Help how to remove m490 amp
 

Ok i bought a 6 channel amp from a 996 cab so go to do a quick remove and replace get stuck training to remove the top right bolt. Socket doesnt go on due tonthe plastic cover, so thought maybe some one had a tip to remove the bolt, open end wrench seems a little tight.

Is the bolt turning but not coming out?

The top two amplifier bolts go into rubber nuts that expand, and they tend to disintegrate over time or when being removed. If the bolt is just spinning in place and not coming out, you will have to pull the entire bolt and nut out, which will rip the rest of the rubber nut apart. When you reinstall you will want to replace the nut, PN: 999 500 078 00. I used an adjustable cresent wrench when I replaced my amp, the bolts should not be difficult to unscrew.

The left nut came out and went back in no problem, its the right side i cant get the socket on. Guess i can give a cresent wrench a shot.

I should elaborate, the bolt on the right sude as you face the ampmbracket is like touching the plastic cover, so i cant get a socket over it. I will giv a cresent wrench a go.

Got out finally and installed 6 channel big difference. How ever i think i broke off the tabs on the power conector trying to remove the cable it finally came loose.

How to you access the plastic nut on the back? One seems little loose maybe spinning, but the amp is in tight.
