6X9's in doors...who'd be interested?
 
I'm starting a box project in my spare time and figured I'd ask to see if you guys would be interested in something similar. Basicly I'm just building a box that extends from the map pocket up far enough to be heigth friendly with a 6X9, and wraps onto the dash slightly so that the speaker is kinna aimed at the driver/passenger. Everyone I've talked to seems to think that a 6X9 up front is a little bit over-kill...but I like the way it sounds free-mounted.

What do you guys think?

ae1969 08-10-2004 02:50 PM

I run a 5 1/4 MB quarts component up front ..... and that fills the front just fine.

It would be interesting to see..... 6 x9 up front.... I would imagine it would be extremely bulky.

I am hoping you are planning on making a fiberglass box that will blend in somewhat? or are we talking an MDF box....

Makenzie71 08-10-2004 03:00 PM

yeah...I was thinking a big mdf cube that'd just stick out from the door. At first I thought it might look bad but then figured "nah, I'll just put some gray carpet around it."

~no~

It will be blended in with the interior somewhat...but the interior is based on straight lines so it'll still look kinna out of place at the angle I want it at.

And it will not be made of fiberglass. It'll be made with either a steel or hard-board frame and covered with (that fluffy blanket stuff, can't think of the name) then either cured with polyeurethane or polyester resin. I will then try to find a similar color vynil to match and wrap it...or just paint it. I believe fiberglass should be kept away from interior jobs.

only real problem I for-see is the removal of 3" of side-to-side leg room...

ae1969 08-10-2004 04:01 PM

LOLOL ... I had envisioned a carpeted box..........hehehehe

It may still be way too tight for a 6x9 up front....

Fleece is what you were referring to as fluffy stuff....

I use the fleece/resin for the shape but I always add fiberglass to reinforce it. The resin cracks way to easy....

Makenzie71 08-10-2004 04:05 PM

depending on what kind of framing I can use, I like to use polyeurethane. Polyester resin cures too quickly and the fabric soaks up a lot of it...a bad combination. This causes all kinds of streses and make the mix brittle and easy to crak. Polyeurethane, which isn't any good at all for sub boxes or anything, cures slowly and will flex with wear. Much better product for tight spaces and longevity.

Makenzie71 08-10-2004 05:30 PM

meh...I might take this on later...I settled for something a bit less unique. Pics later...unfinnished product, though...

you're still not going to able to hear the bass response appropriately, but it may be worth wasting money on those...
OR
you can remove the interior add a higher quality sound proofing material ( including behind the rear seats) and insulate the doors better and then add a better audio system to you car.. that'd work.
BUt most people do hear a difference even if it's not a higher
quality difference..
The low end of the exhaust tends to cause problems with the low end of your audio.. which is why your speakers are fried to begin with.. too little wattage being cranked way too high..

Makenzie71 08-10-2004 08:10 PM

The stock Blaupunkt speakers were fine, except for being 18 years old and the eurethane was rotted away...

Bass is not a concern...it's sound qulity and volume. I like to listen to my music loud. A 6X9 designed to handle 40w (nominal) is going to provide much more sound than a 4X6 or smaller speaker designed to handle around 20~30w when the tunes are turned up.

I want the actual sound to come from the speakers in front of and behind me. Bass response comes from the 8" thumpers (soon to be dual 10") in the hatch.

Adding all that insulation just for a better stereo sound is not appropriate to me...it only makes the car heavier.

Hey slow down I'm just getting round to my boot install before even heading upfront (the speakers up there aren't to bad but need a wee bit more bass)..................6x9 upfront in that position definitely sounds a bit OTT not sure it would look gtreat either. Some dynamat in the doors and better speakers improved the sound quality in mine no end, but intend to fit more expensive ones later. Anyway just wondered if I put a smallish sub in the back against the rear seats (mdf triangular box boot width)......I want to put the amp behind perspex (lit) will this need a cooling fan or will movement of air from the bass ports be enough?

Frank B 08-11-2004 08:05 AM

so will the bigger speakers..

Depends on how large an amp. If you're just pushing a couple hundred watts then not really.

Makenzie71 08-11-2004 03:49 PM

Not as elaborate as I planned on them being...but they do work well...

despite my intentions, ae1969, I kinna did it anyways...lol.

Holy crap..............

Mackenzie............ you do know you have to much time on your hands... LOL

I think an MDF cube would of been more 'Stealth' :D

Makenzie71 08-11-2004 04:09 PM

Yeah, I do...lol. Later on I'll have a pic or two of the steel valence I'm about to go out to the shop and pull out of my ass...

I wish they were a bit lower profile...but I think they don't look too bad.

Hey...I could have done what this kid did:
