I'm about to buy a 2400 watt amp for my '86 4runner and I want to get a higher output alternator to power it. I've heard of people swapping in GM alternators, but would that be just a bolt-on or would that require a lot of modding to get it to work? What other options do I have for high-output alternators?

I know where I can get an alternator from a 97 chevy with a 350. Would that bolt straight on with this bracket?

 

No idea, I'm not Trail Gear.

 

Several threads on here if you search about alternators...

And check the usual suspects. LC Engineering comes to mind...

 

whats the fuse rating on the amp? what size wire do you plan to run to it?

 

I actually ended up going with 2 1600 watt amps. They have 2 40 amp fuses each. Im running 2 KnuKonceptz KCA 4 gauge wiring kits with 80 amp fuses plus a Big 3 upgrade.
