I'm looking at putting 2 sealed 12's or 1 ported 12 in the space under rear deck in Lincoln town car. The space is available is 41"W x 10 in H x 16in D. If ported is the way to go I'm going to have to the shop to build it unless you can give me plans to do so. I hate to spend $450 on box. I can do the sealed. Is it recommended to have each sub in it's own chamber(for sealed), or can you just use the whole box for both. Just want to sound good on all types of music. (metal, rap, plain rock, ect.) Any more info needed let me know. Haven't bought amp yet so will buy accordingly. Appreciate any help. I'm open to different subs, especially if they were cheaper and sound good. Leave more room for amp. Or are more in line with application that I'm trying to do.

They can both be in one chamber. One sub would be cheaper to power and you'd get approx. the same output with 1 ported as you would with 2 sealed.

I guess I would have to fire sub up to the deck, which way for port? would firing the port to the side or back be that big of deal? Can anybody come up with box design i could use.

Well, how brave are you with your car? If you're aready going to have your sub right under your rear deck, you may as well port through it. That will yield you maximum bass in the vehicle. A cutout for the speaker itself wouldn't be a bad idea either.

I'd rather keep the sub and box and ports in the trunk. Would I have to put baffles under my rear speakers too since they're open to trunk. Or would that really matter.

depending on what edition towncar it is. it may have had a factory sub... when removed it would leave a 8 inch hole in the rear deck, honesty the rear deck is so this you should not need to hack it up.

Town car cartier, I pretty sure it has a sub in back. I thought it was a 6" , but I don't know. I will look into that. I really don't trust the shops around here to do something like that. Had too many bad experiences with both. I live in Danville VA.

indeed it does have a sub... it is a 6 inch driver.. but the cut out in the back deck should be about 8 inchs,.

When it comes to town cars bigjon knows his stuff. Good luck on the build.

I would not know how to port it up through the deck. As I said I really don't trust the shops here to do it right. And at 450 to 500 bucks I want it right. I guess I will just go sealed.

you really wont need to port it THRU the rear deck.. only twored the rear deck..

but if i remember you said you listen to alot of rock.. and IMO sealed is better for rock... more or a wide range... again just my opinion

Thanks for replies. I would love to go ported , I've never had a ported sub. But I think I'll just keep it simple and just go sealed. If anybody would give me a design for 1 -12 ported with the space I have I'll build the box myself. 9.5"h x 41W x 16D. I would have to fire sub up to rear deck. If not I'll just go sealed as usual.
