need some input on this system "revamp"

[toolskizm 0]

I just ordered a Fosgate T20001BD, 2 Fi Q 12's w/ Bp Power option, I have a JL 450/4 which will power a set of 6.5" Focal Utopias and a set of 6.5" Focal Polyglass.

As of now I have the stock alternator (2006 RSX) which is small..not sure exactly what it is. I have a regular batt in the front which has 2 4gauge wires runnin to the back. There's a 100amp fuse on each 4 gauge. These two 4 gauges run to a Optima Yellow Top in the back the car. This is where the two amps will be. Does the wiring seem sufficient for what will be in the car? And the fuses?...I may need to get a high output alt. for the car kuz of dimming...

Try installing it all first and see how things go.

If you get some dimming, first start off by upgrading the Big 3. After that upgrade your runs of 4awg to 1/0awg. Then move on to an alternator.
