I'm Not Getting Much Output From My Subwoofers | Car Audio Q&A

This is a question we get a lot; "I just installed my car subwoofers but I'm not getting a lot of output. I see them moving but I'm not hearing too much."
If you have two subwoofers and you're experiencing this problem chances are your subwoofers are out of phase. This is a simple wiring issue causing the subs to cancel each other out. Basically your subwoofers are working against one another.

Alan, I agree with what you said, important when someone is new to learning something that you show them respect as we were all there once. But let’s not forget that if you are the person that is new you should show respect to those who taught you something new. For instance, let’s say you were completely new to fabrication, you learned a ton from someone else’s KZbin channel, and then started making your own videos showing the same exact thing…. but without giving a proper shout out. That wouldn’t be showing very much respect would it? I think it’s important in this small community for us to all show respect. Something for you to think about…

[@doublemanson]

🛑I had this same issue with my system, I solved it by adjusting a setting in the head unit, the 'subwoofer level' was at zero, which I thought was similar to bass boost so I didn't adjust it, but after contacting kicker because I thought it was my amp, I was told that it's not a bass boost and I should turn it up and re-adjust the amp gains and it worked flawlessly.

[@PHILLY214]

+Dane Brown ohh yeah it just reverses the polarity...play a rock/punchy bass song and switch it to 180 the woofer will suck in...but if its 1 woofer or multi. in sep. chambers it wont make a sound difference

[@realkbc1]

Believe it or not the sub phase can be out of sequence of the rest of you stereo system. Meaning the sound takes a bit longer to catch up to the rest of the sound coming out of the other speakers, so you flip the switch in order to work in sequence with the rest of the system. Almost as if you reverse polarity for the speakers. This is beneficial when using multiple amps and different speakers firing in different directions. You can play with the phase switch on each amp to achieve the best sound from the stereo system.

I try to help people in the comments sometimes that haven't had a reply to their questions. Car audio can be difficult to help people with just by communicating on KZbin.

@@_bauer thanks for the kind words. I looked up your amp and speakers. Very nice stuff but to be honest with you😬 I would have bought 2 Rockford fosgate p3d410 and a pioneer GM-D9701 and saved $860🤷‍♂️. The t1d210's you have are 2ohm DVC. Wired parallel you going to get .5 ohm load off amp. Your amp isn't rated for a .5 ohm load. You should have bought 2 Rockford fosgate t1d410's. Wired in parallel to get 1ohm from amp. 1600rms@1ohm is what I seen rated for your amp. You should be wired in series with your current subs. Bad part! You only going to get 700rms @ 4ohm from your amp. That's why its important to correctly match amp and subs. So you don't waste money on expensive amps and subs that you can't use to their full potential. I'll leave a separate comment about your radio 👍

[@Silentjustin06]

@@_bauer Ok, your stock radio is probably holding you back. Idk anything about a stock 2020 Honda accord radio but a aftermarket radio would better. I'd recommend a pioneer double din. One that has (NETWORK MODE) and Navigation and steering wheel control capabilities. (LOC) LINE OUTPUT CONVERTER I'm guessing. Again, dont know much about them. I've never used one because I always use aftermarket radio with amplifier and subs. As far as hardly any sound from your system. It could be a number of things. I would make sure that your wired correctly first. You may have mixed some speaker positive and negative terminals the wrong way by accident. I do it sometimes. I would go to a shop and ask them what they think. I'd recommend selling your amp or subs to get the the proper amplifier/subwoofer combination. Your probably better off selling the speakers. If your going to have 2 DVC subwoofers. It's best to go with 2 4ohm DVC subwoofers if your amp lowest impedance load is 1ohm. If your going to use 1 2ohm DVC subwoofer. Then get a 2ohm subwoofer DVC and wire in parallel to a 1 ohm load

If you have a trunk instead of a hatchback style car. A sealed box is probably best for a trunk. Ported is usually for open cabin spaces. Like the back of a SUV or hatchback car. Did you buy a proper size box for your subwoofers? If you dont have the proper air space for your subwoofers. That can affect the amount of sound you get out of them.

[@MushroomKingdoom]

I have very low volumen from my subwoofer. I connected from the factory stereo the sound to the aftermarket amp by the rear left speaker terminals (high input connection). I think I have to check the polarity of that connection and benchmark the results. also after that check the polarity of the outputted signal from the amp to the subwoofer to see if I solve the issue. ALSO maybe I can fix it connecting both the L and R inputs because I only connected the L. If success I will show my results here after that.

How about some love for the moderately not-so-newbie people. How do you design an efficient subwoofer enclosure with very little box rise. Sometimes just having a 2 cubic feet enclosure to a single 12 per manufacturer spec just does not cut it output wise and when you clamp test it, it rises to 4 ohms when wired to 1 ohm, sometimes higher depending on the frequency played. How are these other people building boxes with less than .5 ohms of rise, wired to 1 ohm and rising up to only 1.6 or so?

