I've got a 2005 Grandprix, not supercharged. Apparently i can put another alternator in its place. Did anyone do this? I need it to run my 5000 rms because my cap says the voltage goes down to 10v even while driving. I really don't know anything about mounting or wiring in a second alternator so any help would be appreciated, thanks

dont think u need dual alts for what u have..
a good high output alt with some good batts is all u will need
can order trhrough the canadian distro canadian auto electric (416-299-7337) in scarborough

these are rated as the caddilac of batteries. they make the stinger. are the original creator of optima. these things from what i have read are tough to kill.
i have 2 in my truck now one still has to be connected but will be very soon, still working on the wiring for it.

what ever way u choose to go, good luck

Have you done BIG 3 in 1/0? Another good idea is to run a dedicated ground from amps to batt's if you haven't already

I doing 0/1 gauge later today and adding an amp to my door speakers. Thanks

And what do you mean? I have separate grounds x 3.
1 for the amp, 1- batt, 1 -cap

there is a sticky on the big 3 in the 'general discussion' section of the forum, this will allow the system to get the power from the alternator and battery to the stereo

Gee good choice as only the rarest car has extra alternators, not cheep, not easy and not needed for you
