    36 ah's would be fine for 1kw rms. It'd try it.

    assuming the batts are in good shape then it certainly wouldn't hurt to use them. How many do you have? I run several C&D's which are just big *** UPS batts, 134aH each...

    Got em in and no dimming a drop of about .5 volts. But now I have a whine when car is on only from headunit. Can't figure it out but I do know it only happens when there are two sets of rcas hooked to preouts.
