The Top 10 BIGGEST MISTAKES in Car Audio. How to do it right!

[@Skillerj7]

This man is talking 3,5,10k watts and I’m over here stressing if my alternator and battery can handle 700-1000w

[@Kyle-j7k2u]

Usually an extra battery and upgraded one up front is fine for something

[@derekgardin1512]

Most stock electrical will be fine under 1500 watts total. I've ran plenty of systems 900-1500 total (400 RMS on doors and 500-1000RMS on sub) and have been fine. Done it on many different vehicles. As long as you have a decent battery and don't play it when the car isn't running you'll be fine. My stereo would kill my battery inside 2 songs if the car was off.

[@Kyle-j7k2u]

If you're running a true 1000 watt rms like a JL 1000/1 you will need a small secondary battery and a big 3 won't hurt. You will most likely notice the headlights dimming

[@TheRealTyla]

So im guessing running 2400 watts on stock electrical is a thumbs down​@@derekgardin1512

​@@derekgardin1512what do you think 1800w would do to stock

Right i been doing this for years bought to run a passive eq to control the sounds got a 92 road master 4 12s in the trunk so im going to to ground it right, dam lol i been taking short cuts , but I learned my self thanks peace and much love

[@thinshadow6669]

Great advice! You should mention some companies such as rockville tend to use "rms" incorrectly. At least they include the "cea" rating, which is the actual "rms" in this case. And often companies don't include the rms and only the peak power handling hoping that you'll come to the conclusion that it's half of what the peak is. Don't take the bait! If they can't tell you the rms you should try to stay away from them.

[@NextLevelCarAudio]

Thanks for the input.... Absolutely right!

[@woodandtable]

I get it. Using the gain to compensate for under power is not a good thing. Leaving the gain alone, or setting properly on a system with a large wattage sub paired with a smaller RMS amp channel.

[@TheSaint106]

I always overkill when it comes to my systems.....and the bolt that goes thru ur seat belt latch goes straight into the frame so it is a good ground but u need to do a little bit of wire brushing....but it is only good for 5000 or less watts any more then I would pry just go under the car and go straight to the frame

[@davntelisha19]

I have a 8k taramp 1ohm then I have 2 star audio 1 ohm 3000 watts max and I also change my alternator to a 370 but when my bass hits it clips goes into protection mode I turn my gain down but sometimes it clips only if I turn it up a little to much I have 3 battery’s too one yellow top and the other ones are ds18 audio battery’s there pretty big battery’s but my bass amp clips from time to time when bass hits hard i have 2 grounds and 2 o gauge wires going threw it I used a splitter at the power and ground to have to grounds and 2 red wire at o gauge but it clips from time to time I’m wondering maybe my taramp 8k bass needs more voltage is the only thing I can think off your thoughts my voice side I have a taramp 5k for my 4 10 but that side never clips

[@do_italldayeveryday820]

Ok for speakers ofc wire is the way and for the rca what will be a good reliable way to go?

[@NextLevelCarAudio]

Make sure they get shielded! Double or triple shielded would be best to eliminate potential signal interference! Also nylon jacketed is a nice extra layer of protection.

[@JakeRawbs]

Great Video Man!!! Very Knowledgeable!

[@KS-ox1kx]

Is fusing solely based on wire size or wattage of your system? Thanks for the info. Building my first with purpose and knowledge!

[@NextLevelCarAudio]

You fuse the wire to protect the wire. I run zero gauge and do 350 amp fuses

[@Highrollinhunter]

I'm into bass guitars well I made mistakes in the past with my solid state preamps right now I got a new amp I'm not cranking the gain or I'm going to blow a fan like I did with my old amp. It's the same with car audio that why I'm so careful installing aftermarket speakers and preamps.

[@pyder192002]

So I have a question, I have a 1k watt pioneer amp and 12” kicker compRT how can I make those work appropriately

[@NextLevelCarAudio]

Biggest thing is making sure Gain is set properly. Especially if amp is going to be overpowering sub. LPF set to around 100.

[@HappyDaClown187]

Hi I love the video I'm adding a simple 12 with a matching skar audio setup to my daily driver should I worry about voltage drop with a stock setup wiring wise?

