Thoughts - JL Audio MicroSub in rear speaker spots
 

I have been thinking about how hard/easy it would be to incorporate one of JL Audio's MicroSub's into the rear speaker areas and having the sub speaker meet up to the existing speaker grill in the car panel.

If it would fit and I could fab a way of attaching it to existing points, it could be great for getting bass and keeping ALL the trunk space.


Thoughts on viability or is it more headache than it's worth and should just give up some trunk space?

P.S. I'm at the planning phase and will be replacing the head unit, stand alone multichannel amp, component speaker system upfront. Just wondering if I should be deleting the back channels for microsubs, or go bigger sub in trunk and keep back two channels...

You can fit some 8" back there.. The enclosure will be a challenge for certain

This car really makes me wish I had fiberglassing skills.

After looking at the giant cavity around the rear speakers when I did my car stereo, I wondered why a vendor didn't design a box to go there. There is a lot of room, it's just an oddly shaped space.

Delete the two rear speakers no matter what, they are pretty much useless.

If you want the most output, you'll likely get it from a wheel well mounted box in the trunk, not inside the cabin. This seems counter intuitive, but I've seen it happen over and over in all kinds of different cars.

That said, the rear side panel would like have a smoother response curve.

My biggest goal is to retain all the trunk space. I use it on a weekly basis and almost every inch, for stuff when washing the car, going to the store, etc.

This is why I would like to utilize the back seat area for bass.

It could be done with a fiberglass enclosure, and have pretty good response. Unlikely the microsub enclosure would fit behind the panel.

So find a custom faber and ask them for a quote.

Any idea on how much things like that cost?

Honestly, not cheap. If it's hidden behind the panel, it might not be as bad as it doesn't have to be finished. But for example, a pair of sealed mid enclosures for a door generally cost over $2000 a pair for a nice looking finished product.

:confused0068: 2-3 square feet of saved trunk space isn't worth that much to me.

Maybe I can look into getting the cavity 3D scanned and 3D printed. :D

There's actually a car audio guy that's been building small bandpass boxes using a 3d printer, but his printers not big enough for that area. I had him 3d print the fluid tonearm damper for my turntable.

I've got a couple of JL Audio 6" subs new in box that I bought years ago for a project and never used. I wish to hell I could fiberglass worth a damn because they would be perfect back there.
I currently have a 10" in a box that just takes up way too much space. Sounds great, but I really miss my trunk.

A couple/three owners pulled this off in this thread with subs up to 10" IIRC.

It was a lot of work.

That is my pic, and yeah, it was a lot of work. In the end it sounded fine, nice even, but then I made the mistake of putting my fiberglass enclosure for the spare tire well from my STI in there. Just SO much more when placed in the trunk. Some of it is the proximity to the driver and the frequencies involved - you just aren't far enough away and that location doesn't couple to the interior very well.

If you insist on doing it I will give you my enclosure for the price of shipping. It would be good if someone got something out of it.
