Hey guys, first post here with hope that you may be able to help me with a problem... Over the past week, my battery has been I guess coming disconnected whenever I start my car, which I think is from the amp power line not fitting with my current battery connector on to the terminal. Anyhow, I have to wiggle and jiggle them around a bit before my car will even start... Even after this, sometimes the amp cuts in and out while driving. When I got off work, I bought one of those battery terminal cleaners hoping that it would result in a better connection, but it didn't help any. I went to the trunk to find the power line for my amp not plugged into the amp. I started to screw it in without disconnecting the battery (it was 5 in the morning, stupid me) and a bunch of sparks flew out from where my screwdriver was screwing the screw in place to hold the power line. Anyhow, in short, is my amp fried? I do not get any sound out of my sub, nor are any of the LED's coming on. I checked the 2 fuses and neither of them are blown, I smelled the amp itself to see if it smelled like burnt electronics which it didn't. If it's not, what do I need to do to attempt to fix it? Thanks for the help in advance guys.
Double check your fuses!!!! I have seen fuses that look good but, are not many times. Use a test light or VOM. Once you are sure that you have 12 volts all the way back to and at the amp, check your remote turn on wire for operation, it should show 12 volts whenver the radio is turned on. If it does not, some radios have a fuse on the turn on lead and it may be blown, you may have shorted the power wire over to the turn on lead and back fed voltage to the radio and blowna fuse. Also be sure your ground connection is in good condition, if it was a weak or poor connection, the high currnet from the arc of the short may have made it even worse. Shorting out power wires is not a good thing, but it should not hurt your amp in any way unless you happened to short out something you didnt see beins how it was early in the morning!
update- i had a look at it again today before i went into work. i ended up replacing the fuses with no luck in getting it working. i checked my ground wire, and it looked fine, but i went ahead and undid the bolt and nut it was on, then wrenched it down again. the amp turned on, but the sub sounded blown, is there any way that short could've blown the sub? i hooked up my roommates 15" and it didn't work at all. i could very faintly here bass coming through it, but i had to have my ear right next to it. i had another friend of mine come over with his box with two 12"'s in it. they worked somewhat, but i had to have the volume up at a ridiculous level for the bass to even hit. fast forward 2 hours, i hooked my original sub back up, and it started working (but still sounded blown), before I could put the car in drive, it cut out again. i got out and looked at my amp (it's in my trunk) and the protection (red) LED was on... coming home from work, it worked, but only if I turned my bass on my head unit all the way up to +6, and cranked the volume up on my iPod up to about 85% (i connect my ipod via tape deck). do you guys have any idea on what's going on? or should I just look for a new sub and/or amp? thanks for all your help guys it really is appreciated **my sub only sounds blown when the trunk is open. if i close my trunk, it doesn't sound blown at all (that I can tell at least, I am not an audiophille by any sorts..... yet). i don't know if this has any relevance to anything, but I thought i'd let you guys know. *edit* I reread your post The Viking, later on today when I wake up, I will check the remote wire coming from my head unit for a fuse. I will update once I find out if anything looks suspicious.
its not your remote wire, the amp is turning on, its just going into protect. sounds like you blew your subwoofer and it took out your amp. sometimes the protection circuits in amps arent fast enough to actually save the amp from harm when you blow a speaker. tough luck. i would get a digital multimeter and check the voltage at the amp to be sure you are getting the proper voltage, but it sounds like your amp is blown to me.
