bullcrap... personally, I ran more power than that in a 1968 Mercedes
with a stock THIRTY FIVE amp alternator without ever seeing those
symptoms. Granted, I put in a larger than stock battery and improved the
cabling throughout, but it worked fine for a couple of years before I
went with the big 140A Delco.

Rich Clark wrote a very good piece on this subject a few yeas ago,
keeping in mind this is a guy that helped start the capacitor hype... he
was running a couple of the biggest MTX class AB amps in a stock
electrical system, metered it with some expensive lab gear and the
bottom line was the car was quite stable with that much power on the
stock charging system.

The mechanic is right!

The alternator has to provide enough amperage to power your car's entire
electrical system, charge the battery, then feed your amp. Most replacement
alternators only provide sufficient power to support the vehicle's OEM
needs, with little left for a slammin' system...

You need a larger (amperage-wise) alternator and/or a 1F (or larger!)
stiffening capacitor...

I am on my 4th alternator in my 1991 Integra.
Napa autocare service centers are replacing them, under warranty, until


now.


They referred me to an auto-electric shop. This shop claims that my car's
wiring is fine but the amplifier in my car is responsible for destroying


the


Napa alternators.

I have an Alpine MRD-F752 5ch (75wx4 and 250wx1) driving 4 PA DX6's and a


JL


Audio 12".

The mechanic at the auto-elec shop claims that he tested the amp and it is
drawing between 50-80 amps!! This is a 60amp rated alternator so with the
lights and A/C, etc..he claims the stereo is pushing it over the edge.

Wait a minute...Watts divided by volts= amps.
325w / 12v = 27amps..right?

Why would that Alpine be reading so high?

Why do my headlight dim with the bass note thumps even when not blasting?

I think it is a Napa alternator issue...as in junk.

I have to call them in the morning and let them know if I am going to


remove


the amplifier. Damn I'd hate to do that it sounds so sweet.

WTF can I do? I am scrambling for electrical answers I know little of.

Why do my friends, in little Honda Civics and other vehicles, have no
problems driving 500 watts with the stock alternators?

Thanks
