hello ..try this ...www.eserviceinfo.com...takes a bit of working out how to get them .when you do .you have to download bitzipper (these are a rar file)...then adobe 8 ..bitzipper can convert to a pdf flie so you can read them...hope you have some luck

Make sure that your connection at the battery is still good-sometimes the wire corrodes up front when your system is installed for a long time-so check that out and of course the fuse that you installed a foot away from the battery so that you dont burn your vehicle down if a short occurs somewhere down the line

if the lights on and there is no sound it's either a cd player issue or your rca issue or the inputs for rca's on the amp are no good. or you have your subs wired at a wrong load to your amp and it is in a constant protection to avoid burning up.

sounds like maybe the wiring from the cone to the magnet is ripped or broken.... which is why when you push the cone in it works because it pushes it far enough to make the wires touch just barely, but when you let it go the wires seperate and you get no sound.

Your wire is built with slack, so when the cone goes in and out during a song, the wire can move with it and not get broken. but when you cone moves too in or too far out, then that wire can snap or become disconnected.

I have fixed this by soldering the copper wire, but you may lose some power because your copper wire might be a bit shorter(it will probly break again)... or you can lengthen it, but it is not easy to solder... some places will fix it for you but the cost may be more than what it is worth.

This is just a guess, take your speaker outta the box, and look to see if these wires are broken, lose, or frayed.

good luck.

first of all you should check the minimal impedance your amp handles , if is class d it should handle between 1-2 ohms total impedance in a mono conection , meaning whatever quantity of subs you have hooked to your amplifier,their total impedance should the minimum the amp handles that way all the power from your amplifier will be used.
