QuestionI have had an amplifier (Boss 300W) for a few years now and decided that I needed a higher watt amp, as my hearing is apparently dulling.
I bought a 600W Kenwood 4 channel and bridged to a pair of 10's. Worked great for a couple months, then one day the amp shut off. It still had the power light, but no sound to subs, only peripherals.
I thought I must have blown the amp and bought a Sony Xplod 600W to replace it.
When I installed it, the power protect light was on as soon as I turned the key, and of course would not play through the amp. I have checked all my wires (even disconnected all, inspected and reconnected all wires). I then bought a 200W cheapy thinking maybe the 600W was too much of a load on my battery. Same issue, the protect light comes on.
Please HELP! I am beginning to think I am doomed to listen to 50W split 4 ways forever!
Answerusually the protect light will trigger instantly if one of the speaker wires is grounded against the body of the car or a negative somewhere. if the wires that go to your sub box go underneath the box or are tight somewhere, there a chance that they've rubbed through the insulation and are grounded out against the body. check for all that stuff.
one easy test is hook the amp up with ONLY the 2 main power wires and the remote wire, no speaker wires and no RCA wires and see if it still goes to protect. most likely it will not. leave it on and carefully start connecting the speaker wires and if you connect one that makes it shut off then you've found your short. if you get them all connected and it still doesnt go to protect, then pop your RCAs in and see if that does it.
good luck!!! Let me know how it goes and if we have troubble getting it going I'll give you my email address so we can go back and forth a little faster and maybe do some photos or something if nessesary. Dont worry! we'll make it work!
