Question about Jensen XA2250 Car Audio Amplifier

1 Answer

No sound from speakers.

I bought a Jensen XA2250 and hooked it up according to the manual. It played for about 20 minutes with no problems. Now there is no sound at all from either speaker. The power light is on and not in protection mode. The speaker wires were replaced but no help. What's wrong?

Re: No sound from speakers.

Try with different speakers but disconnect all power (20min) cables first.

Once playing, after about fifteen minutes of playing. it over heats and cuts off until it cools down.

Your problem could have more than one solution. The first problem could be the way your speakers are hooked up. Speakers hooked up in parallel lowers the resistance and some amplifiers overheat with a speaker load of 2 ohms or less. Another problem you could have is not enough ventilation for your amplifier to remain cool. Fifteen minutes of play time suggests your amp is getting hot really quickly. You might even need to install a cooling fan where your amplifier is located. Hope this helps.

Amp works when beaten

It sounds like you have a broken connection in the amplifier. The first thing to check is the fuse. Sometimes the contacts become weak on the fuse holder and the connection becomes intermittent. Any other troubleshooting would require opening up the amp. Any repairs would require resoldering the broken connection.

Let me know if you have any other questions.

Jensen LXA400

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.

My amp keeps going into protective mode.

try to lower the SLA option on ur deck maybe the amp is pulling to much current from the battery try putting a battery with more AMPS
