Sounds like your system might be clipping - cutting off because it can not supply enough power to the speakers.

Wahat size are the subs, are they wire in series or parrallel?

Are they 4 or 8 ohm speakers? what is there power rating.

Could be that they are drawing to much current for the amp.

Could be your power cables to the amp are to light, and not supplying enough power to the amps.

I used to be vague..................Now I'm not so sure

they always say your better off to have too much amp power over too much speaker power.

How did you connect your amp to your head unit? Does the head unit have amp pre-outs or did you just connect the ams up to a couple of the speaker outputs?

If you connected it up to the speaker outputs on the head unit you are probably overdriving the amp.

have you got the amp setup to run as mono or stereo? you'll find it will put more power out to each speaker setup as mono than it will as Left/Right channels
