I have a 99 xj and have a mono amp and 10" sub I can't seem to get power to either. Why?

 

Need more info.... What brand model of amp? Is your remote wire sending power to turn the amp on? Are you getting 12v through your power wire? Do you have a crappy ground? Dont use seat bolts or any existing bolt for a ground find a nice spot of sheet metal. Sand out bare and make a ground with a self tapping screw or bolt. Oh and make sure your rca's are hooked up. I installed my four channel amp the other day and thought i screwed up when I had no output... Forgot the rca's.

Check fuses.... Its always fuses

 

I have a four channel but only one sub the remote seemed fine. Fuses are good where is the best spot to put my ground wire.

 

A short ground wire hooked to bare metal is always for the win

 

Find a good spot closest with solid metal if painted sand to metal self tap screw

 

Do you have a Mono or Four Channel ?

Check the remote wire with a DMM.

 

I ground under the back seat to the sheet metal with a jl audio ground lug. Also what is the final impedance of the sub? If the resistance is too low for the amp it may put it into protection mode.
