Kicker MX700.5 Teardown

[PaulPruett]

I have a customers MX700.5 Kicker amplifier in my shop. It will only play at very low volumes. I have enough technical experience to inspect the board, but I can't for the life of me figure out how to get it apart. I've removed the 12 screws on the end caps, but the won't budge. I can see a seam in the silver face, but I can't get it to budge either.
Any help would be greatly appreciated.

After removing the large screws and all screws in the RCA jacks, terminal blocks and fuse holders, the end caps pull off easily on the non-marine amps. The top cover is pressed into the red rubber strips but lifts off (sometimes there is one screw holding it).

Still no luck

I have all of the screws out. The cap on the power/ground side has some play, but seems to be stuck on the terminals even with the screws out. I think I'm at the point that if I pry any harder, I'm going to break something.

This amp is tricky to pull apart and the seal may be compromised.You will have to remove the sticky back label of the end panel to get to the screws underneath.You will not be able to reapply the label. PM me and I may be able to offer other suggestions.

It wouldn't let me send a private message. I'm not sure what you mean regarding screws underneath. Any help will be greatly appreciated.

The screenprint with a sticky back attached to the end panels with all the labels for RCA's,power and speaker terminals,model number etc, hides more screws. You will have to peel them off to access.

Is it possible to heat the decal to allow it to lift without damage?

For hidden screws, screwed into plastic or aluminum, you can use a small magnet to find them.

I think I see what you're saying. I'll give it a whirl when I get to the shop in the morning. Thank you all for your help! I was at a loss.

This is what the end caps look like without the decal..note the holes where the screws would be.

An externally hosted image should be here but it was not working when we last tested it.

Perry Babins suggestion is worth a try. I've never seen this done, we replace the decals before they are returned to customers.

If you can slide the amp out of one end, only remove the decal on the power supply end. That will leave the one on the other end perfectly intact. When you peel them off then reapply them, they don't go back on perfectly smooth because the adhesive doesn't lay flat.
