audio through any of its ports? If it does, what type of port will that bass be output on?

[@loganharrington5848]

Thanks for the video but could I power 4 door speakers and 2 tweeters with a 4 channel amp?

[@crutchfield]

It is possible that this can work and will depend on the gear being used. Do you already have the speakers, tweeters, and/or amp? If you do, what are the brands and models of the gear you have now?

[@dee1323]

Would I need to get a higher channel amplifier if I’m using component speakers rather than ‘all in one’ type speakers?

[@crutchfield]

Hi Damon! The answer to that question would depend on the speakers you were planning to use. Using an amplifier to power component speakers is not always necessary, but it is the most ideal solution. An outboard amp will be able to power your speakers with greater efficiency, and improve your sound quality of your upgraded speakers. We will be happy to go over any speakers you may be interested in, and provide you with more detailed advice based on your particular application. www.crutchfield.com/I-rYTVc164/contact

Hi JR, you video was helpful and interesting. I have a 1954 Chevy truck, this car has never had a radio or stereo. I have a CD player that I would like to install with 2 Infinity 6532EX 6.5inch 165 watts peak speakers. Should I get an amp, would you recommend getting tweeters or a larger woofer ? any other suggestions ? Thank You PS My truck is still 6 Volt, I currently have a small 6v to 12V converter for a backup camera. What size power converter would I need to run this stereo system ?

[@crutchfield]

An amp that is matched to the speakers never hurts the sound! But at this time, it is unknown if an amp is needed or should be installed to meet your goals. Infinity Reference speakers are super efficient and can give a lot of sound when being powered by a radio. For some, that is enough. You could try that first and then add an amp if you want more. As for adding a tweeter, that is not needed. Those speakers come with a tweeter built in. If the speaker will be installed into a lower location in the pickup, then you might consider changing to the REF-6530CX speakers as those will keep the sound balanced while also providing a separate tweeter that can be mounted higher in the pickup and help with the overall clarity of the audio. These speakers can be found here: www.crutchfield.com/I-rYALc227/p_108R6530CM/item.html

[@crutchfield]

Hi Denzel, great choice on the speakers! The Pioneer GM-DX874 is a perfect amp match here: www.crutchfield.com/I-rYALc921/p_130GMDX874/Pioneer-GM-DX874.html?tp=35782

Hi...i bought 2 pairs of jbl gto609c component speakers and looking for an 4 channel amplifier which would be perfect fit for them, can you suggest any amplifiers which would be perfect fit for them. please recommend jbl amplifiers too. confusing thing is these speakers are 3 ohms so can i use 4 ohmn amplifier?

[@crutchfield]

It is best to make sure the amp can support a 2 ohm load as that means it will work with 3 ohm speakers like those JBL models. There are a lot of amps that can be used to power these speakers including the JBL brand. Here's the ones that will work very well with those speakers: www.crutchfield.com/I-rYTVc227/g_347050/4-channel-Amps.html?tp=35782#&nvpair=FFRMS_Power@@Channel|[rank2]%2061%20-%2080%20watts&nvpair=YCMinimum_Impedance_Unbridged|2

Question: I have an aftermarket head unit with 180 watts RMS (45 watts x 4 speakers 4Ω) and I am considering adding an amplifier to power the Alpine RS69.2 6x9" speakers in the rear of my classic car which have 100 watts RMS (300 watts peak power). For this setup, should I be looking at 2-channel amps with 100 watts RMS x 2?

[@crutchfield]

100x2 RMS at 4-ohms will be ideal.

[@mwheatley63]

So if I'm gonna run (2)110 watt rms bullet tweeters, and (4) 6½ midrange 110 watt rms door speakers, do I need a 6 channel amp or can I use a 4 channel and wire two speakers in parallel to one channel( X 2) for a 2ohm load and 2 channels to a 4 ohm load? I'm just not sure if you can run (2) channels @ 2 ohms and (2) channels @ 4 ohms?I am looking at the Pioneer Ts-M650pro and Ts-B350pro

[@crutchfield]

That could definitely work. Other options might be available too. Is this being installed into a vehicle? If it is, what is the year, make, and model of it? Is this being connected to an aftermarket radio? It is being used with an external audio processor?

