The question is can the 90 Ampere Fiero alternator support 2 stereo amplifiers? I have a 60W x 2 @ 4 Ohms amplifier. In the past I have run all 4 of the Fiero's speakers (front 4x10's, rear 4x6's both 4 Ohms) off one 2 channel amp. This worked, but I lost front to back fade control which also affected the depth of the music. I was wondering if I can successfuly add another of the same amp to the car using the stock alternator? I realize there are 4 channel amps out there, but I can pick up another 2 channel amp a lot cheaper. I may still upgrade to a 4 channel amp, but I'm curious about adding a second amp. Thanks!

They are not super power amps, so it should work fine. Make sure they are wired properly ect... If you do experience any dimming lights or whatever a .5 farad capacitor should solve the problems.

90 amp alternator can support up to about 30 amps RMS of service to audio amplifiers without taxing the rest of the system. With 2 60X2 amps or 1 60X4 amp your only drawing 16 amps max. and 12.5 amps RMS. I'm running a 75X4 and a 200X1 Which is drawing about 24 amps RMS.
Make sure your using an 8 gauge wire for power and ground.

i'm running a mtx 1000d amp and it hits hard with no loss in power...one thing to remember if you use alot of power ,,,as in bass you might want to get a cap so you never have a volt drop when it hits

i agree with red wolf if you notice and drop in voltage then it would be best to use a cap to support the system

i third the cap idea. what a difference it makes - the first time i got one ( different car) i noticed the car lights flickering w/ the bass - so I put the cap in to stop that, but what a difference it made it the sound, much cleaner bass.
