Hey i just installed my subs in my new car with the stock headunit in it (used a line output converter for the RCA's), but im not getting the bass that i did in my old car they were installed in. if i change the balance to one side then it sounds the same, but if its in the middle there is barely any bass. Anybody know how i could fix this?

double check your gain and frequency settings on the amp maybe? that or maybe its just the diff in headunits..my guesses.

The speakers are supposed to be phased correctly.
For me it means putting a 1.5v battery on the speakers. The cones will move in or out when this DC voltage is applied and if both cones move in the same direction, you're properly phased.
That's why the speakers and the wires have polarity designations even though audio is AC.

I suppose this could solve your problem and it's easy to try. Just switch the wires on one speaker.

Do this. If your speakers' phasing isn't correct, the sound waves cancel each other out.

Are you running the amp/subs "stereo"

If so (and very likely) you have one of your subs out of POLARITY. . Not phase..

Swap +/- on ONE sub (or for one sub at the amp) and the problem should be solved. .

Polarity is causing phasing issues.. this is why when your balance is on center you have no bass, your subs are 180* out of phase and canceling each other out..

As you move off "center" you also break down the 180* out of phase situation and the bass comes back

@ImFrumpy: Also, if you used your HU's rear speaker channels for the inputs to the sub amp and your car is a recent model , you'll need to use the "hidden menu" trick to disable the nasty factory EQ. Search for the threads here that talk about that hack.
