Two-battery Set-Up

[cqlink]

I have a '99 Tahoe LT, 5.7L. It has a place for a second battery. I'd like to use it to drive a new audio system and use as a back-up for the other battery.

Is there a sticky or link on how to wire it up?

Thanks in advance!!!

you can use the info above to do it...but its easy just get a selonoid and wire like this...

1 power from front battery thru solonoid to other battery then back to your amps
MAKE SURE YOU USE FUSES
2 make sure you ground the second battery to a good ground also......

3 wouldnt hurt to do the BIG 3 under the hood either.....

Good luck
