Sub Woofer Installation, Tried to get better Audio without carving up the car Options

[bbrock]

@horrizontally-opposed Pete, I have picked a JL Audio sub to try in that area. My plan is to take lay some foil wrap into the area, and then work my way out with fiberglass, build a sealed enclosure, and it will be protected with one of the perforated Aluminum plate foot boards. I will be painting or anodizing it black, and adding traction tape over it, leaving the holes exposed. Most likely add a sound Matt of the back side to reduce the opportunity for the AL plate to vibrate. That would annoy the (IMG:style_emoticons/default/stromberg.gif) out of me.

The JL sub I picked at @BBRock suggestion requires ~0.35 cu.ft. for a sealed box. Ported would be a bit larger. I will most likely do a sealed, as ports tend to enhance certain frequencies, and since I don't just play one key of music, I do not need to tune the system.

Tuned ports would be handy for Gregorian chant.

(IMG:style_emoticons/default/popcorn[1].gif) Looking forward to learning how this turns out. My Infinity Kappas arrived this week so I'll be making adapter plates to fit the stock grills. I'm almost for sure going to use that same sub. I downloaded the manual and saw they have detailed specs for sealed and ported boxes (including tubes). Planned to do some measuring maybe this weekend. I was afraid the bass from a ported box might be a bit too much. I'm not looking to pimp my ride. But now that you mention Gregorian chant, I'm thinking how ported would sound with my Australian Aborigine didge music... (IMG:style_emoticons/default/idea.gif)

@messix - I think that's the way to go but I can't find it on 914Rubber's site. @Mikey914 ?

We are actually retooling on these right now. I'd be happy to post up a GB but these are 4-5 weeks from being ready. I could do the
Shell only at $66 if I could get 10 takers. I may even be able to get it lower but depends on how many are interested.

I'll post up a GB shortly.

@Mikey914 was this GB ever posted? I'd be interested in a shell.

[Mikey914]

We are in the process of changing up some tooling, so I had not, but yes we will.

Give me a few days and I can get posted up.

@mikey914 count me in!

[Chris914n6]

8" ?
what's the internal volume?

Looks about right for a small box sealed 8" I have, and I hate working with fiberglass (IMG:style_emoticons/default/beerchug.gif)

^ This setup, but with an 8-inch (or smaller) sub without the periscope and the same size as the foam pad would be a fabulous add to the 914. If you do this Mark, count me in...

Actually that has been on the market, but the box is thicker by 1-2" because the 8" sub is deeper than the foam block. Plus the air space needed so the speaker actually works right.

I like the 'periscope' design as a good compromise as it keeps the foot space as is.

A 6.5" in a ported box might be a good compromise for the given space.

Another idea...shallow-mount Pioneer sub designed to operate in free air, for $72, at 7 inches in diameter by 2.63 inches deep.

Curious to hear others' thoughts on this...or whether 914rubber's setup might even enhance this? The idea of a sub in place of the footrest foam—without losing any legroom—remains highly appealing.

Also interesting, at $92…

the 12" version of the infinity gets really good reviews, for performance, very interesting design.

[Mikey914]

Yes we will be providing just the vented unit, you can install your choice of sub. It will be interesting to see how they all compare.

Maybe it's a bit against the purpose of this thread but years ago in my smart-car I used the predecessor of what is now the Pioneer TS-WX210A.

It's an active subwoofer which sounds more than adequate, especially in such a small space. And it's easy to hide I guess.

Here’s my sub. Fiberglass box replaces foam block in passenger footwell. 8” sub with an amp and I get pretty good sound.

It appears Pioneer has a similar sub currently, TS-WX130DA.

Nice install, Rob!

Any detriment to passenger legroom? I had a similar setup, but I could have and should have done better on legroom...

Any news on this? (IMG:style_emoticons/default/popcorn[1].gif) Baby needs her bass... (IMG:style_emoticons/default/biggrin.gif)

Me, too. I just got back from running an errand with my 914. Beautiful day, open road, top off, car driving beautifully, and Rainbow's "Since You Been Gone" blaring on my play list. At least I think it was. The sound was so tinny I couldn't be sure (IMG:style_emoticons/default/blink.gif) (IMG:style_emoticons/default/hissyfit.gif)

Thought I would report that the JL Audio sub mentioned earlier in this thread does NOT fit as a stealth installation. The magnet is just about 1/4" too large in diameter to fit into the footwell foam space. If you are willing to give up about an inch of footwell space, it would work, but I'm not. I'm sending mine back and will get one of these instead:

The JL sounded really nice though. Even just using a cardboard box for an enclosure, it paired very nicely with my Infinity speakers.

@Mikey914 Any progress on those enclosures? Will there be a sealed enclosure option? I'm guessing the port could be sealed up easy enough, but curious.

Here’s my sub. Fiberglass box replaces foam block in passenger footwell. 8” sub with an amp and I get pretty good sound.

Nice install, Rob!

Well, they have to keep their feet off the speaker grill but it is just the foam block replaced with a fiberglass sub enclosure.

I don't know why one would have to go to such a large driver to get decent bass response. I did a budget stereo install on my '91 Targa for $600 that included a Kenwood powered sub, an Alpine front end and small amp with Rockford-Fosgate speakers. I know Infinity and JL are far superior components, but I've got two in college. The powered sub is good enough for me. It's not competition level bass, but I don't need that anymore (I save the hearing damage for jams).

The point is that I don't think you've got to go with a large sub to get decent bass.

As a side note; what happened to EQ's?
I loved being able to adjust the the EQ when I took the roof off my 914. I had an Alphasonik 7 band that fit the center console and worked great. Most front ends now have some EQ, but what can you do with a 3 band parametric??
