Question about Jensen LXA300 Car Audio Amplifier

1 Answer

Jensen LXA300 Amp. need to known specifications of electron. part

I am repairing a Jensen LXA300 300watt 2-channel bridgable amp. and need to known the details on a "transisitor"(I think). The device is located inside the amplifier on the outer sides of the amp. This device looks like a chip, but has a metal piece that goes over it(there is a duplicate device right next to it that is also covered by this "metal" piece). I need to known the specifications of it so i can get a replacement part. Also, this device is the small "transisitor", NOT the BIG one. P.S when everything is put together this device is fastened down to the metal side fins.

If you remove the clamp, there will be a part number on it. Post the numbers on the transistor and we'll go from there.

It says 75 watts rms per channel. what would the power,when u 2ohm load each channel?


If your amp is 2 ohm stable it will do 75 rms to both sides maybe a little more.

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.

Subwoofers


This will depend on the amplifiers capabilities.

I will give 2 different scenarios.

#1 Stereo configuration

If the amplifier supports an RMS power output close to the RMS input power of the subwoofers then run the amplifier in stereo mode. For example 150 watts RMS X 4 channels driven at 20-20khz. (If you can provide a model # for the subs and the amp your looking at I can help you further with this decision.

Wiring for this is easy and simply involves matching the connectors for 2 of the channels (Front or Rear) to each of the subwoofers.

#2 Mono Bridged mode.

If the amplifier is lower power but mono bridgable you can bridge two Pairs of channels and power each of the subwoofers this way.

Generally speaking a 2 channel bridgable amplifier will be able to at least combine the wattage of each channel into a single monural channel and in many cases its actually higher.

So you would bridge the front 2 channels into a single bridged mode for one subwoofer. and then you could bridge the read 2 channels into another bridged mono channel for your other sub woofer.

For example if you had bridgable amplifier thats 50 watts RMS X 4 you coudl very likely (Generalization based on quality of amplifier) send 150 watts RMS to each subwoofer.

Again I would need to know what amp you're refering to to provide specific wiring instructions. Many Bridging amplifiers either have a single switch that will send them to bridged mode or you would use the positive + terminal from one channel and the negative - terminal from the other channel or a combination of both.

What if you wire a dual 2 ohms in series producing a 4 ohm load and bridged it? then each channel would now see a 2 ohm load, right? does a total of 4 ohm load in bridged mode also burn my amp?


i have this amp i bridged it to 2 ohms and its been about 3 months its stable havent blown any fuses and its a big difference in sound to. 2 ohms with this amp is definately the way to go. i used to pioneer 12's.

Jensen xa2150 amplifier


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
