+ positive from battery ground is of course - anywhere on body put it on last.to avoid sparks if + is powered up! U can put a link between remote and positive it should then be on. Led normally goes blue rca s need a signal from stereo make sure its a amp out or sub out not an input on stereo set all knobs to middle and if speaker is connected to amp speaker + - it should be on, try an mp3 player with jack to rca for testing a known signal.amp may have loop rca make sure its on inputs.some have high inputs too using speakers wire stick with rca

check back connectors or mute button stuck

to use the high level leads, you have to isolate the wires going to each speaker (if using 4 channel mode) or isolate the wires going just to the rear if you are using 2 channel mode. you have to strip a small piece of the insulation off each speaker wire, and run it into the amps high level input harness. if you dont have the high level input harness, you can get a 2 channel high level to rca adapter for around $20. basically, you are tapping into the signal to the stock speakers to feed music to the amp. make sure you get all your positives and negatives correct. brighter wires are usually positive; however you may be faced with sa speaker which uses a grey wire, and another grey wire- the second with a black line. you will have to, again, turn to internet research to determine which is positive and negative, if the colors are not obvious.

Most common problem is cable connection. Wiggle each lead, positive, negative in turn at amp. while playing. I assume you have checked that you haven't inadvertently muted the system.

The player loading mechanism has failed, this is common, due to the low cost of these players they are not repaired just replaced except under warranty.

If the fuses in both the car and the unit are all good & the wiring is all correct & secure but you still get no power, your head unit is fried.

cant realy see the photo too well , but one thing these do have is a wire to the neutral safety switch that needs to be connected , its only on the indash models as its ******* in most states to have this on while driving , if it was just a player and had no monitor then you could put the monitor in the back , and all is well . ck your wiring diagram I bet youll see it

I've heard something about an extra screw being present and preventing it from playing and to take the screwnout.
