Well let me know whatcha got that you'd be willing to let go for the price I'm looking for.
To give you an Idea, I have a 2000 Chevy Malibu LS, I've upgraded the Big 3, have a (HOA), upgraded the battery to a stronger battery, (But it's just an Auto Craft Advanced American Auto brand), a 2 farad Planet Audio cap, an Xstatic Super 100 (35 farad).
It will be powering (2) Kicker 4 channel ZX450 amps for component speakers, a Mmats 3500.1D running 4 Rockford P3 D2 12s at 1ohm.
Right now I have a Visonik V2908 amp running the subs at 4 ohms bridged doing 1200RMS. The lights don't flicker and I stay between 13.6 & 14.4volts when I'm driving. But when I'm at a light, I dip down into the 12s and finally 11 some odd volts and that's when my amp starts cutting in and out. Unless I cut the volume down.
I hope that helps.
