fuse keeps blowing, MTX 1501

main reason why i asked you about the power wire is because mtx's are very touchy...i've dealt with them a lot...while certain things are important for all amplifiers they are essential for longevity with mtx, especially the 1501D...you need to have at least 4 Guage all the way back, not split into 8 at a distribution block or anything...ground needs to be perfect...and NEVER...EVER...make any adjustments to the amp while it is on...no changing the gain, crossover, or boost...if you have ever done any of these things...you no longer have to guess why you are have a problem...and by the way...when the 1501 D's blow...they blow big and are usually followed by other problems...my advice...take it out of you car, so it is no longer hooked up to any of your other components like radio and subs that can be damaged...take into a shop somewhere and pay them 20 bucks to test it on their bench...you can do this at small shops or circuit city or best buy...it takes only minutes and may save you from doing damage to anything else in your system

Have you tested the power wire, ground and remote turn on lead for possible shorts ? Did your ground wire some how come loose ? Try taking this amp out of the car and reinstalling it into one of your buddies car's and see if it blows fuses too. Your not hurting anything if the fuse blows, that's why there's a fuse inline.

if you hook it up in one of your buddies vehicles make sure that you can afford to pay for there radio or their subs...because anytime you hook up a bad amp to a system problems can occur...true the power wire has and in-line fuse so your power wire or your car will not be harmed...but there is nothing prevent the wear and tear of bad signal or the wrong signal repeatedly if it keeps blowing fuses...by the way...anytime you buy an mtx amp you also get a 3yr manufacturers warranty instead of your average 1 yr...do not be discouraged too much if it is blown...i have seen mtx take care of many people in your same situation

And what do you think a cap would have to do with anything?  If by "+ and -" you mean main power and ground, then your amp is most likely toast.  Sorry.
