Now that i will be dropping 2 SA-15 sub in my 1999 plymouth breeze (a just for fun build, nothing serious), I probably should up grade my alt because im gonna be running about 4000w total (includes speaker, subs, leds, and maybe HID's, ect.). so my question is what alternator would be good and fit this outcast from the audio world car? I can get one from mechman but its $600 for just a 260 amp alt. so is their any cheaper anyone can find?