[@NextLevelCarAudio]

Sorry for the late reply, this comment was buried and just got to it. If your under 1000 watts I would not worry about it one bit. Under 2000 probably big-3 and upgraded under hood battery

[@turbolarsen6794]

i haw ground loop in my car but i know how to fix that, but my ground zero amplifier makes a constant wistle sound and it hurts my ears. how do i fix that ?

[@NextLevelCarAudio]

Does it change sound with rpm?

[@stanmondzelewski9253]

Does bridging a 2channel amp cut the speaker impedance in half? I was told this many years ago. Like if i bridge my amp to 1 4ohm svc sub. Does the amp see it as a 2ohm load or 4ohm load?

[@NextLevelCarAudio]

That’s correct. When bridging a 2 channel amp the specs almost always call for a 4ohm minimum load. Because It will be giving the 4ohm speaker 2ohm power so to speak

[@maccook5230]

Do you think it’s ok to run a a different size power and ground wire for my amp for example 10 gauge ground and 8 gauge power?

[@NextLevelCarAudio]

They should always be the same! The only exception if your in a pinch would be if the ground wire was super short. Like 1 foot long to compensate for the lesser gauge. But would eventually replace with same gauge.

[@shaunjay6040]

Is it true that in most cases, you’ll never see the rated rms nor max power of your amplifier on music?

[@NextLevelCarAudio]

That’s true. Rise is a bitch. That’s why always better to overpower so you have headroom

[@nathan5270]

Do i need a fuse before the main then after the battery to the amp?😅

[@nathan5270]

Meaning a fuse up front and 2 fuses in the back ?

[@NuriBass69]

​@@nathan5270 Yes. If you have a positive wire going from a power source you have to put a fuse on it. No matter if it goes towards another battery, to a volt meter or to an amp ALWAYS put a fuse in the right size on it.

[@donellis5005]

Also how can you make sure your wiring up your door speakers in the right polarity?

[@NextLevelCarAudio]

if the speakers polarity are not labeled from the factory (some are some are not) then you need to do your research. You can find master sheets for some vehicles that diagram out all the wiring online for free. There are wiring diagrams for every vehicle that are available to installers at car audio shops. get friendly with one and they can print it our for your specific vehicle ;)

Hey man awesome channel, definitely gonna be one of the best car audio channels on YT. Quick question currently running 3 VXF 12s on a skar 3500.1 2ohm duel voice coils and currently purchased another 3500.1 to strap together so I'll be at a 2 ohm minimum at the amps. I have a very healthy power supply and my sub wiring options are 1.3 ohm or 3 ohm. Kills me thinking about losing power if I go the 3 ohm option. Would it be to risky to wire to the 1.3 with box rise?

[@NextLevelCarAudio]

You should be more than okay... just set gain a little more “conservative” than you would. Typically to not overwork your amps. With rise, you will be well over 2 probably closer to 3. So yeah buddy, that’s what I’d do!

So I'm semi new to this. I have an amp that is 700rms, it preforms at 700 watts at 1 ohm. I ordered a kicker 10 inch q series that when wired parallel comes in at 1 ohm. The rms rating for the speaker is 700 watts. So if I parallel this speaker at 1 ohm and the amp is 700 at 1 ohm I should be perfect correct? This stuff can be confusing.

If you have A strong under hood battery and big 3 you should be good. Tho most HO alts put out only half power at idle. So if lights dimming with bass you will likely need to raise idle rpm or add a supplemental battery.

One can run all cables on one side of vehicle. Either the electrical cable or the the others need to be shielded. Shielded cable is more expensive but time is money.

I think it’s 2 x 4ohm wired in parallel due to the onboard Amp feeding 2 Ohm speakers throughout the car.

[@MichaelHunter-wz6ru]

If your amp is 1 ohm stable. Google the specs of your amp

I wish I watched this before for I got my system installed. The person installed my system made my system a time bomd

I have a orion xtr 2500 with 4 orion xtr pro 12 wired at 1 ohm, 200 amp alternator ,ran 4/0 for power and ground also have a run of 1/0, the ground is bolted to the chassis, big 4, northstar agm up front and a group 31 agm in the back, yet I still get huge voltage drop the music starts sputtering and shuts off at times. Any idea? Maybe bigger alternator?

