I've tried a buncha stuff, but i still have a problem-

Car is a 1990 Talon

New belts

Battery relocated to trunk

4 gauge wire From alternator terminal to wire that goes into distribution block

4 Gauge wire from Distribution block to battery

4 Gauge battery to ground

All of the following is a daisy chained ground, crimped and soldered-

4 gauge from front upper motor support to shock tower, 8 gauge to intake mani, from intake mani, 8 gauge to firewall, and 8 gauge to bolt on transmission, 4 gauge from bolt to P/S frame rail, and 8 gauge from frame rail to cam sensor.

Car makes 14.4 volts at battery at idle, with no load.

If i put the headlights on, and the stock electric fan on, the car's idle would drop to 5-600, and makes moving from a stop a real SOB.

Any suggestions as to what this problem could be?

I don't want to install my system till i get this problem figured out, right now there is no speakers, just a HU.

Sounds like a dying alternator, or even a weakening battery.

Do you have a Kragens (or Checker / Schucks) or Autozone near you?

You can drive to one of those and they will have someone come out to your car and put a diagnostic meter on your battery to see if the alternator or battery is going bad on you.

Its free too (at least it was at the Kragens here).

I agree with last poster.

and...

Maybe your idle is too low?

Idle is about 800, give or take 50, no load, with timing at 5*BTDC, per the emissions sticker.

Once you put on the headlights, you can hear the engine load up, and when you have the turn signal on, you can hear the fuel pump change pitch with each flash.
