hi.
i just purchase two of 08zx1500.1 mono and two of L7 2000 watts.
i install one amp for each speaker. one speaker works just fine, and the other is not giving the best quality sound.
i don't know whats wrong with it.
maybe the amps is bad? cuz i switch sides
and looks like the amp its causing the noice.
i should i do? to test the amp. or fixe the problem

L72 (dual 2 ohm coils) or L74 (dual 4 ohm coils)?

If you have an L72 and you're running the coils in parallel you have a 1 ohm impedance which the amp may not like.
It also sounds like you may have the subs wired at different impedances.

Or - your gain is too high causing clipping which sounds like a-$-$.

Or - with 1500w into 1000w subs (these are 15's, right?) you may be reaching the limits of cone movement - which, again, sounds like a-$-$.

Or one amp's filters aren't right.

Or with a pair of 1500w amps your electrical system is falling on its face, your voltage is sagging significantly and your amps are subsequently falling on their face.
