Anyone here running a seperate battery

Just looked back at your older posts. Memphis amps are NOTORIOUS for being power hungry. As stated earlier a second battery is really a temporary solution for a bigger problem. A high output alternator is definitely the right approach.

Something else to consider would be the possibility of selling the amps your using and replacing them with something a little more efficient. The JL HD series Arc XXD or Alpines PDX comes to mind.

Gonna keep what I have currently for 1 more year save and then get a completely new system. Prolly mostly Image Dynamic stuff. For now can you recommend a good alternator? So I wouldn't need a cap then if I get the alternator?

I guess if I buy the alternator now at least I will have it for the next system.

This is really your best choice, Its a permanent and correct fix. Id look into DC power or Mechman alternators only because in your application you will probably need to have one custom built. If you end up running Image Dynamics amps you will be in the same boat. They are all current Hungry class AB amps, even their sub amps. I honestly think the cheapest way in the long run would be replacing your amps with a single more efficient 5 channel. I bet after selling your amps you would probably have almost enough to buy one outright.
