When you stop laughing at my misery, maybe someone could give me some suggestions! My son just upgraded to a larger amp in his Jeep. A friend of his wired it for him. I'm a fairly intelligent guy, simple job, I don't need any help...My '06 Jeep Wrangler still has the factory unit and speakers, so I figured I'd put his old amp to use. It's a MTX Thunder 240. Basically, all I wanted to do was add the amp and a single sub. I just put Pioneer speakers in the overhead boxes and would like to get a little more low end and volume to overcome the wind noise. No big deal. Three and a half days, two complete installations and removals, and a third partial install, (still under way) later...it comes down to this. I knew I had the power wired correctly. 20amp fused + from battery, grounded to bare metal on chassis, remote wire from a switched + in back of head unit. Amp comes on and goes off when it's supposed to. Good to go! However, when I hooked up the sub, 12" 4ohm, using the bridged diagram on the amp ( + L to - R) the amp just started vibrating...rapidly. So, I tried to just hook it up on the R channel. One way simply pulled the cone in, one way, pushed it out, but no sound. I have un-wired and re-wired the input wires twice to make sure I had the +R and +L ( spliced into the rear speaker wires) and both -'s together on the gnd pole. ( the wires inside the speaker boxes come from a plug and are different colors than the actual wires, and after splicing into them with black wire, I taped them all up without writing down which was which...duh) After hours...and hours of diagnosing and frustration, and finally being sure the input wires were correct, I put a voltmeter on the speaker outputs. The right channel shows nothing? And the left shows over 20 volts! The amp was working fine in my sons jeep, so what I can't seem to figure out is, 1) Is the right channel fried? and B) What fried it? So, rather than bridge it, I just hooked the sub up to the Left outputs. It works for now, but I haven't tried to set it up yet. I still have to get a box. My other question is, will the fried channel damage anything else if I use it this way for now, and how much would a repair likely be if it's just maybe a transistor? Other than all that, I've enjoyed the install, and am now thinking of redoing my whole system. Man, how well do you thing that will go...
