That is because your impedance is not correct. You probly have 4 ohm woofers wired in parallel. Try putting them in series. That will put your impedance to 8 ohms the amp will not clip, or go in protection that is what the red light means. Good luck
Check the impedance of the speaker set up. Reasons for going in to protection mode is that amp can't handle the impedance... Just incase you don't know what impedance means, it is another way of saying ohms!
red and green light? there is most likely a protection and a power light. The red I assume would either be a protection light or a clipping light signal. Does the amp kick off then these lights kick on red then to green?

try running the system with a cross-over configuration.
So your left + will be left + and your right + will be in the right + but put the right (-) where the left (-) is and left (-) where the right (-) is. If that doesnt work, then that means that you shorted out your audio out channels. the only way you can fix that is if you have good soldering skills. But other than that I'de say scrap it, unless you have the high outputs and then buy another amp, some mids and highs and connect the mids and highs to the xplod
I often troubleshoot these issues via a stereo head set, modify the leads so you can "Touch" them onto the Speakers Output Terminals, connect the "Shields" together, thats "Earth" and the other Two, are Left & Right... with the Amp's volume turned to about 25% volume, connect up the Earth wires to the Chassis with a clip, under a srew etc, just make good contact... then touch the Left & right wires onto the output, ya should hear sound... if not most probably the Output device(s) may have gone faulty.
Check the unit for any Fuses, Fusable Links etc, if they are OK proceede on to testing, I often troubleshoot these issues via a stereo head set, modify the leads so you can "Touch" them onto the Speakers Output Terminals, connect the "Shields" together, thats "Earth" and the other Two, are Left & Right... with a Sinal feed in & the Amp's volume turned to about 25% volume, connect up the Earth wires to the Chassis with a clip, under a srew etc, just make good contact... then touch the Left & right wires onto the output, ya should hear sound... if not most probably the Output device(s) may have gone faulty.
I have this same amplifier. I have noticed several ways it will "not work" during my ownership of it. I have it connected to a seperate battery to save my alternator, battery, etc as it is a power hungry beast for how low the output wattage is. Test the input voltage to see if you have enough, one way to see this is to check the "jensen" emblem that lights up. If you dont have enough power it will appear dim and only the right side lights up. Also the amplifier will not work if your speakers are "blown" even a little bit. Ive taken speakers that wont work on my lxa400 and connected them to a higher power amp and they will work (although they will sound horrible)
If youre smart you will keep the gain under 3/4 on this amp, I see some people have found out the hard way that full gain fries the amplifier circuitry. Not an expert on electronics but it smells somewhat like melting glue or plastic.
Ive noticed a lot of people have problems with the RCA jacks as well. There are 8 jacks, in two clusters. The first one is A+B and the second is C+D.
Note: You do not NEED Y connectors on this amp!
Connect your output rcas from the deck to top left and bottom left jacks of the left cluster. This will give you left and right (a+b) output from the first set of speaker outs. Then connect an rca patch cord from the top right and bottom right jacks of the first cluster and connect the other end to the top left and bottom left of the second cluster. This will give you output from the second set of speaker outs. Remember that this is in 4 channel mode. I dont remember the set ups for 3 channel but two channel I believe is the left deck rca goes to top left of the first cluster and the right deck rca goes to the top left of the second cluster. Then you just wire the speaker outs according to the picture on the amplifier. something like this:
|(+) - (-) +|
Speaker + goes to (+) and speaker - goes to (-)
Also addressing another issue if you want to increase the wattage to your speakers you just use a lower resistance speaker (2ohm instead of 4) I would not recommend using anything over 4 ohms.
As for the high level inputs, I dont recommend using them unless you have the plugs that go with them, its a lot easier to wire your deck rears to a line converter (changes straight speaker wire to RCA jacks) or to just buy a new deck with RCA outs.
Last item, common knowledge: 400 watts does NOT mean 400 watts!!! This amplifier puts out very little actual wattage (50 or 83 per channel depending on the load)
Hope all this helps someone out there.. Anyone who knows the 3 channel setups I would appreciate it.
