The foam may be a sound suppressor. Your vacuum may need a new hose. Old hoses have a liner on the inside that can collapse. Try removing the hose and see if you have good suction on the vacuum without the hose on. If you do it. Means the hose is bad or clogged

Sounds like the filter has never been changed and has disintegrated into the system

You mean 'bass'.

Amplifiers only amplify what is already there in the signal. By design, with all controls set to neutral or flat, they don't create or loose anything.

Speakers, on the other hand, are responsible for turning the electrical input into moving air. Good bass usually requires moving a lot of air.

Poor speaker placement or speakers wired out of phase with each other can **** the bass out of a room.

Web search for articles on bass response and speaker placement.

This receiver has a built-in Equalizer. Perhaps you could use IT to compensate for the tonal shortcomings of the speakers and environment.

This can be done one of two ways first there are two gold screws located in the trunk compartment one of them attaches the wire connection to the actual high bulb assembly this is located in a square hole. The second in in a small hole covered by foam tape these two screws will free up the assembly so you can pull the back of it up then push the front forward there should be a few clips that hold it down. This gives you access to the bulb. The second way is the hard way and more time consuming this is what i did before i figured out the first way. And that is taking your entire cabin apart. So just do it the first.
