How do you install a second battery in a E36?

i wanna know what you got in there that needs so much juice. i garuntee you there are more things you could do before installing a new battery. A battery wont provide you with any extra "juice" but it will allow you to play music for a long time with the car off. If your amp is struggling to pull enough power, i suggest a new higher rated alternator, and if you got 1000 watts or so a 2 farad cap.

the problem is when i am at a stand still the bass would hit then disappear. When i give the car some gas the bass will appear. I think everything came about after installing the UUC Altenator Pulley. Would a farad cap, or extra battery fix the problem.

I am running the following:
- 2 10" Orion XTR DVC Speakers
- Crossfire BMF 600D Amp

there is no way you require a second battery. I would upgrade the alternator first. I believe in 1995's, you have the 80A one, you can upgrade to the 140A one, forgot if it is called Valeo or Bosch.

You might want to also consider not underdriving the alternator.
