Has no power ,won't come on.

how do you know it is fully charged? i think it may be dead battery

un hook your battery for 15 minutes then retry to start

Your power suply is defective and needs repair.
Or the power amp is shorted will blow inside fuse power line
distribution.

Check the input power is coming or not. Check fuse inside control board & wiring too. If everything ok then it's problem of control board

If the red light won't come on it is not getting power.First,try plugging it in to a different outlet,or unplug one of the gadgets you know is working and plug the tv in there.You are simply switching.If you know that there is power coming from the outlet and it still won't come on then you'll have to check the cord;don't go much farther than that without expert help.

Make sure the remote wire is hooked up. You can run a small wire from the power terminal to the remote terminal. If it powers up, then you have a remote wire problem. You can run a remote wire from the blue power antennae wire of the deck.

Basically you cannot break you woofer with too powerful amp, but you can break it using too weak amp. This is because if you don't have enough watts going to you woofer the cones movement isn't controlled properly. I'm usually using +20% to the woofers RMS and peak power. This will also make the amp last longer because you won't use it at it's peak performance all the time. If possible use manufacturer whose prising policy matches your woofers manufacturers, that way you won't end up with "2000w peak power" cheap amp with real output of 30w. and in the other end cheap woofer won't handle expensive amp with real 600w rms so well, you need to find a midlle way here. Hard to say without knowing the make and model of the woofer.
This is a taste question for some people, and I haven't build a system to match so powerful woofer ever in my life. But I'm pretty sure you won't go wrong with this one.

Check in the high amp fuse box under the hood as one of those fuses may be blown causing no power to several accessories.
