[QUOTE="altoncustomtech, post: 5488602, member: 564410"] Hey guys, I've just got my van back from the mechanic (head gaskets). While there the system was out but I left the stupid CAP in and it got stolen. I've had it back for a couple of weeks now and I've had a few problems with it. 1) The Exide Orbital battery died, no one knows why but I replaced it with the second one I got for my car (upcoming build log) and it was DOA and never used so I've installed a Red Top. So the starting battery problem has been fixed. 2) Severe noise similar to white noise, turned out the little fuse in the Pioneer HU was blown, neatly soldered a wire into place and that problem is fixed. Now it was at the mechanics about 4 months (since late August '08) and I've been diagnosing these other problems for a few weeks so we've been easy on the system, no bumpin' too hard until here lately. I'll be dammed if now I've got a voltage drop issue and the lights are dimming. To fill in the background here this thing has a 250A alternator, BIG 3 is done, terminals and connections are clean as can be after changing the battery out twice. It only has one BXi2006D subwoofer amp running two BX12D2 Brutus subs wired series-parallel for a 2 ohm load at the amp. The voltage is dropping from 14.8 at idle to 11.5 on a bass heavy hit such as the ones found in Lil Wayne's A Milli. So anyone have any ideas on where I'm going wrong here. I should have a little more stability than that seeing as I'm only running 1900 Watts RMS total (when you add the Zeus 6006 running 2 ohms stereo) and thats more than likely an optimistic number. Any suggestions here would be greatly appreciated guys. --Also the alternator has been tested giving 260 amps of output at 2800 RPM and 112 amps at idle. [/QUOTE]