[@alhamedi66]

Amazing since knowledge thank for sharing your experience. If there are Practical example on board it will be more easy for beginners. Question 👇 The audio frequency output from the radio in low level or high level. Amplifier must receive low level frequency from radio unit or no matter. If the head unit high level output must reduce it before send it to amplifier. Waiting your reply ASAP Best regards

[@crutchfield]

The answers to these questions will vary depending on the amp being installed and the radio its being connected to. We can help; just need to know more information. Are you keeping the factory radio installed in your vehicle? If you are, what is the year, make, and model of the vehicle? If you are replacing the radio, which radio will be installed?

We have not been able to research any of the 2003 Mercedes SL Class vehicles and as such don't have any gear to help replace the radio in them. I wish I had different news for you there. We have researched other models, like the C class. We do not have an adapter that allows a new radio to work with the stock Bose amp and recommend that our customers bypass it and install new speakers that can work with the new radio or a new amp.

I'm new to subwoofer set ups and I have JL audio speakers in the doors and just got a factory subwoofer for my car. Its a chevy hhr and I don't know if I need a four channel amp with a mono amp for the sub or not?

[@crutchfield]

For most vehicle setups, you can go with a 5-channel amp that provides 4 channels for the speakers and a 5th channel for the sub. You also have the option of using a separate 4-channel amp and a mono amp for the sub. That may change depending on the number of speakers you need to power, but this is typical for many setups. Sometimes the choice comes down to personal preference and price, and sometimes the wattage match is easier with one or the other. We can help narrow the options! What is the year on that HHR? What JL Audio speakers are you using, and do you have any information on that subwoofer?

[@crutchfield]

Based on the measurements of the available space behind the seats, there is room for either sized subwoofer in a sealed box. You may have an easier time finding premade 10" sub boxes to fit. If you are building your own box, then we recommend looking for shallow subwoofers.

I am replacing all 4 doors speakers with (kicker-6 3/4 with 240 watts peak) and i'am trying to install 2 6x9 Rockford fosgate 3-way Coaxel single (4 OHM) 130 watts peak (65W RMS) on the rear deck...mind you the vehicle when i bought it didn't come with rear speakers or(wiring) and no holes were made on the panel only on the main base of the vehicle.So i'am trying to figure what type of amp should i get to support these speakers along in the future if i wanted to add a sub also. Thank you in advance for any help.

[@crutchfield]

It sounds like you're going to be running a total of 6 speakers. Do you know what model Kicker and Rockford Fosgate speakers those are? We want to match the speakers to the amp based on the rms power and not the peak power. Also are you using your stock radio or an aftermarket radio with this set up?

[@estianhattingh3624]

This is awesome But I have a question? If you need about 400 watts for your subs. This might sound like a rookie question because I am a rookie... Can you use 2 subs 200 watts each or doesn't it work like that? So is 2 * 200 watt equal to 1*400watt?

[@crutchfield]

You are on the right track in knowing that you should make sure the amp can output the total RMS watts handled by all the subs when added together. And then make sure the amp outputs that power at the combined ohm for the subs when they are wired together. We have an article that can help explain this more in-depth: www.crutchfield.com/I-rYTVc227/learn/how-to-match-subwoofers-and-amplifiers.html And we have advisors that you can call to get a personal recommendation on an amp to power your two subwoofers. Here's how to reach us for this help: www.crutchfield.com/I-rYTVc227/support/ContactUs.aspx

[@alek385]

I would suggest 1* 400w sub. This sub will be able to handle a lot more than those 2* 200w. If you come across a more powerful amp, good quality subs will be able to handle even the double the power or higher. 200w subwoofer tens to bottom out much quicker than 400w.

Take the watts rms and the resitance of the subs voice coil if dvc it can be wired double and half total resistance of a single voice coil, find an amp with the matching rms power at specified resistance, try match peak of sub to peak power of amp to not overly mismatch, (rms is the importantbpower here though) and low thd and high s/n (snr) because s/n is signal to noise ratio a!d thd is totao harmonic distortion, then wire them propperly :) make sure the amp physically fits where you want to install it
