I have one Optima Yellow top battery in my truck and want to add a second in the rear for the audio system.  What battery isolator should I buy?  Its a deep cycle D34/78

I have a second battery in my truck and I used a standard battery isolater from NAPA. I beleive i only paid $30 for and it works great. A couple of model #'s for you:

782-1769 (Up to 95 amp altenator)
782-1768 (Up to 120 amp altenator)

These might not be around anymore, i bought it a couple years ago, but you can try.
