Question

My subs dont work, i changed my RCA's and subs and even a different amp,and still nothing.?

Answer 1

sounds like a bad woofers

or the  sub output of the radio is turn off

Answer 2

make sure everything is wired correctly, make sure theres a very good clean ground on the amp, make sure the remote wire is getting voltage, make sure the sub is turned ON in the head unit, and also, i had this problem, on the fuse that comes from the battery, make sure its getting 12 volts to the amp, i had a fuse go bad, (wasnt blown didnt look blown looked normal, but it wasnt letting any power through) make sure to check that make sure theres power on both sides, make sure the protect light isnt comin on in the amp, pretty much check every connection and everything that ffeeds power, if the amp comes on, check the wiring on your subs, or the RCA cables and make sure they are on the amps INPUT and not output, make sure the filter is set to LPF and the input volume is up and the frequency is right, that's the only things that could really be wrong.... if you check all those and it still dont work, well, i dont know how it couldnt work if all that is right, unless the amp is bad, its coming on and not sending a signal. but it really sounds like a power issue or wiring issue,

Answer 3

check your remote wire on the back of your headunit. use a voltage meter and with the car on the remote wire should be getting 14.4 volts. it its not getting power your amp will not turn on. if the remote wire has power and still not turning on, check your ground on your amp. try running a ground directly off the negative terminal of your battery to make sure you have a good ground. hope this helps.
