my stereo is sucking up way too much juice! alpine 9833... since alpine uses the same wire harness for almost ALL of their non-lcd HU's, installing it was no big deal. just unscrew unplug and then plug in and screw in. anyways, when i turn up the volume and such (w/o my sub and amp powered) it sounds like total crap, and my lights dim. if i plug in the sub and amp, the subs barely even make noise and when they do it sounds like total ass. for wiring im running a 4ga power and ground to the amp, and 12ga comes with the alpine for constant, ground, and memory. if i swap the alpine 7894, everything is like it was. sweet. loud. ear popping. im running a 90A alternator. i had a 120A in the car previously from my mirage but it went due to old age. could this be it? im not thinking i need a cap. should i run a direct line to the battery for constant power? right now its not attached to the radio harness, but to my clock harness. the wires to the clock are thicker than the ones going to the radio. i have no clock anyways. should i change my ground? im grounded to one of the screws that hold the radio cage in. if you guys need pics to see what i mean, let me know. i want to get this solved quickly. while i have good tunes, i want good sound also.
