I'm new here but not to cars. I'm normally post on SoCalPrelude.com but I do browse honda-tech every now and them. Anyway, I wanted to know if anyone can recommend a high-output alternator for the Prelude. I drive a blue manual 5th gen with a lot of electronics. I have about a 1600watt rms audio system, a gaming computer with a 750watt power inverter, PS2, and a few other things too. All this is running off my stock alternator right now and an Optima yellow top (relocated to the trunk). I plan to get a second yellow top eventually but I don't think the stock alternator will be sufficient. So, does anyone know of a bolt on or a custom alternator I can get? I also removed my powersteering system so I have more room in the alternator area.

 

msd sells some high output ones. they are expensive as hell but are all chrome and shiney

 

I would figure out first your amperage drawn first. stock 4th gen lude's alternator's are good up to 90-95 amps of consistant draw. but only need a fraction or so for functioning components leaving still a bit for you to use freely. Your 1600 watt stereo draws a bit when cranked and pumping out the bass, but i'd still say you'd be okay with stock alternator. Though stock is probably more money than a pretty good aftermarket one anyway! I think after stock your looking at around 150 amp alternators, but then you might have to do rewires to handle the higher currents.
do some searching on stock alternator wires/batteries to make sure they can handle 60 more probable amps.

Bosch makes a 180 amp alt, but it is ridiculously expensive.

 

well, the MSD alternators looks like they cost around $400 and i'm assuming that I need to make a custom bracket or some sort to get it to fit. I couldn't find the bosch one though. Any more ideas?

 

Powermaster makes high output alternators...

 

power steering off? I'd die without it. :/ I run a laptop in my car too, and I use an iGo adapter, and it works great.

 

just bring your stock one to a shop to have it rewound for higher output
