[QUOTE="cl0udnyn3, post: 8168684, member: 657062"] Ok so I have a 1993 Toyota Corolla with the 1.8L 7aFe. It has an aftermarket beefier alternator that I had tested and puts out 40 - 50 more Amps that the stock one. I have a Duralast battery thats rated at 700CCA and have also tested this and its in good working condition. All my wiring for my amp is 6 gauge directly from battery. I have 2ga wire from ground to my strut tower and my amp is body grounded in the rear. I put my power prob and multimeter on both and they are very solid grounds. So here's my problem, my Amp or Sub or SOMETHING isn't right with my system. The amp cuts on when its supposed to, I'm getting 14.8v at the amp when the car is idling, but its like it's not even trying to push sound to the sub. So rather than bore you, here's a list of everything I've checked so far. - Checked head unit, it produces 13 - 15 mV at the RCA jacks. - Checked ALL wiring, everything is good. - Checked my RCA cables, 0 resistance. - Checked my grounds, and they are good. - Checked my battery voltage while car is on, its 14.8 at idle. - checked my terminals on the amp and voltage at amp. Thats good. - Checked resistance of sub, that's good. Thats about it. I don't know what else to test -_-' Oh and btw the Amp is a Jensen 500wt dual channel. The sub is a 12" clarion. So my car should be able to push the sub even at a lowered setting, but like i said it aint doin ****. Any help is greatly appreciated.
