I need a wiring diagram or pinout for my jensen LXA300 amp, thanks

DON'T you'll kill the amp.
Cars use 4 ohms or sometimes 2 with dual voice coil subs.

On most amps, rmt (remote) is a wire that connects to your stereo remote wire to the remote port on the amp. The remote wire turns your amp on when turning ignition on and turns amp off when turning ignition off. This wire needs to be connected as without it, you will drain your battery.

Specifically it's 50x2 rms at 4 ohms stereo, 75x2 rms at 2 ohms stereo, and 150x1 at 4 ohms bridged.

the r+ and r- are for the right sub and the l+ and l- are for the left sub

Eith some wires touched, you dont have big enough fues or you have somehting hooked up wrong

well the "turn on" is just that - a relay inside the amplifier that allows the 12V Main to connect with the power supply on the inside of the amp.
hook up the remote turn on wire to a switched ignition source, and your amplifier will turn on.
If you are looking to TEST the amplifier - you can temporarily Jumper the remote terminal and the + terminal to get the amplifier ON - however when you instal it - you will want to put it on a switched power source so it goes on and off with the car.

If you need more help - im here.

This amplifier uses the left + and the right - for bridging. The manual is available from Jensen but you have to email them to get it.

go to the harman kardon site and download the owners manual and u can order any thing you need including a new wiring harness
