Hi I have the 08 galant GTS and am running alpine type R 6x9s at the back and infinity kappa components in the front all running off of a 4x100 watt RMS amp. Now i am getting the pioneer tsw3002 sub which will run off of a 1000watt RMS amp and i think the alternator and battery wont be able to handle the load. I want to know which high current alternator and battery will fit. Any suggestions
