Instead of building a bulky sub box,I want to fiberglass the 6x9 speaker baffles and use the Pioneer Premier shallow mount 8" subs where the 6x9's go.I have one in my truck and it sounds great,and in the car it would also save wieght and have a stealthy appereance to it.What do you guys think?

 

last summer i built a box and put 4-10" rockfords init and it took the whole trunk space in my 86 and 1 person can barley lift it,,the only thing is what r gonna do about rear speakers?? you could get a nice set of component speakers for the kick panels and a nicer amp for them and u might be fine but i think you should set in the trunk space youll have some space left and it looks cool back the too.

 

i plan on waiting for jum's kick panels to be ready to buy , i want a set but q forms suck

 

I like my mids and highs up front and the lows from the rear,if the staging doesn't sound right,I have a set of MB Quart 3 1/2" full ranges that would fit in the space under the speaker cover along with the 8's" that should do the trick.While my car is torn down like it is now,I can do alot of experementing with speaker placement to see what will work best.

 

i had to keep the 4inch speakers up fron and add pick panels to the fron of mine because the bass is too much at first i wanted it to be lound and obnoxious but i listen to rock and the bass overwhelmed the rest of it thats why i was wondering about the mids and highs

 

Rock is all I listen to also,the setup I'm thinking of is kinda what's in my truck,but I only have one 8" in my truck.I have a set of Kenwood components I'm gonna put up front along with the 4x6's,so I shouldn't be to overwhelmed with bass.

 

If you have an amp with high and low pass filters you wont have a problem,
My setup is 2x JBL 4x6's (front) running off the deck, 2x MTX 6x9 in the pillers running from amp chanels 3&4 on about 80% high, 20% low and my Single MTX 12" Sub where the back seat is running on amp chanels 1&2 running 100% Low pass (Bass) with 12db bass boost,
Now here is where you can set it for youre music type you can give the SUB/SUBS a mid range with 50% high and 50% low so the bass wont over power the rock music.

I like the sound of that setup tho, if you can get thoes 8" subs to fit in the pillers id say go for it and if it dose not work atleast you would know.

I won't have a problem getting them to fit,I think it will be a very nice setup.

 

I've crammed a set of 8's in that area before on my 88. They sounded decent but they weren't designed for free air use. I want to say they were Orions. Man I'm old LOL . . .

Anyway, You'llhave to do some cutting on the mounting area to get them to fit. I would try to find some free air 8s (if anyone even makes free air speakers anymore) and make sure the mounting surface area is sealed off. The rest shouldn't matter.


You can always just drop a sub in a box down in the well area though. I have a single 10" JL Audio 10W3v2 in mine running off a MTX TC30001. The amp is bridged and both voice coils are wired in parrallel dropping it down to a 1 ohm load. It hits plenty hard reguardless of what you listen to and has clean tight bass for rock. The box just barely rasies above the frame rails that form the sides of the well. and sits under the plastic hump that covers the hatch latch/pull down motor. You hardly loose any storage space and it keeps it stealthy. Well more so if you have a cover built for it.

 

Actually sounds like a great set up. Will you have enough volume? My knowledge of the shallows is not up to snuff. What requirements do the subs have for air space. Usually what i did (to get away from fiberglassing) was to use triple expanding foam to fill in the cavitywhere the 6X9 or whatever speaker I was mounting there. Then i would hollow out an airspace for the woofer. It tightened up the sound. Of course I had to be carefull with the foam. It could "bubble" out the outside sheet metal. That foam really expands. Good luck. Let us know how it turns out.

 

The Pioneer shallow mount 8's" only need .15 to .5 cu feet of air space to operate,so that baffle should have plenty of space in it,and I'm planning on using a mdf ring to mount the sub to the baffle.

 

Positioning your subs in the middle of the car like that will cause some cancellation at the higher bass frequencies, but nothing extreme. As long as you can build a properly rigid and completely air-tight enclosure behind the subs, they should work fine. But, there's plenty of depth available for normal 8" subs, and you can certainly get some conventional 8" subs that are better quality for the same amount of cash as the shallow Pioneers.

 

I really like the Pioneer shallow mounts,I have one in my truck and I'm very happy with it.

 

And that's fine, but just understand that you only get so much for your dollar, and when you pay for a shallow-mount sub, you sacrifice sound quality or you overpay for the level of sound quality that you get. Those subs are great when you need a shallow sub, but when you don't, you can get much better sounding stuff for the same price.

 

Well,I may have changed my mind,one of my friends at work is going to give me a set of MTX 12's" in a hatch box.He said one doesn't work,but I'll check it out good when he gives them to me.

 

i know a lot of diy'ers have had good luck with the tang band 6" available at partsexpress. not huge, but may be a good size for the area. very good for home or car use, and the price is very nice too. for ideas on enclosures, use the stock foam "enclosures" as a template for some fiberglass ones.
