hello, I have a 94 volvo 850, with a aftermarket stereo system in it and. i am getting flashing headlights and interior lights at higher volumes. I have put a audio capacitor in, and upgraded the alternator/ground wiring in the car to 1/0 gauge.. and still have flashing lights, that tells me i need to upgrade the alternator. it is a stock 100amp alt.. and the problem i have is i cant find a high output anywhere.. does any one know where i can find one.. or one that will fit.. with little modification. also if i do find one what else will i need? will i need a new rectifier? or any other upgrades?
