i always face them up. i do like the SP subs over the SQ subs. the difference is the SP(sound pressure) is more of the boomy bass and the SQ(sound quality) is tighter and better for listening to rock, and the SP subs are more for the deeper bass best for listening to rap.

i n my jeep i run a 12" Death Row from incriminator audio, rated at 1000watts rms power, powering it is a MB Quart DSC 1500.1D that puts out 1500watts rms at 1 ohm. 3^ft ported enclosure tuned to 33Hz. knu konceptz 0/1 gauge wires all around. interstate mega-tron plus battery with the big three done.


just finished the install on my system in my 2011 legacy.

its 2 15" Death Penalty subs at 1500watt rms power each, also from incriminator audio, run off of the IA40.1 putting out 3600watts at 1 ohm. put in a 4.3^ft double ported enclosure tuned to 31Hz. it has 0/1 gauge wire all around from Knu Konceptz. 2 Xs power batteries for support in the rear.

 

Holy crap man that's insanely awesome! I need my back seat so I can't run a 12. I've only got a 400watt rms amp and want to run 1 or 2 10s off it. Would you suggest running 2 250watt rms subs off of it or one 400 watt rms sub off of it? I like the bass to be precise and hit hard. I'm not sure which way to face them for that either.

 

go with 1 400watt sub, it takes up less room. a good 10" that hits hard is the DCON from Sound Solutions Audio. its a good sub for listening rock but still deep enough for rap also. it doesn't need a large box for optimal sound so its good for tight spaces. the best part is that its affordable. in a large box you can get the lows from rap but with a small sealed box is great for rock. it is rated at 300 watts rms but will have no problem running at 400watts.

DCON-10 D4

 

Face em down. I had two 10's in a custom built box that fit behind the rear seat. Down firing works best in a Jeep, especially when the top is off!

 

I totally agree on facing it down when the top is off but doesn't the sub sound more accurate when it's facing up? I feel like facing it down would ruin the precision of the sound.

 

mine is facing the tailgate. it hits hard with a softtop, but when the windows are down and or off, its not very powerfull.

but this is just a cheap CHEAP setup, so if i putt another $400 into it it probly would HIT HARD

 

mine is facing the back seat and its in a small box between seat and tailgate its powered by a 70$ 800w amp. very cheap set up but if i want mega bass ill take my truck i just wanted a little bass in the jeep because music isn't worth listening to on a stock jeep am/fm cassette player

 

I just ordered a 10 inch for christmas. I originally wanted it to face up but I cant seem to find a way to build a box that will allow it to face up and still have enough depth for the subwoofer itself. So it looks like I'll be facing it towards the tail gate again.

 

what sub did you order?

 

If I had seen your post earlier I may have purchased the dcon but being as anxious as I am, I had to buy one that moment so it'd be here for Xmas! Anyways, I went with an Mtx tr7510-22. It's a 10 inch dual voice coil 2 ohm sub. It has 400 watts rms which is what my amp out puts and the sub has 900 watts max. If not as good as the dcon, it will at least be better than the Sony explode sub I have now, hopefully!

 

fyi, the max power doesnt mean anything. as for it keeping up with the dcon, it holds its own, the mtx is a quick hard hitting sub that is great for rock.

 

Mine is facing back toward the tail gate.

 

Sounds good! Can't wait to get it and hook it up. Thanks for helping me out, I'm glad you convinced me to go with just one 400watt sub.

 

one of the first subs i had in my jeep was a 500watt 10" from audiobahn and put it in a small "hatchback" enclosure and it hit hard.

 

Whats a hatchback enclosure? And what type of enclosure do you run?

Right now I have one from walmart. Their $30 special.

I was thinking of using that same design and just making it out of 3/4" MDF, sealing up all the seams, and calling it a day. I'm not sure if a different enclosure would make it sound better or what.

 

its just a small enclosure. there are free plans on box building if you decide to build your own. or you could design your own and use 3/4mdf.

 

Ive got one 12'' JBL Sub in a Custom box behind the rear seat facing down. With a 1800 watt 5 channel amp powering the sound bar speakers(6'' Polks ) and the sub. It is by far the best sounding system in any jeep i was in. But yours isnt to bad either mike...

 

Sounds good, thanks.

And yes Ryan I know lol. Your system sounds fantastic but I'm just going for reasonable, not amazing. :thumb:

 

YJman, I have a 94 yj and I was able to fit a Q comp 12" behind the rear seat in a general "wedge" type box. I have it facing the tailgate and it sounds pretty good. You can still fell the bass when you're going about 50-60.

I'd experiment with it and see what you like best, then make it secure

btw, my amp is only 300 watts, sub is rated to 800

 

Maybe I'll go with a 12 next time then. I'm sure this won't be my last sub, but I'll have it for a while.

The sub I have now sounds decent facing the tail gate and to avoid complicating things, I might just keep it this way.

I have a box from walmart made from particle board but im not sure if I should rebuild it out of mdf or not. I hear mdf is a better material to use but not sure if it will make a difference.

 

This is what I used to have before selling it to make more cargo room. Had a local stereo shop custom build the enclosure outa 3/4" MDF and originally had only one 10" sub(ported box), then decided I liked a sealed enclosure better, so modified it by adding a second 10" sub and sealing the enclosure. Sound quality seemed fine downfiring. I didn't notice the quality of the bass any better than if I faced them forward or up or against the tailgate. It sounded best facing down.

 

this is the setup i have in the back of my jeep, and i do have the back seat removed and a bestop extendatrunk.

 

Nice set up. I would do something like that but I need my back seat.

 

Is it better to face them to the back or to the floor for safety reasons? I'm talking about what happens when the bass player detunes to 9 Hz and boosts the volume to 11, forcing the cone to blow completely out of the box (the voice coil being ejected out of the magnet in the manner of a rail gun). Or will the box recoil away from the speaker side like a gun, breaking the rear seat off and shoving it into your back?

:wavey:

:hide:

 

has nothing to do with safety. there is no speaker or sub powerful enough to blow through the back of a seat. when a speaker blows 95% of the time the voice coil burns up or breaks. there is never a projectile shooting out of a speaker.

 

Jesus... Has all sense of humor left this forum?

:nonono:

:rofl:

Please reread... Is any of that possible? Just like flaking good quality paint off the body from the vibrations? Windows would be going first.

And I'm talking about throwing the cone completely in and out at 9 times per second. It may not be a sound at that point, but it would be movement. Humor me, will ya?

And I'm talking about the bass player dropping the E string loose enough to make it vibrate 9 cycles per second, or failing that, find a full 2X4, make a string bridge from it, and put a cable on it and tighten it enough to vibrate that slowly.

 

and i have no idea what you are talking about when you say "the bass player detunes to 9 Hz and boosts the volume to 11"

"detunes"??

and 9 Hz is extremely low, almost no sound given off at that low of a frequency.

 

It takes more power to reproduce high frequencies than low frequencies. So a violent failure would be from a much higher frequency. It takes very little effort for the low frequencies so nothing would happen
