I'm upgrading my stereo equipment in the near future. My lights are already dimming with the minimal system I have. I've read that the dimming lights is basically telling you that your alternator can not handle the load, thus I'm buying a DP 160 alt hopefully. I would like to get a new, nice battery when I put the alternator and the new subwoofer amplifier I have in the car. Fine and Dandy.

Can someone please recommend a battery for use with a heavily loaded system, and to handle the Michigan winters? I don't understand the CA and CCA ratings. I've heard good things about Optima batteries, and I see them all over everyone'* signatures.

Alternator, sub amplifier and battery all at the same time is bascially what I'm doing.
Just need a good battery for the load and Michigan winters.

Also, has anyone ever upgraded the chassis ground from the chassis to the negative battery post? I've heard that is a good idea also.


Thnaks you guys.

I run the 160 with an Optima red top. If this is going to be your only (or primary starting) battery, stick with the red. I upgraded the charging wire from my alternator, as the first year running on the 160 crisped up the insulation on the lug.

Definitely change your battery at the same time as the alt. That will protect both. Autozone usually has some of the best prices on Optima'*, and if you save your receipt, warranty replacement is EASY. Just find an Autozone wherever you are.
