its ok it will work as long as u didnt hold it on there probably kill your battery tho but your amp is ok ive done it bout 5 times no and mine still works the same just had to replace the fuses in my amp
Check your speakers and Cables. I had some speakers that traveled in my small trailer and the vibrations of the trailer caused the diaphram to back off my horns. Once I got the speakers fixed the DDT light on my power amp stopped staying on so much.
Normally right positive and left neg. Your amp should have indicators on the terminals. Of the four you should have a separate + and - for each channel. This tells you which channel is for pos, and which is for neg. If no markings switch for each one left pos/right neg or right pos/left neg. It will only work on one way.
Hiya, dont have a diag either what you will have to try and is compare the left channel with the right. There will be 2 driver transistors (also likely on heatsink) close to the outputs. Check which driver drives which output on the left, then match it on the right. Those same drivers could very well also be a problem on the right as they often go with the outputs. There is a possibilty they have smoked again. See here to test FETS http://www.4qdtec.com/mostest.html
Basically the left will match the right but not similar locations but definitely by track joins.
Also check the power resistors at the output. Often also go.
The amp should produce no output when using the left negative and the right positive.
If the amp works bridged (left positive and right negative) with one speaker AND works when you connect one speaker from the left positive to the right positive, it would appear as though the right channel isn't getting any signal.
Try inserting only the left signal cable (nothing plugged into the right RCA jack) to see if the right channel will work when a speaker is connected to the right channel speaker terminals.
I recommend you swap your left and right input cables to make sure it's not a source issue.
So from your headunit, plug the left channel output into your amps right input and your right channel output into your amps left input.
If the same side is still not working then disconnect both (or single speaker if it bridged) the speakers from the not working side at the amp. Connect the front and then the rear speakers individually and retest to see if one of them works.
If one does work then check the cabling and speaker connections on the one that doesn't. If it's shorting out anywhere it will stop your amp from powering that channel.
Failing that, it could just be that your amp has partly failed.
