Coolwazabi Posted January 15, 2011 Report Share Posted January 15, 2011 basically its showing.. my front battery to my rear battery and then the rear battery to the amp.. and the chassis in the back to the ground of the rear battery to the ground of the amp... is this setup okay/safe ?? and also the rear battery is about 1/2 the size.. is that gonna be an issue ? thanks !

ACKAWILY Posted January 15, 2011 Report Share Posted January 15, 2011 It works when you do it that way and its also safe. Some people suggest groundin the amp to the chassis but the battery negative will work. 1995 Sonoma with camper shellJVC KD-R900(12) Incriminator Audio Lethal Injection 15s Crescendo BC5500 ( sent to me not 18v capable)(7) XS Power d1600(2) 350amp Mike Singer AltsStripper Pole FTW Member Build Under ConstructionYoutube Videos Link to comment Share on other sites More sharing options...

Alex K Posted January 15, 2011 Report Share Posted January 15, 2011 i say spend the 30$ and get a ground run too. I see ground noise if youre grounding the battery and amp in different spots. You'll thank me later when you have a + and - run to the back Helps a TON. Also, different sized batteries are ok. Unless you have like a duralast up front, kinetik 1200, yellow top, xs power all in back, then you're fine. I ran 2 different style batteries and never had a problem. 2006 Nissan Z Track.

ACKAWILY Posted January 15, 2011 Report Share Posted January 15, 2011 Also some people have different results when doing the same things. My voltage stayed the same even after I ran a negative from rear battery to front battery and I havn't had any static noise myself when grounding in different spots. But like I said, sometimes people get different results. 1995 Sonoma with camper shellJVC KD-R900(12) Incriminator Audio Lethal Injection 15s Crescendo BC5500 ( sent to me not 18v capable)(7) XS Power d1600(2) 350amp Mike Singer AltsStripper Pole FTW Member Build Under ConstructionYoutube Videos Link to comment Share on other sites More sharing options...

I had a problem when I ran mine that way, since the rear battery is grounded to the chassis, you want to ground the amp there too. That's why im saying just run another ground connecting the front and back battery. You wont need to fuse it, so itll be easier and cheaper then the power.Plus, youll never have to worry about sanding more spots in the car or finding grounding points if you decide to do more amps. it ends up being more efficient and easier to do installs when you basically have everything right there, if that makes sence. 2006 Nissan Z Track.

Alex K Posted January 15, 2011 Report Share Posted January 15, 2011 I had nasty ground noise with mine like that, and as soon as i ran a ground to the back, it stopped. It'll work fine the way he has it, but im just sayin a ground run will make life easier. 2006 Nissan Z Track.
