Hello, recently added a second battery to the system for whatever reason, I've never had any good ground spots in my 96 truck club cab other then the seat bolts which worked for my speaker and sub amp for a while but now however, the second AGM battery hooked up to the same bolt is like naaaaahhhh... my bass amp cuts volume then comes back after 6 seconds etc.... so now I'm in a predicament as to do i run another gauge run from the front battery negative to the rear AGM? I've read mixed reviews online i guess... i am from Old times where sure everyone thought you needed less then 18" for a battery ground, however, nowadays I see 80,000 watt rides with 12 runs of 4/0 negative from front battery to rear banks...
Just wondering if this will solve my problem or has solved above else's problem of similar to what I'm going through before I go get another run.
Again, will running another run of wire from my front battery, that is grounded to the chassis, all the way to my rear AGM be a sufficient enough ground for the AGM?... Also, i have 2 amps grounded of the AGM now as well. Thanks.
