after a ton of though and back and forth, looking at the pros and cons. i decided the back seat is coming out. i don't have any kids, 90% of the time its just me. the other 10% of the time its me and my girlfriend. the custom sub box was cheaper to build with more room and i now have plenty of room for a tool box in the back. to add even more space the sub box a built in ice chest holder. so for me it's a win win i plan on having the box done and installed this weekend, i can post pics when its done

Wasn't hard at all, and I'm very happy with the result.

How is this done? and what sub are you using? I am very interested in doing this! looks great.

I have 2 mtx 8s in a ported box. Fits behind my seat and have it bolted down. It gives me the sound and vibration I want. And I can be heard at red light but I choose not to. I'm also in highschool

Thank you. I used a Rockford 12" shallow mount sub. I should have opted for the 10" model but i jumped the gun a little and got the 12". There's a few guides on how to do this online, and you can modify it to suit your needs. Once you take the seat apart, you can get a visual concept of how it needs to go together. I'm not good at explaining but once I had the bare frame I made the front baffle the same size and shape of the bottom of said frame and built the rest of the box off of that. then you just cut out the foam and put everything back together. I wish I could be more specific, but I didn't keep any of my notes. but if you have any more questions I'll try to answer them to the best of my knowledge.

First of all stop thinking you have to give up back seat to have good solid bass and keep seating for 4. I do pro sound as a hobby, so I know a little about what they call 'sound reinforcement', plus I did some killer custom installs long before it got to be a whole industry.

Still in high school? Good, then keep all four seats and load 3 of them with babes and make their butts bounce with solid tight bass.

Ok, here is what you do...FIRST forget the that idea you need huge flashy subs..thise things are expensive, power hungry and just eyecandy...What you need is smarts and creativity more than bucks and room.

Start by learning all about speakers-not from modern marketing, but the actual science of it that factory engineers and pro sound guys have to learn.

Good old Radio Shack used to offer a few pamplets about speaker enclosure design that contained all the math and info necessary to make your own small sub boxes that will fit UNDER the rear seat and make the gals butts throb. You can build a killer subwoofer array using inexpensive 4" drivers that only require a small amp if you cross them properly and use the math necessary to design your box.

Good sound ain't about bling, huge speakers and lots of money, it's about smart design and math and a little elbow grease.

Start by researching loudspeaker parameters. Learn all about the terms and values and language used to describe speakers, and the math equations required to calculte enclosure volumes...From there, it's a simple matter of selecting inexpensive speakers and powering and filtering them properly....Really easy to do if you do your homework.

You will have killer sound, all 4 seats, and the bucks left to buy those gals a burger.

Promise
Listen to him, hes right.
My single 8" sub in a well tuned box and 300watts sounds better then my brothers 2 12"s and 2 10"s running on a 1000 watt and 1200 watt amp. Does my bass get loud enough to shake the car 4 cars up at a redlight? no. But people on the other side of the light can hear my music in full and crisp. So dont think you need huge subs to sound good!

Oh and to add to it, my entire sound system cost no more than 200 bucks. thats including the the head unit and amp.

I'm going to be using this 10" when I do mine.
Amazon.com: Pioneer TS-SW2501S2 10-Inch Shallow Subwoofer with 1200 Watts Max Power: Car Electronics

Pushing it with that 800 watt Pioneer i mentioned earlier which will be mounted inside of the center console.

This is one of the few mods to my Jeep that I am nervous about. I have read several threads about building this style box and it seems easy and intimidating at the same time. I hope it's more on the easy side. lol

So very true.
I had two 8" in my old Ranger and people drooled over how well it sounded.
Quality and good design will always win, hands down.

I ran those Mallets for about 6 years and they still hit hard when I sold the truck.

I did it...ended up pulling the system out within 3 months. I loved the sound...but I got romantically involved with a girl who had a 6 year old. Of course, a few weeks after I sold my amp off, we broke up. I regret selling the amp...but didn't have the time or money to build/buy a new box. Find something that goes behind the rear seat and keep room for your seat just in case you decide you need it. I had a single 10" sub in there and it hit plenty hard...you can easily run dual 10's or even 12's behind the seat and they'll sound just fine.

Pick up a Rubicon (pre-2007) center console with the bass speaker in it, and replace your TJ console and you'll have all the bass you need. And you won't lose any room at all.

My X had one of those 6" in console subs... it sucked. I pulled it out and I'm selling the box to someone that plans on putting a slightly better sub in it, but still... a 6" will never give the OP the bone rattling bass that he is looking for.

On the other hand, he doesn't need to pull the rear seat out to get it. There are several box designs available that will allow for 10", dual 10" or even the ever famous Solo-Baric....


but even this is no longer needed with todays technology in subs. The Pioneer flat subs can do 20hz with less than 1/2 cubic foot of air space.

If you ask me, removing the back seat for subs only serves one purpose, to show off your subs... and that can only lead to one thing, getting your subs stolen.
But we all know that you have to learn life's lessons the hard way...

02JeepWranglerSportTj, I wish you luck, but I am going to remember your name for the "I told you so" when you are back on this forum posting the "Some jerk stole my subs" thread.

Heck, I thought all TJ's had a sub in the console. My 05 Sport does.

I can let you know what I think of this Pioneer GM-D7500M once I get it all hooked up. I have heard good things about it.

800 watt max, Class D mono at 9-5/8" x 2-1/4" x 7-7/8"... it's pretty compact and has a very clean look. onlinecarstereo.com has them priced at $129 w/free shipping.


It's big brother puts out 1200 watts and is 12-1/4" x 2-1/4" x 7-7/8"

Some had a plastic "filler" box instead of a sub.

Here's the 10 in sub install that was done by the previous owner... I want to replace the sub with the JL I have in my parts closet and eventually move the amp where yours is mounted. I was actually wondering if it fit there... Thanx!

So how easy is it to put a sub in the bottom of the back seat?

If you put a massive box with two 12" subs right behind the drivers seat its gonna sound like absolute crap. A jeep is way too small and open for that kind of bass...the sound will be terrible, all you'll hear is the bass, and you'll just make yourself look like an idiot haha.

Do yourself a favor and and run a 6 or 8" powered sub behind the back seat. It'll take up minimal space, has an amp built in, and will produce nice, tight sounding bass thats perfect for a jeep.

Folks, we've all heard of Bose, right?

Bose showed me how easy it is to get full range sound with multiple small drivers using minimum power.

Four 4" speakers in a shallow box can be mounted on back of seat and also contain the amp....It's just a matter of selecting the right speakers and designing the box properly...No, you won't rattle the hood, but it will sound KILLER inside and near Jeep.

Too bad you're not closer... mine sounds perfect IMO (granted I like my bass when listening to my music so it's turned up a smidge, but it does sound good nonetheless). Comfy wise... uh ya, it's not comfy at all. It's like a hard, vibrating bleacher seat with a little padding, but I don't sit back there and I rarely have passengers in the back so meh.

I bet if you took the backseat out you could run a "Jackhammer"

jackhammer....that's something I haven't thought of in awhile. I never had one of those, but I did have a few pairs of the RFL's. I think the jack need something like 8 cuft or something retarded like that

I kept my backseat in, built my own sealed box that holds one 12. I have room for 4 5 quart bottles of oil to fit in the trunk still. Put the amp under the back seat. When the bass hits you can hear it from 30+ feet away. Just build your own box and you should be good.
