Question about Infinity Reference 7541a Car Audio Amplifier
I just installed my infinity reference 7541a amp with 4 sets of kappa perfect components. i was doing a road test for sound, though not excessively loud as to not DAMAGE THE @#(*$&@! EQUIPMENT, and suddenly everything went quiet. the i had the input levels at maybe 2/3, far from the whole load. didn't help apparently. now, the led's cycle between 'clip' and 'protect' whenever i attempt to turn on the car with the amplifier's turn on lead still connected. the amp felt pretty hot when i got it turned off, even though it had plenty of ventilation room. probably melted something, and if i did im going to be pretty steamed. the amp was running for all of 30-45 minutes, mostly at a really really low volume. when i read the manual, it said that the light sequence corresponds to DC voltage on the output, and that it probably needs to be servies already. i'd rather do it myself if it's an easy fix, after spending so much on my car i don't want to fork out more money for a repair guy. any possible solutions?
Try first to disconnect all of the speakers on the amp. See if the amp will turn on now. If not , the amp has bad output devices, or drivers, and or the switch mode power supply is fried. There is no easy fix with solid state elctronics as there are no user serviceable parts inside. The units going to need to be repaired by a service tech unless you know how to solder, unsolder, test mosfets, transistors, and diodes as well as resistor.
