such a small battery would be atotal of 36 but still a small reserve

no you can. but even them in parallel doesn't provide much amperage. only 36.

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.
