Battery Isolator

[jnc2000]

i need a battery isolator b/c my new setup is going to need a second battery. i am planing on getting two bx1000d's and two subs that can handle that power very easily.

now i am looking on parts express and i canot seem to find one. i located one on ebay but i am worried that 80amps will not be enough. any suggestions?

Napa...

Get one rated for your alternators amperage or greater. If you have an 80 Amp alt, an 80 amp iso will work, but I would suggest a 120 or so.

Anyways, go to Napa. Have them look in their recreational vehicles catalog if they tell you they cannot find it.
