Why would you give a guy a rating for being straight and honest with you. Your amp is fried and your respond as if it is his fault by giving him a non helpful rating. It is as if you are making him responsible for you frying your amp, I support his diagnosis and I have been designing and repairing them for over 20 years. I expect you to lash out and give me a bad rating also.

Sony X-Plode amplifier. NOT working


It is possible if the model amp you have is bridgable to 1 channel. Usually when you bridge an amp you will need to hook one wire to the positive side of one channel and the negative side to the other. You will need to consult you user manual for the amp or get the manual from the sony website for instructions on how to bridge the amp or if the amp is even bridgable.

Power acoustiks amp wont get off protection mode? how do i reset it? please help me i tried everything.


Hello nfox1987,

First you need to determine if the amp is defective or if something else is causing it to go into protection, most often a short in the sub or amp wiring.

Disconnect the sub(s) from the speaker output terminals and the RCA inputs from the head unit, and test if the amp powers up OK. If it does, the problem is in the sub(s) wiring or voice coils, or in the RCA inputs to the amp. Reconnect each one-at-a-time to determine exactly where the short is and repair or replace the defective wiring or unit. If it doesn't power up with the inputs and sub(s) disconnected, the amp itself is most likely defective.

Hope this helps.

Amp


The amplifier may be bad with a malfunctioning circuit inside. Also, it could be getting low voltage...make sure that the amp is getting 12 volts or more at the constant and remote leads. If it is connected to speakers, make sure that they are measuring more than 2 ohms (using a voltmeter). A good stereo shop can check this for you too.

You cannot parallel two subs AND run them on the Bridge. You must have at LEAST a 4 ohm load on the bridge, and 2 4 ohm subs in parallel equals TWO OHMS. BAD!!! Move each sub to it's own channel or your amp will soon fry.
