I have a kicker 850.2..had it reinstalled in my new car (2001 nissan pathfinder) along with a 600.4 alpine (wired to component and 2-way type-r's) all wired to a 5 farad cap. the cap and alpine still work fine..but for some reason my kicker won't turn on..the fuses in the amp are fine and so is the one connected to the battery..i checked the connections on the amp with my voltmeter and they're putting out 14v..the ground is well grounded too..what's wrong with it? any suggestions?

Also:

Lately my cap has only been turning on 1 out of every 2 or 3 times and sometimes beeps when the car starts (a noise that supposedly indicates going below 10v or over 17v, but the lowest and higest i've seen it on start up and running is anywhere between 12.6 and 14.2). do i need to discharge and charge again?

the kicker had been working, but two days ago it stopped..i checked connections and when i pushed my seat back into place(amps are installed on the back of my seats) the 850.2 kicked back on and i decided to think nothing of it..then today when i started my car i realized i had no bass and it hasn't been working since.

i checked everything with the voltmeter..all terminals..all fuses..and i have a feeling that my other amp wouldn't work if the cap was the problem.

my protection light isn't on.

Does the amp turn on at all? did you meter your remote turn on wire going to the amp that isent working properly? It could be a number of things. Ground, Power, remote wire or maybe a fuse. Since you said you checked your gound and your power wire it is probably one of the other 2 issuse. If not then you have more serious issues. meter your remote wire and check your fuses and let us know what you find out.

With the system turned on, check voltage at the power and ground terminals of the amp that does not come on. Do not ground your meter to the chassis of the vehicle, black lead to the actual ground terminal of the amp, red lead to the power input terminal of the amp. The system must be on while checking this.

What was the voltage between the 2 terminals with the car running? also you may want to try to connect the amp that isnet working to the power, ground, and remote of the other amp that is working. See then if your amp with the problems turns on.. If it does then you know it is something with your wiring to that amp. if not it may be a problem with the amp itself.

14.04-14.07 and i'll have to switch the amps and try that when i get a little bit more time. i was hoping i wouldn't have to take them off the seats, but if that's what it takes to figure out the problem then so be it. lol

Well try this first. Since we know you have a good power supply going to that amp take a small peice of speaker wire, connect one end to the power terminal of the amp then the other end of the wire to the remote terminal of the amp. It should power up without a problem. If not then it is likely your amp. if it does then it is your remote wire comming from your headunit that is giving you the problems for that amp.

I had the same problem, it would go out, then work and finally went out and did not come back on, I tested the remote and it was putting out, and when checked the fuse it was good on the direct power cable. I tested the direct power cable and found that I had power to the fuse but not beyond. (used a paperclip), so I replaced the fuse (that seemed to be still good) . It worked and has since, so I broke open the bad fuse and found that the solder connection on the inside of the fuse had broke and lost contact (way up under the cap where you cannot see), kinda wierd but that is what happened, don't know if it was defective, or broke from vibration, heta or whatever.
