I have two jp63s and I sent both in for repairs on caps and one amp was sent back with more damages and now my bluetooth bass knobs don't work they both are stuck on scan for one amp ill have to check my other amp tomorrow and see if it does the same thing after paying so much for the amps and both blow caps with in a week not even bumping hard then sent both out for repairs and they took 4 months to fix, bad customer service hard to get in contact with them at times and now this, it was not worth the money for all this trouble and headaches
