Since I'm getting an HO alternator, I'll now need a new fuse (the one that's by the battery). Alternator is 180amps. My sub amplifier's max draw is 160amps and the other amplifier's max draw is 75amps. What type and size of a use do I need to get. BTW I'm running 4ga power wire to distribution block, and short 8ga wires from there. Thanks!

That helps a bit, but I still have a question. My maximum current flow is 235amps, whereas the alt can only put out 180amps. Which number do I use here? Also, given the difference, should I upgrade the wiring?

Distro blocks are a pain because you have to use more fuses. I would just run two wires.



I would run 2 awg with a 200 amp fuse to the sub amp, and 6 awg with an 80 amp fuse to the other amp.

Cool, I get ya. I think I will run 2 wires. However, if I do decide on a distribution block, still use 2awg wire and 200amp fuse?

Oh yeah, I wanted to learn how to run power wire and RCAs through the car and was wondering if there's anyone in Los Angeles area who knows how to do this well (and I mean really well) that wants to do this with me. I'll pay and what not, let me know who's interested.

If you do end up using a distro block you would need to run 0 awg with a 325 amp fuse to the block.


As for the install, it helps if you have a service manual for your car that tells you how to take apart the interior. I'd help ya if I wasn't on the other side of the country.
