Default system killing altinator?

ok so i have a 1600 watt rms sub amp. and a 640 component amp and a 3 farad CAP

and the alt is basicly dying. typical light dim and the alt tends to drop to 10amps and this is while driving.

any ideas?

i was thinking about putting a smaller pully on the ALT. is this a bad idea?

i have not upgraded the wire to the bat or the alt to a larger gauge. may be more work then its worth.

i was also thinking about getting a larger ALT. but its already a 140amp ALT.

not looking to spend a whole lot of money to render the problem. but i would like to try to fix it.

Yes, the 140amp probably can't handle all that.

Upgrade to a 160amp.

Also, you should upgrade the wire when you upgrade the alt.

actually to be frank with you, 1600 watts should not be killing your alt. Even with your 640 watts componet amp. Instead of upgrading your alt, I would suggest you buy another battery to help your voltage out. What amp and sub combo do you have by the way? Take a look into maybe a kenetik 2400 or a powermaster 2400. Both are great products and will help greatly on your voltage drop.
