How do i bridge all 4 channels on the jensen 400 watt 4 channel lxa amp ?

  • This amp is not "bridgeable" at all. You will either blow the front end or blow the low end voice coil in your sub.

Have Power going to the amp. Amp does not turn on. Do i need a remote? Bought vehicle with amp in it. LXA 600 Power light does not turn on.

you need to make sure you have 5 things.

1. power connection to the battery/amp
2. make sure you have a remote line radio/amp
3. make sure you have rca's radio/amp
4. make sure you have a ground amp/car frame ( scratch paint away for good contact)
5. make sure the speakers are connected to the radio.

if all is ok then check the inline fuse from the hot wire from the battery is not blown and the fuse on the amp is not blown.if so replace them. with the proper amp fuse.

The led on my lxa 600 watt amp in my dodge magnum

If the light is all that is on then it will be fine. It would take days to weeks for it to kill todays car batteries. If the amp is drawing more power than just that though, I would move the remote wire to the ignition or the headunit, because the fusebox is getting constant power to tell the amp to stay on.

well i will let you know now that 400 watts running into two subs like that will never match. You will want to run only one sub or get a bigger amp. But for that amp a standard 6 gauge power wire will be sufficient to run it. The ground wire about 4 gauge is good.

No sound comming from amp

If it only worked for about a month, then you probably did not get your speaker load right. Check that out before you repair the amp and put it back in. Good luck.
