Would this be ok to do?


Recommended Posts

Ok so what i am planning on doing is hooking up one amp to the front battery and one amp to the rear battery.

the way i would do this is hook up my 4 channel amp to the front battery by running the 4 gauge power wire straight to the amp from the front battery with one 100A fuse up there. Then ground the amp to the rear chassis.

then hook up my mono block amp to the rear battery by running the 0 gauge power wire to the rear battery positive with a 300A fuse by near the front battery and then another 300A fuse by the rear battery.

Then hook the monoblock amplifier positive to the positive terminal of the rear battery with a 200A fuse near the amp. Then ground the mono block amplifier to the rear negative battery terminal, and then ground the battery to the chassis.

then in the future if i wanted to add another battery i could just connect the new battery to the rear battery in parallel with no fuses because they will be next to each other and i would not have to ground the new battery because it will be grounded to the chassis from the first battery i installed (or would i have to ground both of the rear batteries to the chassis with each having a 0 gauge wire coming from the negative terminals?.

would this be safe to do? my monoblock does around 2000 watts and my 4 channel does around 100 watts into 4 channels.

if i should change anything or add anything let me know.

it sounds like you're going to run the monoblock amp str8 off of the back battery with nothing to charge it. The amp would just draw from the battery until it was worthless. I'd wire both batteries in parallel and then run power from the back battery to both amps. If the batteries are both AGM you won't need an isolator, if they aren't you'll be fine but should really get 1 to prolong the life of the batteries or just get matching batteries. Regardless of what you do you are going to need to find a way to charge that back battery

No, he did say that he has power wire from the front batt to back batt. You could do that if you wanted OP, but it'd probably be easier and save you some wire to run both amps power off the back battery. Either way you're getting 12V to your amps. Just make sure you have a good chassis ground for the rear batt

Connect everything to one point.

K.I.S.S.

The more complex you make something the greater your odds of something going wrong. The 1/0 from front to back will be enough to power everything without melting the wire you have now, so if in the future you upgrade to more power then you'll want another run from front to back and possibly more batteries to keep the power sustained without too much voltage drop.

Fuse the wire from front to back and you'll be fine.

Yes stock alt not sure what size and I am planning on putting 2 xps950's in the back , but I bought one for now to see how my voltage holds up. Thanks guys I wanted to do it this way because for some reason I think it is easier because I wouldn't have to mess with my 4 channel amp and i can leave how it is set up. I would only have to mess with my mono amp

wait a minute if i add a second rear battery (2 xp950's about 70ah total) would i need more than one run of 0 gauge from the front battery for them or will they charge fine or no different if i just use one run of 0 gauge and one ground from the first xp950? would my wire melt if i connect both of the batteries on the one 0 gauge?
