I Currently have in my car audio system
I currently have

1 - Pioneer DEH-3050UB Head Unit (2 RCA OUT (Subs(Red and white) and Front(red and white)) )
2 - 12" 1200 Watt USAUDIO (Pre Cased) Single Coil Sub's
2 - 6x9" 240 Watt Pioneer 3 way Speakers (2 Ohms Each)
2 - 6.5" Round 220 Watt 3 way Speakers
1 - 600 Watt (2008 Model) 4 Channel Pioneer Amp (GM-6300F
(Runs at 75 Watts RMS x 4 @ 2 Ohms) (60 Watts x4 @ 4 ohms)

I Currently have everything wired to the one 4 ch amp as shown above, but am looking to run the 2 subs from this a 2008 PIONEER GM-D8400M 1200 WATT MONO BLOCK. The questions i'm wanting to ask are will i need a farad capacitor run in before the sub amp or will i be able to power both these amps at all?


I am running a heavy duty battery and an 80Amp alternator. I have only the standard aircon and lights to power apart from the sound system.
Any advice is welcome.

Basically, Can i power these 2 amps without complete headlight dimming, and 2, if i can, will a farad capacitor need to be installed to ensure constant current to the amp.
