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.

Shout out to the NEWBS! We were all there at the beginning. And videos like these taught me so much. So glad you guys make videos. Wired up four TXX-BDC2-12s dual 4 at 2 ohms. On an APCLE30001.D.

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 YouTube 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…

🛑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.

You should also check if the ground is connected securely to the chasis. You lose power and clarity if the ground is lose.

i had mine hooked up this one time and i notice the same thing and i just switched the main output wires around and they really made a difference. btw they are 2 12 inch l5 dual 4s

Thanks to you my neighbors hate me again you’re the goat 🐐

I bought a nice used custom box with a massive audio hippo sub. Took it home it sounded like crap. Removed sub and it was wired crazy. Wired it up correctly and it was violent smooth bass!

I would've killed for a video like this in the mid 90's when I was in highschool trying to hook up beat in my buckets.

I've got my gains, and bass boost dials turned all the way up on a 1500W BOSS amp, hooked up to a single 400W Kicker Sub, and it works, but hardly kicks like it should. I wired it through my factory speaker wiring, but I feel like my factory wiring is somehow limiting the output of my amp.

Please explain and possibly demonstrate the use of the PHASE SELECTOR switch or knob on a crossover.

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 YouTube. It's hard to diagnose someone's problem when they cant relay the information properly and dont understand what your saying. I try tho because I've been there myself so..

My kenwood single din player, on the rca output for the subwoofer there is no sound coming out, but wen i tried the rear n front output i get sound....checked all my wires n fuses and everything okay

[joshsilva]

Is their another link for the wiring diagram? I’m trying to put two dual voice coil 10s but the link doesn’t work for me

[calebr]

I had one 10" and an amp and it hit really hard so I decided to upgrade the amp and sub and get two 10" subs and they barely hit ik my wiring is good what could be the issue

[BeeDogg]

But you know another thing is that he might have his woofers in a sealed box and most people don't know certain speakers do not perform well and seal boxes I always recommend ported because when you build a sealed enclosure it has to be the right size specs for that speaker and most people just buy a box and just throw some speakers in there just to have sounds and then come to you the technician and ask you why is it not right first of all you got this big ass amplifier on two 10 inch subs in a sealed box and is going to sound okay but you get used to it a lot faster and that's a lot of people problem I recommend Port it because you don't need as much power they can take the power but the sound is just more dynamic when you can move air some people just don't know what they have a lot of times and a lot of people be having good equipment but sometimes I have to be honest it'd be alot of the shops just trying to make the quick dollar instead of explaining and giving a customer what they want instead of just throwing something in their car most people will pay for what they want but you give somebody some and put it in the car and then you get responses like you are receiving today and I'm not saying all shop but it's a whole lot of them this just about the dollar instead of the love other music and the installation game I never said don't make your money but if you know this speaker and this amplifier is some why sell it to the customer unless they say I want something cheap

Thanks this video helped me a lot. My subs p3 Rockford fosgate where not wired right then I wired them how they are suppose to and now I get strong bass.

[fadedxmist]

Mine is doing the "out of phase" so I wired everything up but used some wires that didnt come with the kit, which is very skinny like factory stock skinny, and I wired both my 6x9's with that wire to my 400watt boss amp. Could it be that I didnt used Speaker Wire? Or is something actually wired wrong

[kyleh]

I have a 740 watt pioneer amp and a kickercvr 12 and ik I wired it right at times it hits hard perfect other times you can tell when the bass drops it just gets quieter but not like distorted or nothing just quiter and theres a dramatic difference my amps not going into protect or seem to be getting hot it's wired at 2 ohms ATM I tried wiring at 1 ohm and 4 ohms and all does the same thing no matter how I wire it so I bought a 2.5 farad capacitor thinking that was maybe the problem tho it's stopped my head lights from dimming the bass still does the same thing and had no effect on the amp it remains anywhere between 13.8 volts to 14.2 so ik its not the voltage going threw I have 8 gauge wire going from the amp to speaker and the rest power ground wire are all 4 gauge I don't believe it needs anything bigger for a 740 watt amp tho it is older still I don't see it putting out any more than 1200 watts (and yes my ground wire is grounded good sanded it down to bare metal and have 14 bolt that the ground wire screws on) any suggestions on why this is happening?

[ishaannan]

Can you make a video of how to check rca cables
