Power Options

My lights in and outside the car have been dimming badly for a while now, but I just replaced the battery, nothing special just a Deka that fit my car ('06 Cobalt LT, rear battery). Got it at a local battery shop and the guy said it would be sufficient but its still not, and to top it off i'm about to add another 500 watts to my system (leaving me at about 1500w total). The problem with upgrading the battery is that the amount of space to fit a bigger one before any heavy modification is lacking. Wondering what my best, and easiest/cheapest solution would be.

Thanks

I thought about big 3 but it seems like it would be a huge pain in the *** with a rear battery. Could I just add maybe another smaller battery?

ok replace engine ground to chassis with 1/0, replace battery ground to chassis with 1/0, now run a full length run of 1/0 from alt to batt, seriously how are you bitchin when you already save distance form batt to amp... you win some and you lose some.
