Also thought you would want to go as big a sub as possible to take advantage of IB?

IB is just like any other bass install, it's all about surface area and keeping all cones in phase with one another. One 10" gives you 80 square inches, two 8" gives you 100 square inches.

If you're going to enlarge for a 10", you'll need to go passenger side opening and make it offset of the existing hole. The deck is part of the rear cross brace structure, so the vertical plane is in the way if you stay centered. This will mean the edge of your sub will be firing almost directly at the bottom of the rear window seal. You can't use the driver side without having to extend cabling and relocating the trunk light/harness.

If you go with the 8" subs, you can keep them centered with the existing openings and don't need to expand them because the opening is sufficient to pass the volume of the surface area. No relocation of light needed either. May just need to reroute and secure the harness down the middle on the topside of the deck.

Enjoy!

Something else I was thinking about for both of you -- if you're going to use the rear side speakers, what are your plans to secure the speakers? If I recall, those speakers mount to the interior trim panel and aren't secured to the body structure behind them, essentially they are bottom mount. Adding a harder hitting or heavier speaker there could have unforeseen wear on the trim panels.

I honestly would just stick with 3-way active fronts, plus or minus the center channel depending on if you want driver only or both front seats imaged, and subs in the rear deck doing that IB sexiness.

Not sure if you were referring to me or him, I’m assuming him. But just to answer, I’m building a custom fiberglass enclosure for the subs and midrange drivers

Ok you sold me on the smaller woofer. The work for a 10" sounds like a PITA. Just now reading about the I6SW, now that could drop in the stock holes without any cutting.. although an enclosure would be required.

I'm not doing anything for rear side panel speakers, in fact I'm debating on gutting the stock ones. One of them has a bad rattle. Sorry to hijack the thread OP.

[JaxChris]

drfeelgood, I was asking you how you planned to address securing the rear sides.


WhyUMad1LE, the 6.5 sub may be too deep to top mount with the rake of the back window. Have a contingency plan to bottom mount and then consider whether you want to move to 7-8" woofers instead for most surface area without modifications.

OK got it. And I like the idea of considering bottom mounting the woofers.

For me, I'm subject to the constraints of the convertible*, hence me doing this the way I am doing it. I am interested to see how it sounds.

Will post pics of the box that we create for the rear fill midrange and woofers

No, we removed the center channel, Not enough available channels on my H8 to utilize it .

2.7" midrange will go in factory locations for now firing off glass, tweeters are in custom A pillars firing on axis.

Depending on how I like this setup I may of may not move to a setup with both the midrange and tweeter firing on axis in custom A pillars. I love that sound on my previous builds, and, IMO, it just looks better.

I have seen that a 3.5 midrange will fit in the dash. Have you found this to be true??

[JaxChris]

A 3.5" fits in the center channel location, but not in the dash corners.

Got ya!!

exactly... those corners are very tight, both diameter and depth are a challenge there

[Ulisses_KartunesAZ]

my last car had both tweeter and mid in the same dash location firing off the glass. (Toyota 86) speakers were focal flax. I'm now putting the same speakers in my Camaro but am wondering if I should fire off the glass or place tweeters in the pillars an mid on the dash. as far as time alignment what will create the most accurate sound? I'm using the same amp i ad before (VXI 600/6) all I've installed so far is a 600.1 and fix 82(for optical output) with a 10tw3 wedge box and am leaning toward the w6 stealth box.

[headgamez]

I am going mids in the dash, and possibly tweeter in the a pillars as well. I will also go with the w6 stealth.

Don't fight the crazy off-angle of that dash corner, fire off the glass and include center of cone to glass + glass to head in your TA measurement. If you want the tweeter in the a-pillar, consider airbag deployment in your cable length and make sure you don't mess up the microphone lead in there. The 3" driver from the Flax 165 set won't fit in the corner dash location, you'll need a smaller speaker for that spot if you want to go 3-way.

I'm sure I can get them to fit Sith some modding as I've installed them in a couple of sierras. opening doesn't look any different. and I just might fire the tweet off the glass. as for the center channel has anyone left this in play? at my last JL Audio tech meeting one of the reps had left his connected in his Lexus and said it helped with his TA. but what bugged me is that he kept contradicting himself with how we was explaining his sound system smh.
