CCSubaru Posted March 12, 2009 Share Posted March 12, 2009 I am purchasing one 12" Quantum Audio 3000W PEAK/1500W RMS Sub and was wondering if anyone else has a single 12" and would like to hear some opinions on loudness and vibration etc. I would like it loud and don't know if i should go with two or just stick with one. (I'd rather have one) Please let me know what you set up is and how loud it is and your opinion. Thanks. Link to comment Share on other sites More sharing options...
superasianguy Posted March 12, 2009 Share Posted March 12, 2009 Hey man. I have one JL 12w6v2 in a little box running a 300 class d (I believe) amp in my 05 LGT. It sounds really good and has enough bass but it won't shake my car apart. One thing though, it doesn't get as loud as it used to like in my old car with an aftermarket cd player but it still sounds really good. Also another thing I've noticed is that if I keep the box right against the backseat and back deck, I hear a little rattle from the back deck when it's really bumping. But JL audio makes a crossover type device that fixes the equalization problems with my model. Good luck and let me know how it goes! Link to comment Share on other sites More sharing options...
peteyjr Posted March 12, 2009 Share Posted March 12, 2009 I used a 12" Infinity sub with a JL 500/1 series amp and it got pretty loud (and clean). Currently switched to the Jl audio wagon specific Stealth box with a 10w6 , same amp. Almost equal SPL and cleaner, better transients. Location and strapping it down do make a difference (stealthbox is bolted to the chassis). Gone are my days of triple 12's . You may want to invest in a more powerfull amp . Like a 1000 watt RMS amp . You can get jl's 1000/1 used for pretty cheap on ebay. What I like about JL mono amps is the range of adjustability. They give you paramertric EQ, adjustable slope, infrasonic filter etc. Something for everyone. Link to comment Share on other sites More sharing options...
peteyjr Posted March 12, 2009 Share Posted March 12, 2009 BTW sound deadening will help with the rattles and vibrations. Link to comment Share on other sites More sharing options...

str8dwn Posted March 12, 2009 Share Posted March 12, 2009 Here's mine. Had a biotch of a time getting it mounted b/c their bolt was off angle. Also, the sub doesn't seat very well. Link to comment Share on other sites More sharing options...
peteyjr Posted March 13, 2009 Share Posted March 13, 2009 Very clean and nice install str8dwn. What is that knob above the stealthbox? Also,did you cover it in another material? I had trouble bolting it in as well. But I ended up buying a longer bolt and bolting it to the outside chasis (hidden by the taillight assembly). I also painted the enclosure to more closely resemble the interior and put a 12" grill to make it look more integrated. Link to comment Share on other sites More sharing options...
sicklyscott Posted March 13, 2009 Share Posted March 13, 2009 Looks pretty good, how much does something like that run? I was just thinking about building a box and putting it where the stock tray is. I have a few SoundStream SPL 10's laying around, was going to use one for this project.

str8dwn Posted March 13, 2009 Share Posted March 13, 2009 What is that knob above the stealthbox? Also,did you cover it in another material? Thanks. The knob is for the stock grandpa cargo nets. I covered the box originally in black carbon vinyl (as shown). I later wrapped it in black carpet. I drilled a new hole and plugged the JL one all from the taillight. I also went inside the rear fender and bolted it from that side too. If I had to do it again, I'd save cash and buy the Wicked CAS box. After the issues with my Cleansweep, my 300/4 having to be rebuilt, and the WAY overpriced box, I am done with JL. Sicklyscott, I made the tray and cover myself. Cost ~$50 in materials. An inside picture for you below. Link to comment Share on other sites More sharing options...
rexster Posted March 16, 2009 Share Posted March 16, 2009 the same sub will make much more bass in a wagon than a sedan. i have a wagon and a single 10" sub hits hard. but it would not be enough for a sedan where you have to play through the rear seats. no one here will be able to tell you if one is enough. there are many variables including the amp, box design, efficiency and your preference. I would put it in there and experiment with placement. you may find rear facing makes more bass than playing directly into the back seat. Link to comment Share on other sites More sharing options...
datrumole Posted March 18, 2009 Share Posted March 18, 2009 there are a few great subs out there... JL 10W7, has just as much surface area as a 12, and its the my favorite sub....plus go with the recommended ported box in the manual, it SLAMS (13W7 i couldnt even imagine) IDMAX 12, extremly loud and clear, very clean...excellent bump Digital Designs....SPL subs...for more bass than imaginable RE Audio makes some serious stuff too, a great line of Super SPL and Quality.... oh, and honorable mention goes to the Alpine X, pretty solid sub Dont forget, your enclosure speaks just as much as the driver, just putting it in any old box wont do....

