anyone ever hook up a 2nd battery? just wanted to see any good or bad info anyone has on this. thanks

 

well I have a 2nd battery as a backup battery for my alarm...hmm. I don't think that helped. but I tried

 

I've been thinking about that addition; but my total won't max out over 1,000 watts any more. So, probably not; just a 1.2-1.5 farad cap will suit me just fine. Batterys are definitely a good item to have; use Optima or Stinger batterys @ $120-150.

 

i have an optima now. i was toying with the idea of adding a carpc and was curious about having a 2nd battery in the trunk..,....

 

I simply have a more powerful battery for my audio.

 

its a more powerful alternator that you need. capacitors are only used to try and keep the voltage to the amplifier higher the 11.4v to prevent amplifier clipping.

as for a second battery, you'll need a battery isolator to control which battery to use and which to charge back up from the alternator.

 

Yeah, but so far, im having no problems cuz i dont fully use the available power.

 

how powerful is our alternators and anyone know where to ge an upgraded one from?

 

Has anyone tried to see if a Mitsu Endeavor alternator works in our car yet? Thought that it has a higher output...

Those are 2 good high output alternator builders. Its going to run about $350-$400 for our cars.
