when i turn the volume up, it sounds like my amp is not getting enough power to my subs (they sound good through volume 1-25, but loose power at 25-30. i was just wondering what could be causing this. i already have a capacitor BTW
heres the main stuff
kenwood KAC-9152D with 4 gauge batt cable-900 watt RMS
Pioneer 600 watt RMS amp with 8 guage batt cable
2 alpine type r 12's
4 farad power acoustic capacitor
is it my battery/alternator?
do i need bigger battery cable?
if my battery goes completely dead do i need to recharge my capacitor.
P.S. my lights still dim with the 4 farad

Get rid of the capacitor, upgrade the big 3 and install a high-output alternator. Problem solved. ------------- Support the12volt.com

Read the sticky on capacitors. They will not solve a dimming light issue. Like what dyohn said, do the big 3 and if that does not solve your problem you need a higher output alternator.

If you are using the loudness, try turning it off. The loudness contour works untill a certain point on the volume control. It may turn off at 25 on your particular deck.

Correct me if I am wrong. If his volume only goes to 30, then @25 he is past 3/4 of the way on the volume. Which would mean he is sending a clipped signal to his amp. Maybe I read his post wrong, but that is what I got from it.

Yes, it is possible the signal is clipping and that is what he's hearing. Not all HUs clip at 3/4 volume, but it could be related to this issue. I still suspect power problems, though. ------------- Support the12volt.com
