Is 8 AWG enough for 2 amps?

[Ethosb 10+ year member]

Currently have an Alpine MRX-F-30 4 channel amp installed with 8 AGW. Am adding a 10" sub that will be powered by an Alpine MRX-F-50. Instead of runing a completely new 8 AGW wire I had thought about installing a power distibution block and then run the 8 AWG out to both amps. That would eliminate running another 8 AWG through the fire wall and will eliminate removing as much interior trim.

Thoughts?

I wouldn't run both off a single run of 8ga. You should swap it out for 4 ga put in another run of 8.

it all depends on how many watts you will be running...

Yea thoughs dont sounds like big amps, but i would run 4g from batt to your bistroblock then 8g to ure amps

The F-30 is 50Wx4 and the F-50 will be 300Wx1, both at 4ohms.

One run of 8 gauge should be enough for 500 watts total realistically. If your fuse blows from over current than swap it out for a four awg run.

yep, just fuse the 8awg for 60A and see what happens. it's likely you'll be fine.
