The sail panel speakers foam went away. These a re 4ohm/4ohm dual coil spacial speaker. Could not find a replacement in my price. Found these re-foam kits. check out these pics. Only about $20 a speaker.
OK, forgot to comment the pics. First of all, Tootsi Rolls are a mandatory part of speaker repair. LOL.
Instructions say if the foam is not an exact fit, then cut and glue. And I did. As per the pictures, I cut the foam at an diagonal just because... The foam was just a little too big and had to be cut. It worked well .
The kit comes with plastic spacers for the voice coil. That keeps the coil from rubbing the magnet, etc. The spacers were too wide for the small diameter of the OEM coil/magnet. I had to cut the spacers to about 1/4 of their size to work and space the coil properly. The one pic shows the original spacer (rather wide) and my cut/trim spacers sticking in the voice coil. Yeah, you have to take a razor and cut off the paper cone. Then glue on the new one they send.
Put the meter on the speaker. Reading was 4. OHM on one coil, and 3.99 on the other. So I'm guessing these speakers are OK. On the back side of the speaker is printed is "4 ohm/4 ohm". for each coil.
This is an inexpensive to refab the OEM speakers.
Speakers are installed and sound just like the OEM speakers they are for a low price. Checked the OHM on all 4 coils and they were between 4.1 and 3.99, so no shorting. One problem was that removing the speakers, the U clips that the screws go into in the top two locations fell inside the body on both sides when the screws were removed.. Uggg. Found same U clips at the local auto parts store on a rack. They pushed on very tight to the sheet metal holding tight while the speakers were installed.
So, a low buck fix that keeps the car OEM and sounding original. That is all I wanted.
Got both speakers done and installed. Every thing went well as per the photos above. A problem is the U clips falling loose into the body. Found new ones at the local popular auto parts store in a blister pack rack.
Anyway none of my prior firebirds or camaros had the monsoon system. So it was a surprise what these speakers make. I did check door panel and rear hatch speakers and those were fine. They did not have the same foam roll on them.
On the new work, I let the glue set for a few days.Then installed. When I cranked up the local FM station the speakers did not fuzz or warble or do anything they are not supposed to do. I was wondering how the overlap on the foam roll ( see pics above ) would affect sound. No issues here.
So this is an easy fix to the OEM Monsoon system. Back to oem. By comparison, my 2019 Hyundai OEM stereo kicks the Monsoon to the curb. LOL But now I have the OEM Monsoon system back, with ZERO mods to wire, amps, etc. It's just back to stock. A low buck fix.
Ummmm.... Been a few days with the repaired speakers. Sound like OEM. The new roll made no difference in sound, even the cut/overlap of the roll in the pic. Made no difference is sound. Actually not foam, looks like solid rubber roll.
So......... This is an easy and inexpensive fix to failed speakers. It saves all that trouble of looking for dual voice coil replacements which don't exist except at very high prices. If you are on a budget this is a low buck way to fix the Monsoon stereo. It cranks hard, and the repaired speakers are holding together. I say go for it.
It has been a week of cranking the stereo. Ummm, Still sounds like OEM Monsoon . Huge base. Did not realize the 6 inch speakers I refoamed were bass. Wow. Kick ***. But still not totally clear. Might just be the radio stations here. They are hard to pull in. Still looking for a CD to put in and see how it really sounds!!! LOL
This was a low buck fix for foam deterioration.
Playing loud the speakers still work. Glue and new rubber are holding up ok. I mean they are really holding up tight. Took off the grills Thump, thump, thump and glue and roll edge are tight.
At 66 I have the equalizer pushed up at the last to slides so I can hear it . Ugggg. Getting older sucks.
Anyway, A set of foam rings fixes things and you don't have to find a dual coil for 400. Just fix what you have for 20.
As of today, the speaker repair is holding up fine. The glue that in included with kit is the strongest rubber cement I have ever dealt with. Sounds just like OEM. Happy to have some music back and the OEM is just fine for me.
BTW, both top nut/clips on the speaker screws fell into the body when removing the speakers. Found the perfect match in a blister pack on a rack in the local auto parts store. Spent a lot of time going to Home Depot, Lowes, Ace Hardware, etc looking for those clips. No luck finding them small enough. Autoparts store have them.

Out. LOL. I mean its good.
The factory head unit is a notorious distortion producer at higher volumes so you will never get clear sound out of it regardless of what speakers are connected. The sail panel speakers are mid-bass filtered by the Monsoon amp although the factory calls them "subs". You can find out lots more about your Monsoon system in the Monsoon FAQ sticky linked at the top of this forum.
BTW, running all of the equalizer slides at the top does nothing more than increase overall volume. The slides are like individual volume controls for specific frequencies so you can emphasize bass, midrange, treble based on your preferences. But putting all of them at the top just gives you a flat signal profile only louder... just as though you had left them centered and turned up the volume.
