Midbass from kickpanel speakers

I don’t have a write up. However here’s some pictures of what I did.

Those are some really nice adapter plates!

Thanks. I had a buddy print them for me. They worked out well.

I installed Kicker component 6.5s in kick panels and was very disappointed in bass. I pulled speaker and lined entire kick panel enclosure with killmat and also used killmat to create seal around speaker mount. Sounded great but could hear some pfffftt escaping around the trim clip holes of door jamb area. Added some more killmat around those holes and I was very pleased with bass. It takes some detailed time getting the killmat into all the nooks and crannies in enclosure but after all said and done the bass sounds great. Of course a seperate sub would of course sound better, but i decided against a dedicated sub.

Pics of the Sounds Good Stereo adapters I used. Really good quality

Late to the conversation but wanted to share my experience for what it's worth. Main issue has to do with airspace in the kick panel of the bronco as to why hard to get decent midbass. Car speakers are predominantly designed to work in larger door cavity. FYI, attached photo of passenger side where you can see the openings but can still be sealed up somewhat.

In my quest I started to look at speaker TS parameters, in particular lowest Fs and QTS. I am no expert so those in the chime in on the technical, but in small air space a low QTS and Fs driver is an indicator of a speaker that will play lower frequency in small air space.

I guessed on the airspace in the kickpanel at approximately .2 cubic feet then started looking at drivers and found the following at Madisound and with their help identified the following:

SB Acoustics SB17MFC-4 will play down to 85Hz in .2 cubic feet
Morel CAW634 3db down at 80Hz
Satori MW16P-4 or MW16TX-4
Scan-speak 18W/4531G00 3db down at 80Hz
Scan-speak 18WU/4741T00 3db down at 85Hz

Sealed up what I could, purchased the SB17MFC-4 for testing. Made some adapters tuned with dsp, band passed frequency to 80-400Hz and what do you know, magic.... midbass out of the bronco. Happy with the results and knowing I was heading in the right direction, moving on to upping the wattage (300 watts a side) to the kick panels so I stepped up to the Ciare HWG160-4 speakers. I am after SQ so I like headroom. If anyone is interested, I have the SB Acoustics SB17MFC speakers with custom adapters listed on ebay.

Happy to share more detail. In the Houston area show you or should I say play for you what I've put together if that would help.

what was the black rectangle of plastic used for?

Did you actually mount the amp underneath of the center console?

Do you have a link to the 3-D print file by chance?

The black plastic was used in place of the foam pieces that the factory puts in behind the big electrical connector. I glued them in trying to make it airtight. I also used spray foam to seal the area where the body clips pop in and where the foam is that allows wiring to pass thru up high under there.

The amp is located just in front of the center console more like where the cupholders are.

Unfortunately I do not have the link for the 3d model.

Are we talking Home Depot wall sealer foam or somethingSpecial?

thanks!

I used the home Depot special. Just use it sparingly!

I read a lot on polyfil and I'm not convinced it works. I also tried filling the sub enclosure in my FoST and heard no difference, so I didn't bother with the Bronco and I have no complaints with it!
The rag in the4 port will do virtually nothing...

How did all that sound deadening work? Plug the port?

Great I guess!
The sound is awesome and I have no buzz and the sub really hits nice...
Yes, I epoxied in a piece of plastic similar to the enclosure material...no foam fill! lol

I just did 16-17 sq ft sound deading inside out of the enclosure doubling it up on the exterior plus did the sheet metal and final 3-4 sq.ft on floor. Left port open. No rattles sound decent for cheap MB Quart sub.

I have been thinking of doing the same with raw drivers and a low QTS because of the small enclosures in the kick panels. I know most of these drivers are 3+ inches in depth. Where you able to easily fit them and use the factory grills?

Is anyone capturing before and after frequency response measurements when making changes to the kick enclosure? I've attempted to seal up the area, still have full drop off at 100hz. Near field frequency is good, can't tell if I'm fighting the enclosure or cabin acoustics (+soft top). AudioFrog GB60s with 200W RMS to each.
