underhood batt power/ground wire -----> batt in the back. Could also ground the back batt aswell. Easy stuff...batt terminals or crimp-ons...both will work

could you please elaborate for me ...so are you saying run wires from original battery pos/neg to new battery?

Run both power and ground wire from the under hood battery to the rear battery. Grounding the back battery is not needed but is good as well, although I dont know what the hell you have for power....

Would you kindly tell us what amp you're running, what size alt, underhood batt stock/upgraded?

Run power wire from front to back. GOOD ground in back. GOOD is key.

Not really the best way as in a moderatly loud system...

OP, tell us what your running...

You def wont need it. Just upgrade your underhood batt. Do the big 3 if not already done. You're done, easy stuff.

Villeza you're just plain wrong on recommending he run a ground wire all the way to the back. What would make you think 1/0 copper would have less resistance than a huge steel frame? I know in our blazers the frame has less resistance than a few 20 foot runs of copper. Geez... where did you even hear that?

Lol really, make a thread about it, let everyone flame you, then come back to me and tell me you're sorry...noob.

OMG, I'm about to give up on helping newbies....

Yes, doing the big 3 make a big difference...HENCE the" BIG" in "Big 3". There is also a big 5 but that's only for big system like mine and above.