My question is how to get bass where I like it. I do not like the very low deep electronic bass. I want it to sound like being in front of a live band. Like a hard-hitting PA speaker. Many years ago I had 2 EV15b in a TL606 enclosure in a large SUV. Loved the bass sound, but do not have the room for even one 15 inch speaker and also know the sound can be tuned up using the right enclosure, but not sure of where to start. I am guessing I need something tuned to about 65 - 80 instead of 35hz. I may play with the subsonic filter to limit deep bass but not sure of that approach.

or maybe his box is tuned too high and he was expecting more lower range, that's why his woofers are moving like crazy

[@_JoeMomma]

Well my dumbass bought a prefab 4 years ago tuned to 47hz where as my woofers spec out at 32hz tuning in a vented box and they still got decently loud but the lows where lacking very much because it was tuned so high. I guess I could’ve added extra length to the ports but it also would’ve messed up the internal volume as well. I now have a custom box at 3.0 cubic feet tuned to 32hz and the lows are much more pronounced. So a higher tuned box will still output some decent spl at higher frequencies but will drop hard once you go down low in frequencies. So, moral of the story either buy/build a box to the specs of your subwoofer or get a prefab that is really close and the difference is night and day.

He didn’t mention this but laser aligning your speakers try it it’ll help you

[@djprojugs6606]

At first i thought he said the video is about "subwoofer hilarity"

[@classicsniper3457]

Explain why my amplifier is pick up the sound of my engine

[@mattparker510]

Bad ground

[@domanater480]

Gain to high

[@anthonysandoval965]

hello sonic.i have a question about stiffening caps, actually I got a few. 1 how does a cap discharge power. does it only discharge what's needed or the full load of what it's rated for. 2 I have a 500 wat alpine amp but I'm still getting the whole dimming n amperage drop and I have a 4 farad sound stream. I'm aware of the rule of thumb of 1 farad per 1k wats so i was also wondering if I hooked it to my amp would I potentially damage my amp. don't kno if it makes a difference but I have my subs wired at 2ohms. thank you for your time and insight it's very much appreciated.

[@malibumassey2393]

I have 2 American bass xr12d4 on an American bass ph4000md wen I turn the knob up it's then it goes out then comes right back on is it cause I dnt have the battery on it yet

[@kccokilla8374]

I have a sundown audio zv5 18" sub and I have 8 gauge wires for speaker wire. My amp is a sundown sae2000d so it definitely cannot shove the speaker anywhere close to max. It use to be extremely loud then while it was playing it seemed to loose the output it had. No power lose at all. Wiring is still the same at 1 ohm. Why does it seem like it has a higher resistance?

[@trillwill69]

Test the impedance with a digital multimeter. It could be partially "blown"

[@timothyhinton5665]

that box looks pretty sweet. is it prefab or custom?

[@sirlanceem]

+Timothy Hinton it's prefab i bought the same box but for 10" subs from them.

[@SonicElectronix]

+Timothy Hinton Yeah, its a prefab Belva ported box

[@timothyhinton5665]

+sirlanceem what is the air space and tuning on it for tens?

[@sirlanceem]

Timothy Hinton Number of Ports 2 Tuning Frequency 40 Hz Port Length 11.675" Box Volume (Each Chamber) 0.71 cubic feet

[@timothyhinton5665]

+Sonic Electronix I checked it out.. it seems tuned way too high for my taste...i need something tuned around 32-35 after displacement..and 16 square inches of port per sub for two tens..do you sell anything like that? They want $200-$300 for a custom box

[@originaldjgunfinger6568]

can you connect two different brand name car amp together and how to

[@stankinsteinfrankfurter9005]

I recently switched out my old audiopipe 1500 apcl for a skar rp 2000.1 to go on my single 15 inch evl and the new skar amp seems to not have the output the cheap audiopipe has I then rehooked up the old amp and everything is normal and loud! sent the amp back to skar to test it they said its fine when I got it back I hooked it back up and to no surprise the same result the audiopipe is louder! this shouldn't be I went around with a dmm and everything tests fine im stuck!

[@williamclay1781]

Thats crazy. I have the same problems with the same exact amps. Still can't figure it out

[@williamclay1781]

Took apcl 1500 out. And then akl i did was lay the rp2000 in the same exact location, wired it up, and i don't get nearly half the bass response as i do from the apcl1500. If you solved the problem please shoot me a message and let me know!!!!

[@AR_DRIFTER_JEB]

Really dumb question and I think I figured it out gunna try after work but this is how my subs wired rn. Amp ( - ) two wires running to each ( - ) on each sub. SVC btw and then I have the positive running as if we're parallel. My subs randomly worked for 5 or 6 hours then next day they don't work. They work but sounds like shit and slowly cuts in and out. Guess that's the issue cuz I checked everything else. Any thoughts?

