Re: power on

You must use same cable used to power sound unit.

also check if the sound may have a remote connector.

What fuse do i use for my Jensen 2 Channel Bridgeable Amplifier with 300 Watts Peak? thank you.

Watts = Voltage x Current

300 = 12 x Current

Current = 25 amps

Sounds like a 30 amp slo-blo fuse would be about right -- you could start with a 25 amp and see if that holds it.

I need a wiring diagram for the jensen lxa400. Pushing 2 kenwood 6x9 (200 watt rms each) and 2 dual voice coil 12's (300 watt rms each) in a truck box. Everything is 4 ohm. Thanks, Curtis

you shouldn't need a diagram all you need is these items here.

purchase a 4gauge wiring kit

run a a power line from battery to amp with a in line fuse 6in from battery.

run a ground from car frame to amp. ( scratch paint and screw it down with an eyelet for good contact)

run a remote from radio to amp.(blue wire)

run rca's from the radio to the amp ( sub input on back of radio)

finally connect your speakers.

You need to wire the ground wire first, because this will make sure that the amplifier doesn't blow when you connect power. Your power cable comes last. First do the ground, then remote and follow with the power. Make sure the ground is attached to the body of the car properly, otherwise you will get poor sound

Check and see if its dirty inside, dust and smoke are known to cause problems via shorting or not making contact... sometimes your fuses are a bit over the wall so it would be best to replace them... and check if you have a fuse between your battery and the power cable to avoid over powering the amp

You would have to contct Jensen for the parts. As far as I know, they will not release schematics. If you were going to repair it and needed generic information about the repair, let me know and I'll try help. The following page will help guide you through simple repairs.
