Down Fire or Foward Fire Subs?

Hi, first I'd like to say I'm new to the forum and new to subwoofers. I was wondering if a down fire subwoofer enclosure or a forward fire enclosure behind the rear seat would be better. If it helps I'm almost always going to have the rear seat in and during the summer I'll have a soft top (or no top) and in the winter I'll have a hard top. I know I don't want a rear or upward firing enclosure. So if anyone has or knows about enclosures any help would be appreciated.

First off, bass frequency is nondirectional. Secondly the frequency waves of most bass are longer than the vehicle in question. From there your question can get quite complex depending in what you are trying to achieve.

Agree with above. Are you looking to win bass competitions or just a little something to add good sound and not beat you to death?

I know that bass is nondirectional and in an empty room it wouldn't matter at all but where a forward facing enclosure would be snug right up to the back of the seat (almost touching) and I didn't know if that would have an impact on sound quality. I don't care about down fire as far as protection goes because I'll always have the seat to protect the the subs. I'm not looking to win a contest I was just wondering if anyone had an opinion or if it matters at all. I just want some good bass in my Jeep.

With good being a relative term..... I would say look for a stock console that houses a sub. Swap the factory sub for an after market kicker sub and call it a day. That's what I did in my 98 and couldn't be happier. Didn't have to compromise space which is limited in a jeep to begin with, an everything still looks factory and thus gives nobody a real reason to want to break into my Jeep.

Here is a custom box that houses 2 10'' alpine type-r's. Sorry for the blurry pic, only one i could find. It is down firing with screw-on rubber feet. Best part is as long as i lock the tailgate, it cant be moved even with the top off.

The problem with the console sub is that is that I've already ordered some alpine subs and an amp along with the wiring. Don't worry I made sure the subs will work with the airspace of the enclosures available, and they'll work with any enclosure I've found that fits behind the rear seat. It's just down to what direction I want the subs to face and what texture/color I want.

And that down fire box with the alpine subs, are you pleased with the way they sound because that's basically what I'm going to have

Ok, that's some of the info we needed to begin with! LOL

Personally if I was ever going to put subs like that in my Jeep, I would do a down firing box. Firing against the seat you run a risk of damaging the sub IMO. Down firing will help keep them protected from the elements (especially the sun) in your Jeep.

Say I know for a fact that the subs won't contact the seat at all with a forward fire, and I always have the seat in (which I do) to protect the subs, is there anything to give me reason to buy the more expensive down fire instead of the less expensive forward fire?

Lets say for instance you have the top down and go through a quick shower or even worse a down poor!! You run the risk of rain water getting between the seat back and box and working its way to your speakers quicker than if they are on the bottom of the box. Still not entirely impossible to get wet with down firing just a lot less likely. Also if you ever need to take the seat out to transport anything then you run the risk of puncturing your subs unless you also remove the box, which may or may not be a quick job depending on how you mount it and wire everything up.

True, I guess I'll probably get the down fire box even though it costs more (I'm what some people might call "cheap"). And is that a JK bumper I'm seeing on your TJ?

Yes Sir sure is. Since that pic I've also added the stock JK fog lights into it.

I like it. I never would have thought of a JK bumper on a TJ but it looks good, and I'm glad you put the fog lights in because I was thinking it'd look better with them.

Wow. That really makes me want to find a JK bumper and throw it on. Was it a quick bolt on job that required you to redrill holes or did it take more serious modification?

It wasn't a direct bolt on but it was also not a serious modification. Just cut the stock bumper down, removed stock tow hooks, removed impact blocks, drilled holes in the stock number to bolt on the JK bumper. Had to do a little bending on the bottom metal lip of the JK bumper. I can give you more direct guidance when you get ready for it if you want. And the JK bumpers an be had for very cheap and sometimes even free. I was lucky and got mine for free.

If I wanted nice tight responsive bass in my jeep with the purpose of having some bass in my music I would go with a non-ported downfiring enclosure with either one 10" or two 8" nicely made subs. Nothing wrong with two 10" subs, but it's going to be overkill unless you run them underpowered. Though some folks like overkill on the bass.

So out of the two options you listed: Downward firing box. (As long as it has at least 3" between the floor and the driver itself). Enjoy whichever way you go!

I'm definitely interested in doing that someday but I feel like it wouldn't look good on an unlifted jeep (which mine isn't). I plan on lifting it a couple inches at some point but I need to recover from my recent audio purchases before I start on the suspension.

I wanted the two 10" because I do like overkill bass. I was thinking about two 12" originally but that's too overkill.

Ive got two "volumetric triangle/ square" boxes in the trunk space behind my rear seat that houses two 10s. They are forward facing. I like them and by putting them back there, you can put the amp under the seat.

First off, it's a good thing you went for the 10" instead of 12" because having a soft top the extra bass that a 12" would give you would just be absorbed in your soft top. And in a jeep you'll want down fire so the sound bounces off and is absorbed in your floor instead of being absorbed in your rear seat, in which only people in the rear seat would really feel. And you can also build your own box for a whole lot cheaper if you have the tools to do it with.

I could probably build my own box but I don't know if I would ever build a box that would house the correct airspace. The boxes I'm looking at are literally perfect. They allow exactly the ideal amount of air for maximum performance of my subs. And I figured the two 12's would just be too much. I like lots of bass but I also like quality. Two 12's would be too much.

Yeah, I wouldn't know about that either, I just saw a few threads where people have built quality boxes that look just like the ones on the market for jeeps

Would the back seat really affect it that much if I got the forward fire? The downfires are all at least $40 more and the subs are going to be protected 99% of the time from the seat and top.

Forward fire. That's how mine are. I worked with forward fire, down fire, and up fire in my truck when I had it. They all sounded the same to me.

Okay thanks. I don't want to pay more for something that doesn't give me any advantages. And I like the fact that you can show off the forward fire whereas down fire the subs are completely hidden, all you see is an ugly box.

I would advise against "showing them off". Keep them hidden so no one knows what you have so they can't steal it!

Well I'm not going to drive around in the city with the seat down and the top off, but I can fold the seat down and show my friends because I know they want to see it. And when they hear it they can look back and see them thumping away, there's something that's just so cool about watching big speakers.
