doughboi916 Posted September 17, 2007 Report Share Posted September 17, 2007 sup guys, im getting pissed, i did a install in a 05 300c with the stock navi, i used a LOC spliced into the rear speakers, 1 15in BL with a lighting audio amp(the good one made by RF), i wired the sub up to 1 ohm and the amp does 1000rms@ 1ohm and lots of people are telling me its underrated so it really does around 1100, but this is the second amp that bugged out?? it keeps blowing fuses as soon as i plug in the + wire, it worked for a day, pounded like crazy, the amp was getting a good 13.8-14v so its getting juice. WHY DO MY AMPS KEEP BURNING UP?? could it be cause of crappy signal from the LOC?? the last amps MOSFETS blew.?????? the gain wasn't even half way up?? please help me guys, need all the help passable Link to comment Share on other sites More sharing options...

Ray Posted September 17, 2007 Report Share Posted September 17, 2007 the batt is in the trunk. does said vehicle have the factory amplified system? boston system? Where are you grabbing the signal at? before the amp? at the factory speaker? at the factory sub? What are the wire colors? Can you see those wires going right to the sub/speaker? 2008 California state record holder 157.2 Bassrace2009 California state record holder 157.0 BassraceRollin 50's 158.7db2009 King of Cali Bassrace2009 USACi score 160.5 @ 42hz Link to comment Share on other sites More sharing options...
doughboi916 Posted September 17, 2007 Author Report Share Posted September 17, 2007 the wires im splicing into are the rear deck 6X9s, those wires are Rear Left +: Dark Green/Tan Rear Left -: Dark Green/Gray Rear Right +: Dark Green/Brown Rear Right -: Yellow/Gray and it has a Boston 6 Speaker Package so its after the stock amp, all the wiring is good, i triple checked everything and i take it back when i said the fuse blew, there all good, the amp just goes into protect.

Ray Posted September 17, 2007 Report Share Posted September 17, 2007 Its a voltage issue I'm thinking.. Not signal. So, when you say the gain wasn't half way up.. you do know that is irrelevant right. what happens when nothing is plugged into the amp except ground, 12+ batt, and rem.? no rca's and no woofer. a clipping woofer will blow the fet's in most rf amps. If I had to guess, you are over driving the woofer, and clipping the amp. 2008 California state record holder 157.2 Bassrace2009 California state record holder 157.0 BassraceRollin 50's 158.7db2009 King of Cali Bassrace2009 USACi score 160.5 @ 42hz Link to comment Share on other sites More sharing options...
