My amp was working fine and now when i turn the car on the amp turns on for 2 seconds then turns back off i tried fixing the ground but that wasnt it
got a fusion powerplant.. same problem.. comes on then turns off after 2 seconds.. have completely re-wired car and still doesnt help! could this be an issue with wiring on the car itself?
You'll have to remember to turn it off afterwards, but u can also run a power wire directly from the battery to a toggle switch to run your amp. u can turn it on and off at will and it will bypass any problems that your current one may have. just mount the switch in you dash somewhere or in a console if you have one
Sounds like remote turn on wire is bad. If using aftermarket HU, find another location to power amp. Try the the power antenna wire on the HU to run the REM.

make sure ground is good then turn gain all the way down turn on deck turn it all the way up then turn it off then back on agian its like a jump start the amp then should work and you can reset all youre levels
hi there
few steps to try
1) try grounding amp to a new location
(make sure the amp is grounded by itself)
2) check the power wire from the battery to the amp
3) if the 2 steps don't solve the problem try turning your amp settings down and disconnect the power wire from the amp after a few seconds reconnect the power wire and amp should reset itself.........
if this doesn't work let me know there are other tricks that can be done but these are the most common firsts to be tested (also make sure the ground wire is larger than the power wire)
hope this helps
add doide from the battery to the unit, 2 doide should help that.
1 connected to the positive, an 1 connected to the negative. 5-10 amperes is ok. check for the polarity. and try to take off the ground of the unit then try it.
if its turning on and off then it could be one of three things. 1, the power cable has a faulty connection to the battry, 2, the fuse is either blown or not big enough for the output needed or 3, the remote lead isnt connected properly to the head unit.
wouldn't be the first JL amp I saw fried...but there are some tests you can do. First of all, double check your fuses, they may appear to be fine, but sometimes they are blown even if you can't see it. Either blindly change them or test them for continuity with a digital multimeter. Also, disconnect the remote turnon and jump power directly over from the power wire to the remote terminal on the amp, if the amp powers on then you have to go double check your remote wire. Hope this helps.
heyman... try checking the fuses on both the sony amps. if they are ogood...next try hooking up each amp individually...if they will turn on seperatly but not at the same time it could be due to over abuse of the single ground and power leads that feed your amps. meaning that whie 2 amps will draw more power, they will also break down the wires faster. a continuity test of the power and groundwires should also be done.
try using a better ground. while new cars are great, they also have more paint and plastic in the works...so finding a good ground for your amp to run off of isnt always easy. you can try running a gbround cable straight to the negative terminal of your battery to test the amp, poor grounding is the most comon cause of amp failure. ps,the fan may be staying on as a protective service, as if your amp loses ground whenpowered up it will keep the cicuit boardfrom heating up on voltage surges.
Have you checked the voltage on the head unit's remote turn on lead?
