3500 watts?  A 350 amp alternator and 0 gage from the alt to the battery and from the battery to the amp disrtibution block.  Also fuse it at 350 amps at the battery, run 0 gage for main amp ground and upgrade your engine ground strap.  Cheers.

Ahhh, a loaded arsenal and no battle plan. Use a fused distro block to split power out to the 3 amps.  Wire one cap in-line on the power wire after the distro block to each sub amp, with the caps close to their respective amplifiers.

And just 398 more opinions to come...

I doubt you'll be able to.  And it's 350 AMPS, not watts. You might consider a dual 180-200 amp alternator setup.

the r's are only 300 rms each x 4 =1200rms  but can take a little more from what i hear...i would just get 1 fosgate 1501d if i were you...1600+ rms at 2 ohm

are the r's 2 or 4 ohm..?

if they are dual 4 each then i'd wire them series / parrelel to get a 2 ohm load..

and if you insist on getting those mtx's you will not be using much of  them cause they will only be putting out 750 rms ar 4 ohm..

now if they are 2 ohm get a 1 ohm stable amp..and wire them series / parelell

if you stick with 1 amp you will be better off.. Your alternator and wallet will feel better if you choose to do 1 instead of 2 mtx's

i do own the 1501d mtx and am sorta satisfied with it..but i wish i had gotten the fosgate.it has alot more features and imo putts out more power..also has a ssf , wich is a must if runnin ported!

give me the specifics and i'll help you out

p.s.you wont need to upgrade your alt if you only use 1 amp..you can get a optima bat and do the big 3 and you should beable to get away with it.imo
