Contour Enthusiasts Group Archives Forums Modifications Audio Will stock alternator be ok

this is what I've got,
Crossfire 1000w class d
PPI 125X2
DEI 75X2
red top
1f cap
Should I be ok or should I maybe drop the 75x2 & run the rears Off the HU.

I would get another 1 farad or better cap.

In my own opinion, i would say that your alternator shoud be totally fine. I've got "2" 300 watt amps, and a 1000 watt amp. I've had this setup for about 2 years now. Also, have you changed your battery ground wire to about 4ga? Hope this all helps

This is just my opinion, and you should take it at that...
I would remove rear speakers from the system altogether...

The only reason I would have them is if you have kids in the car a lot and play music for them.
Otherwise, you have a system 99% for driver's listening pleasure only.

yep... and your alternator will be fine...

Bigger battery ground wire , maybe another 1 farad or one 5 , relocate (2) batteries to the trunk I would guess ~ how many amps are our alternators anyway ? 80 , 90 amps?

actually, the contours stock alternator is 130, yes 130 amps. thats HUGE.
in fact, i think i remember hearing that other than police interceptors who have a slightly upgraded alternator, its the biggest ford produces. i believe it has something to do with mass production, and for sharing many parts, for example contour alternators with trucks, etc.

one possibility is that the alternator is performing fine, but the battery wires, such as the 12 v and the ground, are not able to transfer the current to the battery quickly enough. upgrading those would be definitely cheaper, and may fix everything

but no, i have 1000 watts peak and my lights only dim if i pump up the volume for some heavy bass, if you wanted a cap, though, it couldnt hurt, i personally just dont have one
