So I'll give you my run down on what I got and my issue. New 75 amp. Alt. Bluetop Ultima Battery 3 months old 4 gauge Power wire running back to the amps connected first to a Rockford Fosgate 10 Farad Digital cap. Power BD1000 Rockford Fosgate amp. running 2-10" DVC 2ohm T1 subs in a sealed box. Phoenix Gold 4 ch. Tantrum 400.4 Diamond Audio Comp. D6 6-1/2" front and rears. My Issue is I cant keep a constant amprage draw for my amplifier. It runs flawless for about 1-2 mins. and then its starved for power and the bass is much less with excessive headlight dimming. I have heard that the wiring in the older cars could be the issue, but not aware of how to start to fix it. So my only thoughts are I either need to fix the wiring or buy a bigger Alternator. I have never had a problem like this before owning a similar system in a Honda Civic which had a less ampreage Alt. and a much smaller Cap. Any thoughts or suggestions would be much appreciated! Thanks Corey P.S. as I have heard on the 12 volt site Im going to do the "big 3" I hope that will help, but Im skeptical since I have done many Installs and never had to resort to that. And Im looking into converting my 4 gauge into 1/0 Gauge.
Yea I had to replace the stock one due to it puking on me and didnt have the $300 to do the 220a upgrade.. But everyone seems to believe the Big 3 is the real deal! Thanks =) Corey
