I am in the final phases of finishing my stereo install, and wondering if anyone has experience with putting a second battery in the back of a DC2 Integra hatch, and where it was grounded. I see one decent stock bolt, but it is real big. Any suggestions on a good ground for a 1/0 ring terminal?

 

theres a square piece of metal in the rear and center of my car that my battery is grounded to.

but you can drill a hole, scrape some paint, and ground it anywhere...

 

Is it necesary to have two batteries? Cause I have a 500w amp powering my speakers, and a 1000w powering my subs, all alpine type s stuff and I just run it off my stock battery and I haven't ran into any problems. I'm not trying to be sarcastic it was a real question I was wondering if I might have some problems down the line or something...

 

I have 2 mono amps (1200 watts RMS total), 2 channel at 150 watts RMS, 500 watt power inverter, 400 watt power inverter, carputer, 30 neon tubes, 2 underbody neons, whelen strobes, and yes it is all necessary, lol
I originally had an 11" comp sub along with the four 12's, but before the install I removed the 11" because I decided it would sound off with the other 12's (11" at 900 watts RMS, 12's at 300 watts RMS), so I removed it and put a 17" xbrite screen in it's place.

 

i grounded mine by lifting up the carpet and trunk board and just found some randomn bolt and grounded it there. just make sure you have a long cord so you can hide most of it behind carpet and it wont get in way.

 

Holy batman pimp my ride style.

You put 2fast2furious to shame with that thing! lol

But something like my setup I wouldn't need 2 batteries...?

 

yes, there is no rational purpose for 1/4 audio/video equipement in my car, I just got carried away. at least I am looking at upping my boost from 7 psi to hopefully over 20 psi after I have a lot of motorwork done this winter. my goal is 400-500 hp. who says you can't have 400 lbs of stereo equipment and be quick

 

I wanted to double check, but this is NOT an acceptable ground right? I would want something more solid? I just hate to have to drill a 1/0 hole through the car, and then drill another hole to bolt to.

 

When I relocated my battery to the trunk, I used the very large bolt that holds the seat belt in. Works perfect and it's only about 3ft of ground cable at the most.

is this the bolt you are talking about? do you think I should ground both the battery and ground d-block to that bolt, or should I ground the dist block to the bolt with the question mark? I have 3 amplifiers and a capacitor running to one block, and then I need to ground to one point, maybe the circle with the question mark.
