I couldn’t find anything on the subject but I don’t even know if I was searching for the right verbiage.

I was curious if anyone has tried mounting the 6.5” subs with an adapter into the third row stock locations…

I don’t really need a lot of bass and I’ve seen the barn door installs, the spare tire installs but mostly want to keep a pretty clean and stock looking appearance. I figured I would try to seal and reduce the airspace inside the cavity using foam insulation to build a shape and then either fiberglass the inside to make things a little more solid but I’m definitely open to suggestions on this part since I’ve never even seen what it looks like in the cavity.

 

Because the original speakers, (all) are oval and mounted on an oval housing, you'd have to fabricate something for the round, or square sub speaker so it can be the clean install behind the trim panels that you want.

 

today, while sitting in my car, a small sedan passed by me on the driver side.

the boom box was so loud, that my blue jean pant legs started vibrating.

talk about Hearing Loss,
those folks don't have a clue what they are doing to their ears.....

30 years from now, they will wish they hadn't been so stupid.

I was born deaf, and manage some hearing thru the Grace of God and a fantastic doctor, who "reconstructed my inner ear bones and junk"

full time choo choo noises go thru my head all the time. the doc calls that Tinnitus.... I call it noise.

only one ear works, so the TV has to be OFF, or I cannot understand a word you say to me....

it takes 2 ears to cancel out extraneous noises....
with only one ear, the noise just adds to the noise.... and I can't understand a word you say.

 

Thanks for the pic 01_Excursion, I planned on making a plate adapter and sealing it to allow for the 6.5” Memphis sub. On the inside of the factory enclosure does it have a lot of cracks or passageways for air to escape? I may just have to rip a panel off tomorrow to start planning this out.

Just so everyone is clear, I’m not trying to bust out windows or even annoy the car next to me. I do like good sounding music and the component set that just got installed did wonders so far but I need something to fill in those lower frequencies.

 

I don't have any other pics of the factory speaker enclosures. I never studied them I don't know if the back side is sealed or has a foam gasket. My 6 speakers were replaced by the previous owner, and offer satisfactory quality for me. I also have 2 of the last ever made round Kicker Solo Baric speakers in an enclosure behind the 3rd row seat for my bass, and 2 amps driving everything under the drivers middle seat. You don't have to justify how you want your music in your vehicle, you do you. You made it clear in your initial post that you were not looking for lots of bass. The post above your last one clearly doesn't offer any supporting information that you were asking for. I'll post another pic of the same rear quarter speaker at a slightly different angle and range showing the enclosure a bit better.
Another option would be to add a small bass box under the middle row seats too. Something like those will give you what you need without any modifications or extra construction to the interior.

Thank you again01_Excursion for the additional pic and I have looked at the powered enclosures and have gone back and forth with them. I think if the two 6.5” Memphis subs won’t fill the void in my music then I will probably go with something like what you suggested. And you are definitely right about the other post, nothing of value. I know that loud noises greatly induce hearing loss, listened to jet engine for way too many years. I will report back in when I make a little headway on this project but right now I have to finish the dining room table I’m working on for the wife!

 

So I finally finished the install of all components to the stereo. 1st and 2nd rows have Memphis PRX570C and the tweeters are mounted in the B and C pillars. I have the Memphis PRX624 mounted in the 3rd row. Everything is wired to a Memphis 600.6 ATV amp mounted nicely below my second row seats.

At first I just ordered adapters but once I got the interior panels off I realized that there isn’t really any kind of enclosure there and the when the speakers reach their max excursion they were really close to hitting the interior panels so I removed the 3 bolts holding the speaker mount on and used a 1/2” piece of plywood to make a flat panel to mount the subs. Once I had the adapter made I noticed I had to trim away a little sheet metal so the massive magnet would fit in the panel. I had plans to stuff that massive cavity with some rockwool to take up some of the dead space but the supply store in my rural town doesn’t carry it anymore so I buttoned everything back together and I can say that it is very clean sounding. The bass isn’t so loud that every car around me is going to be listening to my music but inside the truck it sounds like you get the full spectrum of music which I love.

I wish I had taken some pictures along the way but when I get the chance to work on something I get to it because I don’t typically have that much time to get things done.

I may still do a 10” in a sealed enclosure in the barn doors for the punch but for now I can at least hear all of my music. Hopefully this helps someone else out if they are wanting to do a full system in their truck.

future plans are a 2010 dash swap with a Memphis marine head unit for a small footprint but still have a way to control the audio and I plan to integrate an iPad into the dash for navigation and streaming shows for the family on road trips.

 

I'll be sure to turn my stereo up when I'm around John

I've been around loud music and heavy machinery for nearly 40 yrs....My hearing is still extremely good. I've only lost high frequency hearing but that is typical human nature as aging continues.
