check your settings on your stereo and the amp make sure you have changed to 1 ohm on the amlifier for a briged connection to a subwoofer and change from lpf to hpf on the amp there should be a switch.

Storing as in Distortion? If that's the case lower the output gain from your amp until it is suitable to you ears. It might be all the way open, besides this should be adjusted system to system.

If the amp uses TIP35Cs and TIP36Cs, those will be the output transistors. Measure the resistance between legs 2 and 3 for each of the output transistors. Do any read near 0 ohms?

If your car battery was not disconnected when the amp was installed them your amp has blown, it could just be a fuse or at worst the circuits inside have fried. Check your fuses if not take it to a certified car audio shop and ask them to have a look at it for you. Need more information to help you bruv, but from what you have said it has been connected with the car battery still connected

Hello michaelandta,

Check your filter settings on the front channels. It sounds like they may be set to "high pass" which would eliminate the bass frequencies. If you are using the amp to power normal speakers, it's usually best to set the filters for "full range". If the amp only has "low pass" and "high pass" settings, turn them both OFF.

Hope this helps.

the left and right clips are for your subs to tell your amp that they are not going to (flatline) clip which is when you start to lose clarity and get distortion

Check your ground and make sure it is properly grounded needs to be a very clean paint/gum free area tightly bolted.  Next Check and make sure you are recieving your 12 volts (not running)  13 (running)    by placing your test leads from positive to ground...... then make sure your power remote from your head unit is putting out voltage.