[@NextLevelCarAudio]

Do you still drop off voltage if you rev up the engine during the music playing? If voltage drop reduces or disappears then yes, you need more alt power. Goal is to have enough alternator power where you don’t drop more than a volt full tilt at idle.

I have the grey kx1200.1 . I want 2 subs for this amp What rms/ohm should I get each ?for it's full potential Since there will be 2. Thanks my man. I'm getting American bass subs. Subscribing

[@NextLevelCarAudio]

I believe that amp is 1200 watts x 1 rms. So you want subs that are close to 1000 watts combined. So 500 watts each. 500 watt rms Dual 4 ohm voice coil or 500 watt rms single 2 ohm voice coil will get you what you’re looking for. A 1000 watt total load at 1 ohm.

Hehe. Sony Explode subs in thumbnail

[@NextLevelCarAudio]

Lol, you right :P

[@BiG_Daddy_Hollingsworth_843]

This is a lot of information for beginners it's helpful but I wish there was a Visual along with it

[@Janatheus7497]

Ok so im doing research before I start my first build …you said power and audio on opposing sides, I was wanting to run my power by the driver door and my audio down the center is this far enough apart or should I route it through the passenger side, I do intend on putting 2-4 LiFePO4 batteries from the truck bed (in a toolbox w/a dc-dc charger and a few other goodies in there) and run that wire up through the driver side to the amps still same setup for audio wire

[@Janatheus7497]

Im still unsure on where I want the amps I do want a good air flow from the ac to them because I have seen overheat and pop

[@janrdoh]

The one annoying vibration I can't solve is the damn rear view mirror.

[@PistolPetesTattooSaloon]

Where you shop located bro

[@NextLevelCarAudio]

I no longer run a shop, just put our informative video is now on KZbin

[@kmccorkle69]

Grounding! If you have a unibody car(no frame) then You should be able to ground at the seat mount bolt, as long as you clean the surface free of paint.

[@RodofAllTrades]

This is one of the better videos that I have come across. Well done! I'll definitely share this!

[@NextLevelCarAudio]

Awesome. Thanks!

[@arturoperez5015]

My question is I am running a factory head unit with a lc2i converter to a rp-800.d skar amp to a 15 skar svr sub paralleled to 1ohm and I am experiencing voltage drop would a capacitor help in my situation

[@StickyFingerss]

No get a high output alternator or Lto battery

[@devinrivers5808]

I just stumbled on this video.. I have 2011 Nissan Altima, it has high mileage...I bought a Bose radio/cd player this spring off of eBay..the radio matches my car..I got my radio from UPS..and I got my money back, I found out from the dealership that I need an amplifier so the radio can work properly, I’ve been trying to find an amplifier and etc.. and I don’t won’t to spend too much money on my car, because it’s an older model Altima, want kind of stereo system/ speakers do you recommend that won’t break the bank

[@NextLevelCarAudio]

You can factory integrate into your existing head unit. No problem. I’d get a good set of components. (Woofer,tweeter,crossover) for your front doors, and an amp to power them. Then a subwoofer and amp for your trunk. Size/power depending on how hard you want to bump

[@burleykleve5752]

Can you hook your ground up directly to the battery?

[@NextLevelCarAudio]

Yes sir. I do in my current build

[@sampayton2225]

Thank you so much for helping me put things in perspective for me. I am new for doing a build, I’ve been wanting to do right the first time, and planning for every contingency. I don’t know if I have everything down. I would like if you could give me some insight to help me make sure I’m on the right path to make my first build special. Kinda a budget build.

[@NextLevelCarAudio]

Let me know what you need help with. No problem

[@brostugen]

15:11 I think you meant pulling your cca and replaced them with ofc

[@genericdude6551]

What person in their right mind would put a 10 kW amplifier in their CAR?? Even 5 kW is way too much. Or are they deaf? I might do 2 kW but 1 kW is probably more than enough. My home stereo isn't anywhere near 1 kW and I hear it just fine. Save your money by putting in a reasonable audio system.

[@NextLevelCarAudio]

Same reason people put 1000hp engines into cars. For show, race, competition. Car Audio is a huge arena for people that are into it like that. Just because you don’t participate or understand our world does not mean it does not exist.
