gdipilato Posted October 3, 2011 Report Share Posted October 3, 2011 i have had a rockford fosgate prime r500.1 for a few months now. it has been a great amp. all of a sudden one night i got into my car and there was no sub power no power light or protect light. checked fuses found they were blown replaced them and everytime the amp would turn on the fuses would just keep blowing. i noticed whenever i replaced the negative battery cable back on the amp it wasnt sparking whick i thought was odd so i checked the ground. as far as im concerned its exactly how it was 3 months ago. the ground wire is under the seat belt bracket. i sanded both contact sides down and put the wire in between it. i repositioned and sanded a little more and tightened it down real good when i put the wire on the amp it was now sparking a little when i went to put it on. but i also heard sort of like a fizzling sound coming from the amp and a little bit of smoke. i wasnt really sure what to think but hey the fuses didnt blow so i turned the key on and all hell broke loose. the amp littlerally puffed out smoke it was quite the show. by the time i got the battery cable off the whole car was full of smoke. what happened. everything was working so good? the amp has a 1 year warranty so i hope its covered. maybe i should have been removing the positive terminal not the negative. i just cant see how anything i could have done could have caused this. i had the right fuses on the amp and also have a inline fuse in the engine compartment.

kickass audio Posted October 3, 2011 Report Share Posted October 3, 2011 First of all it sounds like a poor ground. Grounding to your seat belt bracket is NOT a good grounding spot. A better grounding spot would be a bolt off your strut tower, luggage tie down bolt, or frame. I highly doubt they will cover your amp since its smoked, you should have sent it in or had a professional shop look at the amp and see what they thought of it. If i saw someone grounding to the seat belt bolt i would not cover their product at all. It may be that you crossed a wire on the amp by removing and re-installing the ground wire on the amp so many times. They are not made so you can remove and re-install the amp several times. They are made to be installed and left alone. The more you take the wires in and out the more fragments of wire break off from the screw coming down on the wire and if just one tiny piece of wire crosses a contact between your positive and negative it will spark a fire. No offense and im not trying to bash you but you should have stopped after blowing the first few fuses and asked us for help.

Is it possible you mixed up which terminal your ground went to? I did that once (and never will again haha) and luckily my fuses took the hit (actually melted one of 'em) Sometime when you get distracted with other things you end up not paying attention to the connections...

gdipilato Posted October 3, 2011 Author Report Share Posted October 3, 2011 was the amp mounted tightly? Wires neat and no bare wires? the amp was not mounted but i never really had a problem with it moving around too much ( the box kinda wedged it up againt the back seat) and besides i have good terminals on the end of the speaker wire so any positive to negative contact wasnt really too much of a concern. also since installing this is the first time ever disconnnecting the amp from power. i do agree the whole seatbelt thing is not the best but it did work flawlessly for 3 months. i never even had the gain more than 75%. i guess thats why i think its strange. i think the only thing that could have happened is something rolled around in the trunk and somehow bridged the positive and negative terminal or maybe its just bad luck. thanks for all the responces. i guess im off to buy a new amp. i wanna hear my 2 jl 12w0v3s Quote Link to comment Share on other sites More sharing options...

MrSkippyJ Posted October 3, 2011 Report Share Posted October 3, 2011 Mount your amp, get a better ground, stop in hooking your connections, set your gain correctly, stop using bass boost, and just use the same amp to run both JL 12s. Ps, if you keep replacing blown fuses that should be an indication something isn't right. I'm not sure what kind of spark you were looking for but I don't know of any spark that is good.

kickass audio Posted October 3, 2011 Report Share Posted October 3, 2011 The only amps I know that sparked were my high powered amps like the one I have now and my previous sub amps. They have a really quick spark when you put the fuse in because its charging the caps up but even then it isn't always a sign its right because the same amp that sparked the first time I put the fuse in, didn't spark the next time I put it in.
