I've got a 12" subwoofer in a home made box right now. It sounds great, but I want to get rid of the box and have more room in the back. I'm thinking of changing out my speakers in the suicide doors, widening the speaker holes, and installing 8" subwoofers. I currently have a pioneer 240 watt amp that I'd use to amplify the subs.
Has anyone done this before? Or anybody familiar with the area behind the door, will it sound alright if it is not sealed? I do not need a whole lot of bass coming out of them, just lower bass than what I get from the 5x7's.
Any help would be appreciated.

 

its been done before. i had pics cant find them now tho. search cardomain. the 8" subs were all glassed in, looked sweet, but i dought the rear seat will work to good after the subs installed.

 

I'm just looking to see if I can replace the stock speakers with subs, no other fabricating (for the moment). The rear seats should still work fine with that.

 

it will more than likly sound like crap

 

ok, how so?

 

these are just my observations, im no stereo expert.

i wouldnt think the air space would be right.
it not air tight
rattles like crazy with just the stock speakers
plus you have to figure out how to run your big speaker wire to the sub.

 

I agree on the airspace, but even so, the stock speakers use that airspace, and all I am looking for is some lows that the stockers don't put out. As for the rattling, there is none whatsoever back there.
I'm thinking if the air space is really going to be a big problem, I could try to fiberglass the space inside the doors, but I don't know much about fiberglassing, nor how thick it would have to be. For the wires, they don't have to be too large for that amount of wattage, and I could run that through the gromet to the door where the old wires would be.

 

my pioneer 6x8s hit pretty hard for just speakers, why not just get some 6x8s and mount them back there and run an amp to them. ive heard if you power all your door speakers it makes a world of difference.

thats my plan anyway. power the door speakers 6x8 pioneers in the back and some polk high quality 6x8s in the front.

 

did you have to cut anything out to fit the 6x8's? Currently I have infinity 5x7's and they don't give my much bass.

 

a 5x7 and 6x8 are pretty much the same thing most speakers will even have both labled on the box as for the 8's you could get a free air speaker that would sound ok back there but not as good as a sealed box one would

 

Thanks for the info Zach and Daniel. I'm going to research open air speakers. Any other info would still be appreciated.

 

i say get some 6x9's... i think robin added some... they give off a good amount of bass but still give you high frequency sound...

 

y dont u try installing some components?

 

I know i see these 6.5 subs from companies like JL Audio, take a look at them.

or

6x9's with 100 rms should be nice.

 

I'm not going for components, because i'm looking for lower end bass that I don't believe a 5x7 can put out. As for the 6.5", I think the 8" should be able to produce more lower end bass. Please correct me if I'm wrong. I'm accustomed to hearing bass coming from a 12" sub, so I don't want to lose too much of the low end bass.

 

i dont' feel like searching..

EDIT: I'll search.. and maybe start a post.

 

you have to take out a ring thats on the speakers.... ill try to find robins cardomain its on there...

check back in this post in like 5 mins ill edit it...

EDIT: thanks, haha

 

Thanks for posting the link to Robin's site. Does that mean you think the range of bass from a 6x9 should equal that of an 8" subwoofer?

 

1. Not in a box
2. Mounted to metal. You cant match wood for down low.
3. 2 subs playing which are facing toward each other, on opposite sides of the car. Will battle each other out constantly.

I honestly dont think there is enough space behind there to make a box of the right size that will sound halfway decent.

 

you could always cut a coulpe holes in your floor and mount your subs like that one dumbass hahah. seriously though just get some good 3 or 4 ways and amp them.

 

ive actually had a pair of 6.5" subs in a past ranger that i owned. they sounded decent, but they definitely didnt hit the lower bass. since then, ive had 2 12's in a car, and a 10 in my truck now. and the best sounding one ive had so far is the 1 10" sub. it hits low bass and the quality is great. maybe you should try to find a 10 with a small box? hmmm... just a thought.

 

I wouldnt do that. For the obvious reasons listed already:

No airspace
Leaks
Rattling

I would do like mentioned above and go with a 10" in a small box. I actually have a 10" Pioneer in a small truck box that I had in my single cab ranger. I will let both go together for $50 shipped

 

And by the way to the guy up there about not having enough space for a good enough box..I have a 12" Massive in my single cab now with a box to the size it needs. It has atleast 1 cubic foot of airspcace.


of course the passenger lost a lot of legroom but thats not my problem. I have more than enough room :)
