yea. but when i throw in an amp for my componets in another month or so, and i have to have the power to run my car normally, plus, with just my HU and speakers no amps right now, my car usually only runs at about 13.4-13.8 volts and drops to like 13 at stoplights, so maybe i should just spend the small cash and upgrade the battery and big 3?
thats really strange for your car to be that low now w/out a big amp. w/ my 2 amps i'm at roughly 1100 watts rms and my voltage does not drop below 13 i just have a red top battery and 1.2 cap.
