Problems With My Jensen 425 Watt Amp

My Amp was fading in and out it would shut off and then start to turn back on. When i took the panel off of it there was a copasitor that was loose. So i fired up my soldering iron up and fixed it when i hooked it back up in my car i was starting to put my fuseblock in and it started to shoot sparks from the inside wat would that be and how can i fix it

Have you checked your Ground wire connection? It may be grounding in and out. I have had a similar problem and it ended up being the ground wire, I have the same amp, use it on nearly full level/bass works great 0 problems

It's normal to see sparks when reinstalling the fuse. But they should only be produced inside the fuse holder when the fuse makes contact with the terminals of the fuse holder.

Did you reinstall the capacitor with the correct polarity? If you installed it backwards, it may have blown out or could be causing other problems.

Did you possibly bridge the connections in the amp when you soldered the camp in?

It's possible that something failed and caused the cap to melt out of the board. The failed component may have caused the fireworks inside the amp.

    I would guess that the power supply FETs have failed. That's generally the only part that sparks or smokes when an amp fails. Let me know if you have any other questions.

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.

I am looking to buy a 1200 watt jensen 2 channel amp. what model is this? is there a jensen 1200, i have not seem it.


I would recommend you purchase a brand name 600watt RMS amp instead of a Jensen 1200 watt peak amp. Trust me you will notice the difference. Try a kicker, hifonics, MTX, audiobahn Autotech... Its not the watts its the quality of the watts..

VR 200 Watt amp


Disconnect the wire from the remote turn-on terminal of the amp and insulate it so that is can not make contact with anything.

With the wire disconnected, does the amp remain on?

Power Problem, LED Lights up and then shuts off


Do you have the switch or activate wire on the new amp. to the right hookup? If you do, then theres a problem with the amp and if your not a tech these can be a difficult thing to trouble shoot. Take back the amp or seek out a pro to test it on a bench. Good Luck
