u have a tiny little 80amp alt

80amp alternator and 65Ah battery.

edit: that makes me sad:crap: where is a good place to buy an alternator from and what size would be appropriate?

the chain is as weak as its weakest point. This means wire size was not your weak point.

Here's the reality:

For constant, reliable voltage with a decent sized sub amp, you are going to need a good quality battery(s), a alternator up to the task, AND the big 3. You pretty much need all three working together to prevent voltage drop.

The Big # upgrade makes a more noticable difference with the larger alternators, your little alt isn't big enough to need larger wire, which is why you didn't see a big difference.

The best bang for the buck fix would be to add a second AGM battery in the back next to the amp, but the ultimate solution will be alternator + battery. You have to pay to play, unfortunately.

ok so what if my main battery is right next to the Amp, my main batt in the HHR is int eh back, amp is in the back also. I was thinkin about just doing a kinetik 1400HC.

I have 90 amp alternator and i was thinkin upgrading to 0 gauge through out the car.

Amp - PA 5500d gothic series amp. 150 amp fuse

plus 4 channel amp ect.

Should i not bother with 0 gauge? or should i still get 2 batts, right now from what i know there isnt an ho alty for the HHR yet
