I was told that i can put a high output 170amp-200amp altenator in to run all the things i have in my marauder. I'm on my 3rd altenator within 1 1/2 yrs, good thing i got that warranty when i got the car. Had to take my subs out until figured out what to do, no bass and it sucks.

Have you done a wire upgrade from the alternator post to the power distribution block yet?
Are you buying OEM alternators or lifetime warranty JUNK from FLAPS?

I just installed a NEW 250amp DB Electrical alternator (no pulley clutch). I also upgraded the stock wires (from alternator to battery, from battery to ground & from ground to engine) with 2ga wire.
Alternator:
New battery terminals:
Engine to ground wire:
Alternator to battery:
More alternator to battery & negative battery cable:
Also added a battery tender:

250 amps in a tiny 4g case is a ticking time bomb, especially with ZERO clearance in the back of the alternator for cooling...where the most important component is located (the bridge rectifier)

Geez! So, do you use that setup to power your flux capacitor? That looks nice!

I found I get lower charging volts at idle with my DB 250 amp and get a squeel after hard acceleration. I am thinking of going back to stock.
That GM guy....
My old Galant did that, pretty sure that's from the pulley not being clutched. I may also not be understanding the scenario you're doing this in though.

No squeal with mine and it charges at 14.2 - 14.6.

I'd do the wiring upgrade first.

Man that engine bay is sweet!!!!! Props Jim on a clean setup.

Lower idle output is a common issue with many alternators that have been modified to put out more than the max OE for the design series. Shorter life is not uncommon either, if the alternator is frequently called upon to deliver it's full output.
What is the source of the alternators that are failing. Most of the ones available at you FLAPS have not been rebuilt, they have been repaired, cleaning them and only replacing the part that had failed.
NAPA does offer some 100% new alternators, not likely for our application though. The other good option is to find a good old school Mom & Pop local electrical re-builder. That clutch pulley may throw them for a loop though.

Wiring upgrade was done #2 welding cable. My battery is in the trunk though. Never has a problem though when I had the factory alternator.
