Battery Isolator Question

[SKID18]

Ok, I'm currently running 600rms wattage plus other car accessories on my main battery. Think I need a secondary battery in the back? If so, which would work best and will I need a battery isolator to work with it?

I recently had similar question, and the answer is no, 600watts rms would not require a second battery, (though your signature says 800 rms), unless the "other accessories" you mention are really extensive electrical wise. A good quality battery up front won't hurt. I run 2 amps 995 watts rms total power and plan to get a Kinetik battery up front and no second battery.

More than likely a good solid main battery will be plenty. If you do decide that a secondary battery is needed take a look at this link.

There's a couple simple options for adding a 2nd battery. I do recommend a sealed battery no matter the brand. I'll also be happy to send you a diagram and some instructions if you need any help.

You dont need an isolator unless you want to play music with car off for a long time and just drain your back batts and not drain your front one to start the car

Well the thing is, my car would temporarily not start (for about 3 minutes), I went to Sears to get another battery because the first one was kinda old. I still have that lingering problem with my car not temp. starting so that's why I came with the assumption of adding a second battery.

You might want to swing by a parts store to have the alternator checked before you do anything else.
