Please tell me if there is any thing i can do to get more output.I already lost too much money in it.
thanks

What is the output on the amp, and the RMS handling on the subs (including the sub you blew)?

Also, just curious, where do you live?

First of all;

Is the amplifier installed correctly? Are the power, ground, and remote wires at least 12 guage?

Is the input sensitivity set correctly? This is also labled gain. This knob is meant to be adjusted to match voltage levels between the HU and the amp. Take it from me. I have been mistreating that knob for many years. This is not a master volume knob.

You should identify how many volts your HU is sending out, via your RCA pre-outs. Then identify what your amps input sensitivity range is. Then adjust the gain/input sensitivity knob to match the HU pre-out voltage.

This process can be more accurate if you use a DMM. It will be precise and will eliminate the guessing.

How are you bridging the amp? Is the amp bridgable? Make sure you are connecting to the correct terminals on the amp.

Last but not least. Are your fuses the correct size?

At least 12 guage. 1/8" or 3-4 mm.

If everything is correct like you say, then the amp is bad.

Something tells me that there might be a short. Make sure that the wires do not short out with any other sources.

You live in the Gulf? Which Gulf? What is the voltage, and amperage coming from your source?

Try running your amp in stereo mode. In other words do not run it bridged. See if it still burns stuff up. There might be a problem with that circuity. Sony is not a reliable quality product you know. Thats why they sell for $35 "buy it now" on Ebay.

SUGGESTION! Don't use that Sony amp, instead, buy something better. I don't know that I would want an amp flashing "222" on it. That's worse than Audiobahn's flames! I wonder if Sony makes a "666" model...?

There's Sony for ya, they can't pull the wool over American's eyes too much as far as price, but have it built in China and sold in an Arabic company? Yea, why not, and while they're at it, JACK UP THE PRICE! Sony is g@y sometimes...

find a good shop that ships internationally, and get yourself some quality equipment. Sony is not one of them

From your HU (cd player);

Run 12 guage wire for your remote switch that turns on the amp.

Next run at least 12 guage wire for the ground. Make sure it is fasnted tight and to bare metal that is directly connected to the chassis. Try and keep it under 18" (1/2 meter) if possible.

The power wire should also be at least 12 guage, and that gets connected to the battery direct. Install an inline fuse on the power wire as an added protection.

Run RCA cables from your HU to your amp. Make sure you route the RCA cables through another route so they are not near your power/remote, and ground wire. If you have them close, there may be interference.

Run at least 12 guage speaker wire from your amp to your speakers. Some people install an inline fuse on the positive wire of the speaker as an added protection. One fuse for each speaker.
