SaturnL200

So I currently have a 120 amp alternator and a optima red top battery for my Saturn L200. Along with a 7" boss audio head unit, 4 Polk audio mm6501speakers hooked to a pioneer GM-D8604 amp. Then 2 polk audio mm6501 and 2 boss audio MR650 speakers hooked to another pioneer GM-D8604 amp, along with 2 12" subs run by a 2000 watt rms vm audio amp. My question is what amp alternator and battery do I need to keep my car from continually dying? Yes I have done the big 3 and have a 5 farad cap already. Help me!!!

If you listen to music with high volume more than 15min , It is better to go with 2 optima red.

What about the Kinetic HC 1800 with a 240 amp alternator?

I prefer same brand and same size of battery...
