MTX Thunder x502 Red light

SOURCE: MTX Thunder problem

Make sure that your connection at the battery is still good-sometimes the wire corrodes up front when your system is installed for a long time-so check that out and of course the fuse that you installed a foot away from the battery so that you dont burn your vehicle down if a short occurs somewhere down the line

if the lights on and there is no sound it's either a cd player issue or your rca issue or the inputs for rca's on the amp are no good. or you have your subs wired at a wrong load to your amp and it is in a constant protection to avoid burning up.

is supposed to be green, maybe it is protected
if so you have to do is remove the jumper will be, and
for about 10 seconds and then put it back
or reset to remove the protection.
does not work now if what happened is that the channel hit
that as wrong?. because they put the speaker cables if invented
positive that should be negative. I hope you
help that you are well
