Check all of your electricial connections, especially the ground. I wouldn't suspect anything internal to the amp is the problem.

Ok have figured out that it is not the speaker,

You must be using speakers with lower impedance than what is recommended. This causes the amplifier to over load at high volumes.The protection circuit shuts down the Amplifier to prevent further damage.
And please remember no amplifier is designed to run at full volume, same as a car speed - Even though the speedometer might show max: speed 200Miles per hour would you do it???

Hi! I have a Jensen XA2150 Amplifier, from the speaker output I have connected a Subwoofer Sony 10 inch 1100W. Tha'ts gave me a nice bass sound, but now it's death! The amplifier have a 25A fuse,...

Have you checked the fuses inside the amp?Unscrew the cover and with the amp sitting on its back,remove the cover.You have 2-4 fuses,old round type,in there.

No sound coming from subs

You definitely NEED a source signal for the amplifier to amplify!

You should have a Main Power Wire, a Ground Wire, A Remote Turn on Wire, and RCA cables (or hi level speaker wires if your amplifier has them)
and the speaker wires to the subwoofers.

Ok . i have a pair of crossfire subwoofers, @

Your amplifier is 4 channel... and only 2 ohm stereo capable.

You will get the most power putting 1 subwoofer wired in parallel on each BRIDGED channel.

This will give you a 2 ohm stereo load.

Both + on 1 subwoofer to + terminal on amplifier bridged channel 1
Both - on 1 subwoofer to - terminal on amplifier bridged channel 1

Both + on 1 subwoofer to + terminal on amplifier bridged channel 2
Both - on 1 subwoofer to - terminal on amplifier bridged channel 2

Improper function

try hooking up your subwoofers in series. then connecting them bridged to the amplifier. as follows: positive from sub#1 into positive of amplifier left channel.. negative sub#1 into positive sub#2. negative sub#2 into negative amplifier right channel. turn the gain down as this will sound pretty loud.

check to see if the rca's have been disconnected from the amplifier or behind the head unit. if ok, thake a power meter and measure speaker outputs on the amplifier to see if voltage is present. can also check resistance on subwoofers to see if they are blown.

Amp is on, Subwoofer works, but no sound.

here is a short test you can try, remove the rca audio cable from the amp & connect a diskman or toher audio o/p device that you can hook up with the same rca wires, turn on the amp & see if you have sound. you can also remove the speaker wires from the sub & using multi meter read the ohm's of the sub, most subs are 4 ohm. Hope this help locate your problem
