the other night my amplifier shut off, although there is power to it it is not outputting any sound to the subs, all the fuses are ok. does anyone have any ideas?
check rca's. check speaker wires. make sure they're all connected firmly, no shorts or anything.
if everthing checks out fine, grab a DMM. first use the ohmeter to check if yer subs are blown. if they are fine, test amp's speaker terminals for voltage while the radio is on. if you don't get any signal, unplug RCAs from amp and test voltage at the tips while yer radio is playing. if you get no signal, you may have bad RCAs. so test for voltage at preout tips at back of radio. if you get signal, you need new RCAs, if you get no signal, yer deck's preouts have gone out. hope things turn out well.
