Selecting a HO alternator

well whats with the huge price difference between db electrical, places like power bastards, and then EA and DC and Ohio gen?

where does the big tag come from?

I can't speak for other companies, but the DC alternator I bought last year has been a great product.

My RAV4 alt started as a Denso HO alt for a 4Runner V6. Swapped the pulley and the rectifier/regulator circuits. It fit perfectly and there was no wiring to do. I'm able to power my competition system almost exclusively using alternator power (so I stay at 14 V during the runs).

As others have mentioned, it's a little more expensive and takes a couple weeks to deliver. They do start with a new product and add to it, rather than remanufacture old ones (replace brushes, circuitry, grease the bearings, and clean the terminal).

It has developed a light squeak in a year's time... but considering how hard I push it, that's not bad.

Anyone else think it's not necessary with 600w worth of subs lol?

But if you're going to the an HO, DC power has been great if you can wait for their build time.

Mechman, Ohio Gen, PB all seem to be nice

It doesnt really matter how many subs he has, it depends on what amplfier(s) he is running.

I would invest in a 2nd battery before an ho alt.

well wouldnt dual batteries only really be good if i wanted to run the subs with the car off? i mean the alternator is what supplies all the power for the vehicle while its running

yes it would but having another battery can take a lot of stress off your alt. you shouldn't be having much voltage drop at all. have you done the big 3? you may also have an electrical short somewhere.

batteries arent cheap either.... i havnt done the big 3 but plan to. where could i be having an electrical short?
