[QUOTE="akheathen, post: 7446991, member: 629234"] lol, so the guy sold you a kicker amp, installed it, then told you it was a junk brand and tried to sell you some more junk...... no, that amp is just about the same amp as all the other normally decent amps out there, not cheap, not junk, but not high end sq/powerhouses that cost 5x as much. it's not because the amp is junk, the amp is actualy trying to tell you something. here is what you do- get a digital multi-meter. start with your battery voltage (dc) as a reference. now, go measure the voltage at the amp. it should be pretty much the same. now turn the amp on and measure both again. should be pretty close, possibly .2v off typically, but not more. if not, you have a problem. leave the negative terminal of the dmm on the grond at the amp, and check the voltage of the remote wire and the power wire alternately. if they are not the same, then you have a connection problem with the lower reading one. if they are the same, butlow, you have a bad ground somewhere. also, set your dmm to ohms (if it has range, set to the lowest, loke "0-200" or something like that) and touch the probes together, what it reads, (probably .02-.4 from what i've seen) and you will need to subtract that from any reading you get on ohms. now, unhook the speaker wires from the amp, or the back of the box, and see what they read. should say about 2, or 8 ohms, +/- >1ohm... if you get a weird reading, then you may have a bad coil, and need to pull the speaker and check each coil. if it reads 4ohms, then you have a bad coil, or tinsel lead on the sub, or they left one disconnected (both of which has the small possibility of shorting the speaker wires) if they wired it wrong, then i would go back, yell at them, adn demand a refund for the "work" they just did.... only running 1 coil will damage a speaker, and they did not actually troubleshoot the problem, or they would have a better answer than "kicker *****" [/QUOTE]
