do i need to run a ground from the rear battery to both amps or just one like in the picture?ok thank you, i was planning on getting at least 25 feet. will you look at these to sketchs and tell me if one is better/safer than the other please? i would prefer to use the top sketch because it would be less wire(pic doesnt depict this lol).
this way?
or this way?
Run dedicated pos and negative wire from front to back battery. Then rin dedicated pos and negative wire from battery to amp. Plain and simple. Eliminate chasis grounds completely. You have a friggen 2nd battery, none of that chassis sh*t matters.
ok thx jeff. ive been looking at possible areas to run my power and ground cables inside and theres no way its fitting under my door trim. was thinking about running it under the car and it would be about 25 feet or so. would you recommend stepping up to 2/0 then running 1/0 from a distribution block near the amps?
if you havent bought the wire yet, then yes go 2/0 welding.
ok and how many fuses would i need? do the dedicated runs from front to back batt need a fuse near both battery's so 4 fuses total?
you only need to run one fuse on the positive run between front and rear batt. You literally are waaay overthinking this.
ok so besides differing on amount of fuses needed, do i wire the second amp as number 1 or number 2 in the picture below?
ordered from amazon and it arrived today, here is the link https://www.amazon.com/Soundstream-TN4-900D-Tarantula-4-Channel-Amplifier/dp/B009NLNY14/ref=sr_1_1?ie=UTF8&qid=1523080897&sr=8-1&keywords=soundstream+tn4.900d&dpID=41RVSF8uDxL&preST=_SX300_QL70_&dpSrc=srch
no problem, wasn't ur fault. so i ordered the nvx jad800.4......since its not owned by epsilon like sound stream was, it should still be the good amp correct?
yup, that brand at least cares about their reputation.
