|BreckenridgeYJ||Last thought. Make sure the enclosure allows the seat to fold forward..... I have to modify the one the previous owner installed as it will not allow the seat to collapse (to be removed) when the cargo space is needed empty.|

|FirehawkTJ||I had two 15's in the yellow jeep in this picture. I removed the backseat and even went as far as bolting the box to the floor and used special screws in everything so some yahoo couldn't steal them out. I ran that setup for about a year. I finally took the sub box out and put the seat back in. Best idea ever. It was great to have that rumble in the back. Totally not worth the lack of space the jeep is limited on to begin with. I went back made a custom box for two 12's behind the rear seat. Sounds good but was a ridiculous, yet fun install. You are only limited to your skill and imagination.|

Maybe you should worry about your own education instead of Laughing at others.... Just because someone likes loud music doesn't mean they are uneducated.

I have 2500 watts of Jl amps, a 12w7 and diamond audio hex components/tweeters in my Range Rover. The entire vehicle has been dynamatted to eliminate rattles and such. After significant financial investment into the install I'm finally content.
That said, my jeep has 2 6 or 8" subs and decent mids throughout. Nothing special or flashy, and plenty of power. If you ever want to leave the top off, you have to consider likelihood of theft and water damage to the components. The louder you system, the more likely someone will hear it and the more likely they will unzip and climb in to relocate it to a vehicle of their own.
I am very pleased with the 600-800 dollar system in my jeep. It's plenty loud and with the lack of acoustics and overall ambient noise level in the TJ's it sounds good enough.
My rover started with a 10w7 and 500 watts..... This drowned out the rest of the stock system. After upgrading the rest, sub wasn't getting pushed properly and the fiberglass enclosure was a hair off for optimum performance hence a larger sub and double the amp. Long story short, that balance is very difficult in a tj. Unless you simply want spl levels (loud).... And don't care to even know what the song is your listening to, build a sensible sized sub enclosure and retain your rear seat.... You would be surprised how loud 2 6 or 8" subs can be in a vehicle that small.

|Gouch_07_X||Have my backseat out right now for 2-12" kicker cv r's hit 140.1 with them. I am taking them out and putting in a 12" solo x ( guy I am getting it from hit 161.0 ) 5 channel amp with it not sure in te size, go big or go home boys the box will take up prett much the entire back, will be slapping a sheet of plywood over it to make it 2-tiered so it's not fully useless back there|
|02-24-2013 12:39 PM|
|smolder||a 4x75 amp under one seat, and an 8" powered sub under the other sounds suprisingly good.|

|mike25||im currently putting my 2 12 inch west coast custom subs i have in a 13 inch box in the truck without removing the seat i have to cut the box down a little so it will fit but all the measurements add up im putting it in today ill let you know how it goes. it's the best thing you get to keep your seats and have sick bass. get the correct size box and you can fit anything in the trunk space man don't ditch the seats because whoever is going to sit in the back seats with the subs cranking it's gunna be BLOWN lmao|
|03-22-2012 07:15 PM|
Just like Dragonii said, I have 2 10" 2 ohm speakers with 1200 watts pushing. They fit behind the seat and make pleanty of deep bass. I like my music loud but only when it is appropriate. Like alot of the others guys have said loud rattling at a stoplight is not cool, so just be respectfull when driving in town.
Definetly dont lose the back seat just for subs.

|Ibuildembig||True dat....I have been in the car audio business professionally for 14 years now and it has gone through alot of changes. I have built them all, SQ, SPL, dB drag, Iasca, USAC, demo cars etc.....everyone likes different stuff. I am old and still like like the boom from time to time; but I have a remote gain so I can attenuate it down when its not needed|
|03-22-2012 09:39 AM|
I think the main focus of this thread however was the subs, and there has been huge advancements in car audio subs in the past few years that make it rather foolish looking to drive around with enormous boxes that take up the whole rear of your vehicle. Unless you are in a competition, it just makes you look like this guy.
|03-22-2012 09:22 AM|
|Ibuildembig||Sorry man but 4 4" drivers will do nothing in a car. Its not a home theater or a recording studio. I was able to achieve the same SPL as 4 15's with 5" drivers about 8 years ago, but it took 25 of them to do it. The other thing you have to keep in mind is that 90 percent of your home and pro audio transducers sound the way they do because of the cabinet design. That being said, its nearly impossible to have a perfect cabinet design in a vehicle, much less a jeep.|
|03-22-2012 09:16 AM|
I personally follow your train of thought. I have two 5.25" 2-ways in the front, two 5.25" mid drivers with separate tweeters in the pods. For bass I will being using a single 10". I have found over the years that a 10" is pretty much the perfect sized sub.
Same theory goes for my home audio system.
I had a set of tall floor standing tower speakers with 8" subs in them and I replaced them with these.
Each aluminum cabinet contains two 4" drivers and a tweeter... and they scream. They make the three foot tall floor speakers sound pathetic. On the side is a single 10" amplified sub and it will rattle the pictures on the walls.
Large is no longer needed. The 10" sub that I am putting in the Jeep has a mounting depth of only 3" and running at 2ohm with a max handling of 1200 watts, capable of hitting 20hz.... sit too close and you may poop your pants.

Let's do a little math A= P x R squared
Now calculate cone area for 4, 4" drivers VS 1, 12"
That stated, remember that the idea is to move air, and more cone area moves more air, right?
Ok, now consider that larger cones have to be stiffer with bigger magnets and take more power to move. PLUS they require a higher quality amp with better dampning to control the cone. PLUS, the larger driver is also measures deeper. PLUS, you can buy 4, 4" drivers much cheaper than one bass worthy 12".
Bass freqs can be the very hardest to reinforce and control, and also the most expensive band in the whole freq range to reproduce if you don't use yer head.
Useable bass freqs for playback of most if not all prerecorded music is only 50-150 Hz, and considering the male chest cavity resonates around 85 Hz, then focus your efforts on cheaper, smaller drivers that are very efficient in that range.

|TjTheo||Here's a pic of my custom box, not much of a looker but it bumps.|
|03-21-2012 01:51 PM|
|TjTheo||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.|

|Ibuildembig||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|
|03-21-2012 01:34 PM|
I bet if you took the backseat out you could run a "Jackhammer"

LOL we have a saying in the 12v world...."No highs, no lows? Must be Bose"
Really its all a matter of opinon and everyones is different
|03-21-2012 01:12 PM|
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.

My one lonely 10 gets the job done and I have the seat for the kids!
|03-21-2012 10:22 AM|
|Ibuildembig||I disagree, it can be done....just takes a professional to design it|
|03-21-2012 10:13 AM|
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.
|03-21-2012 10:10 AM|
|Ibuildembig||I wouldn't do it...it ruins the seat and I haven't heard one yet I was impressed with.|
|03-21-2012 10:06 AM|
|TJspeed||So how easy is it to put a sub in the bottom of the back seat?|
