- Wiring Bi-Amp System w/ Single Run Of 4AWG +/-

[Sutliff]

I am planning to use the 4awg of POS & NEG I have already run in my car to power my upgrade in amps ... Rockford T400-2 & a T500-1bdCP.

POS & NEG into good dist blocks then some 4awg POS & NEG Knu out to each amp.

I am also installing a brand new MechMan 170A alternator, & sticking with an OEM-type BATT that is in great shape.

Also will take care of the Big 3, though it will only be in 2awg.

I am not going to be in competitions with this car, etc., ... it is just for bumping around town & road trips .... not going to be pulling low, low end for looong periods of time.

I suppose the first downfall of my intentions are the single 4awg to run two rather high-end, high-drawing amp, yes?

What I am changing from, & changing to should be pretty clear in my Sig.

Thanks for any comments ...

since u going to do big 3 why dont u make a single run of 0 gauge and split it to two 4 gauge ?

For right now, it is semi-money issue, & semi because I am partially disabled & it was a bitch to run the 4.

I suppose what I am asking is what should I expect until I can go back through & do the wiring better ... until I can afford $125+ in cable & battery post terminals, etc.

I just took out my extra battery and have been running my 2 amps just fine on a single run of 4 ga OFC. Though both of my amps are class D and rated rather high on efficiency. You should be fine even if it is less than ideal. Just make sure you are using OFC and you are properly fused.

Turn your negative run into a positive run and use your frame as a ground is what I'd do

Good with the OFC, & will be fused within 18" of BATT, & within 12" of each amp after dist blocks. 3 fuses in all - actually I go circuit breakers.
