i have a 5ch amp powering a 10" sub. It was fine and sound good enough for me before. Problem started happening after I disconnected the battery and reconnected back. It seems the base is lost or I should say it's not as "boom" as before. It sounds so like a stock sub now. I checked the stock HU audio setting and adjust everything back to where it was. Still the base is not hitting as before. I checked the fuse on the power line and it's fine.

What else can I check? how to solve this problem?

Please help me out here guys.

Thanks

 

You may have blown an individual fuse on the amp itself. Look in the manual that came with your MTX and see what kinds of fuses it has (internal or external)