[@masquinongy4652]

I need some serious help with my subs. I have no clue what settings or what settings I should set my amp at. I'm so lost. My aftermarket head unit has all these settings on them, and idk if I need them on or not, and idk what any of the dials and switches do on my amp. If you could help me, please get a hold of me.

[@grimreaper7862]

if your head unit is cheap and not giving proper voltage through rca it wont sound right ether

[@Aronsson007]

Pioneer DEH-X7800DAB does that count as a cheap headunit? i wouldn't but i have a similar problem, my subwoofer cone is barely moving even men maxing the gain on my amp, dont know what is wrong, any possibility you know what the problem is?

[@grimreaper7862]

is your subs hooked up right 2ohm 4ohm?your amp reads the ohm load like mine is 2ohm stable so im getting max watts from it but stock alternator and cheap battery so not getting full wattage

[@Aronsson007]

my sub is a B2 is12 2ohm DVC sub, first hooked it up in series thus getting 4ohm, i got a gas pro 1000.1 monoblock that can send 400w at 4ohms. even when the gain is maxed there is barely any movement in the cone... i rewired the sub to parallell, 1ohm, amp can push out 1000w max at 1ohm. here aswell, almost no cone movement even at max gain... checked all the polarities on the cables from the sub to the box terminalcup to the amp and all checks out fine... im really heartbroken about it because it seems like no one on the internet has the same problem as me and thus no solutions for me to find... you have any idea of what it could be? crossovers are not set, neither on the headunit nor the amp, tried setting it on the amp but without any improvements, amp is rated 1ohm 1000w stable btw

[@grimreaper7862]

Rca's might be bad or maybe headunit or possibly amp could be bad are you sure the amp is cutting on? Sounds like a problem with rca wires

[@Aronsson007]

Daniel Lloyd I'm not in the workshop at the moment, it's 01.00am here in Sweden haha but I will check everything I can afternoon. I use the same rca cables to the front and the rear so I'm doubting it's them but hey.. even individual cables could be faulty. I'm gonna check with a multimeter tomorrow on the amps terminals to see how they behave. I also have a neighbor who works a lot with car audio, asked him to come over and have a look at my problem. i got work in 6h lol I'm just so desperate for a solution, can't stop searching around haha

[@DEMONJOKER69]

I’m having this issue, I got mine wired to 1 ohm and my amp supports 1 ohm. Could it be my electrical isn’t good enough to supply the proper power to my amp?

[@radianm6]

4ohm better

[@SleepyBoiii]

Will the length of my jumpers affect subwoofer output ? I left the jumpers really long i have 2 dvc 4ohm parallel to 1ohm

[@rmblwgn]

What gauge wire and is it real copper or copper coated aluminum

[@manny903]

Hey I have a question okay I got a nvx jad 1200 at dyno test it does 1300 rms certified I had a nvx vcw 15 1000 rms dual 2 ohm hooked up and hitting good but I took the sub out put it in a different car with a cheap power acoustik rz1 2500 only rated to be 2 ohm stable at dyno test of 630 rms at 2 ohm but it runs at 1 ohm no problem so that nvx 15 dint last 40 mins with that amp and it blew so I’m guessing either that amp does way more then 1300 percent me at 1 ohm or I have an electrical problem with my nvx amp that causes it to not run the potential wattage but I have a a second battery and the power wire I know is good power stay at 14.0 volts so could a bad ground cause the amp not to reach its potential

[@99hari55]

I have a subwoofer two 10 inch 100 watts each and amp is tda2030 dual ic bridged for each channel transformer is 12 0 12 5 amps....normally its works fine and Good bass but higher volume level distortion starting like low powerd ...why...?

[@mmishramanu0]

Hari K Nair bro. Pls use 24v 10amp most. Your problem will slove.

[@jmercado418]

I have a 12 in Kicker sub sand a 1000 watt mono Boss amp. Had it installed and worked perfectly for about a year. Sounded awesome even with the stock speakers in my car. Now, I'm still getting bass but it doesn't pump as loud AND now the stock 6x9 are rattling. This NEVER happened beforehand. I NEVER touched the settings, I checked for any loose cables, and EVERYTHING is the way it was when it was installed. Any ideas as to what happened and what I need to check? I did notice 2 fuses. I didn't check those. Will those affect the sound?

[@tomtricks6838]

nah fuses are just for power and only need replacing if blown

[@vincionyou]

So my amp worked playing this video but not when I play actual Music

[@sckopegarcia8040]

U helped thanks bro !

[@pontiachotshot]

My problem was my bass boost and Gain on the amp and not having my sub output turned up high enough on my deck

[@Graceology101]

or where can i get the Samsung wiring for it

[@jcinewilliams8819]

There is no wiring link just text explaining what you said on the video

[@IssCameron]

This is happening to me but I only have 1 sub, idk what's wrong

[@xgreenbaynationx9812]

Yea mines is soft with 1 12” sub Rockford fostgate P3 why is that???

[@leonknight2599]

Lol my phone don't have the frequency response for me to hear the sub on first demo