str8dwn Posted March 18, 2009 Share Posted March 18, 2009 I did buy used, b/c I find their retail prices needlessly inflated. Agree I should cut them some slack due to this, but all equipment was confirmed to be <1 yr old. Link to comment Share on other sites More sharing options...
RedDawg Posted March 18, 2009 Share Posted March 18, 2009 any heat issues with the amps enclosed under that panel? Link to comment Share on other sites More sharing options...
frostbite3360 Posted March 18, 2009 Share Posted March 18, 2009 I had a JL Audio "12 W7 in the back of my leggy for about a year. It was in a custom ported box with a Phoenix Gold Amp pumping about 750 watts RMS. The thing was a beast. At the car show at my old school it got to 141 decibals. For one "12 sub, you can't beat it. Only thing that can hit as hard imo might be the L7 subs from Kicker. Link to comment Share on other sites More sharing options...
lewinbn Posted March 18, 2009 Share Posted March 18, 2009 any heat issues with the amps enclosed under that panel? Digital amps greatly reduce the normal heat output of the older amps. Memphis audio and Eclipse both make decent Digital amps. As far as Subs, I've stuck with JL for most of my stereos and have always been happy. My first system had Lanzars, just because I didn't have anybody around to tell me otherwise. My SPL system used PPI flat piston 15's. Man, those were fun subs. Not much for SQ, but they blew my sunroof off the track! Link to comment Share on other sites More sharing options...
dandragonrage Posted March 20, 2009 Share Posted March 20, 2009 Some good subwoofers: -Adire (out of business but can still be found) -Ascendant Audio (same, sort of - bought by Fi and changed, perhaps for the better) -Audiopulse (AKA TC Sounds) -Creative Sound Solutions -Dayton (for SQ over SPL, on a budget) -Diamond -Exodus Audio/DIYCable -Ficaraudio -JL w6/w7 -Mach5 (on a budget) -RE Audio -Soundsplinter -TC Sounds (now Audiopulse) -Treo Subwoofers to AVOID: -[American] Legacy -Audiobahn -Audiovox -Bazooka -Boss -Dual -Elemental Designs (see http://www.caraudio.com/forum/showthread.php?t=205038&page=2) -Kicker (I might get flamed for this, but their technology is ancient and the Xmax is crap, and low SQ) -Lanzar -MA Audio (not as bad as some of the others) -MTX (their amps are good though) -Power Acoustik -Pyle -Pyramid -Robotunderground (Ebay brand claiming to use TC Sounds parts, but Dan Wiggins from Adire Audio brought to light their crappiness) -Sony -Thump -Visonik Neither list is NEAR full. Just off the top of my head. My favorite subwoofers are Audiopulse/TC, Dayton, and Fi/RE Link to comment Share on other sites More sharing options...
str8dwn Posted March 20, 2009 Share Posted March 20, 2009 My favorite was this guy in my town who filled his Beetle with one 18" Crunch. Mmm...the smell of burnt VC in the morning... Link to comment Share on other sites More sharing options...
CCSubaru Posted March 21, 2009 Author Share Posted March 21, 2009 Ok so I have now decided to go with the 12" RE Audio SX series subwoofer and have done some research and it looks to be a very decent sub. What brand amp should I use on it and what RMS power should I get for the amp and also what ohm I should use if using the RE audio DVC 2 Ohm (crutchfield says use 4 Ohm amp for this job) Link to comment Share on other sites More sharing options...
dandragonrage Posted March 21, 2009 Share Posted March 21, 2009 Are you going to put it in a ported box? It's not recommended for sealed boxes. You'll need to have a properly tuned box for it to sound correct. If you don't want to deal with that, then you should get a sealed setup and choose a different driver (driver is a raw speaker in this case). Anyway, my favorite low budget amps are Kenwood and Hifonics Brutus. Let me know your budget if you want to spend more and I will give you suggestions around that price.

Pick up a single RE SE 12".. you'll be more than happy The SX is not for a sealed enclosure so plan on taking up some trunk space for the Sx in a ported box Trust me.. I own 2 SEs, two SXs, and two XXXs..

CCSubaru Posted March 21, 2009 Author Share Posted March 21, 2009 I was planing on using a Ported box that is almost perfect for the SX series and am not worried about trunk space. The box is 2.0 cu ft and is tuned for 32 Hz which is one Hert lower than what is recommended on RE Audio's site so I think that should do the trick. Are you going to put it in a ported box? It's not recommended for sealed boxes. You'll need to have a properly tuned box for it to sound correct. If you don't want to deal with that, then you should get a sealed setup and choose a different driver (driver is a raw speaker in this case). Anyway, my favorite low budget amps are Kenwood and Hifonics Brutus. Let me know your budget if you want to spend more and I will give you suggestions around that price. As for the Amp my budget is anywhere basically from 150-250 and would like it to be pushing at least 750 RMS Link to comment Share on other sites More sharing options...
dandragonrage Posted March 21, 2009 Share Posted March 21, 2009 Kicker ZX750.1 new from Ebay. Their amps, unlike their subwoofers, are pretty good. Or the Kenwood 9104. Link to comment Share on other sites More sharing options...
CCSubaru Posted March 21, 2009 Author Share Posted March 21, 2009 the kenwood amp looks good but the 4 Ohm power output is way lower than what i want. (RMS Power Output @ 4 Ohms : 500 Watts x 1-Channel) Is there a way to hook up the RE Audio Dual Voice Coil 2 Ohm with one mono 2 Ohm amp or do i have to buy a mono 4 ohm?

frkkevin Posted March 22, 2009 Share Posted March 22, 2009 get an amp 1 ohm stable.. run the coils parallel.. the amp is a very important part so don't go cheap.. for $250 you can buy an audioque 1200d.. i'd suggest that route or pickup a used elemental design nine.1 i would run 1000-1500rms of CLEAN power to that sub.. i've even used more and the box you speak of.. tell me it was built and not a prefab? 512whp/465ftlb 2005 5EAT Legacy (Build Log) Videos - - Link to comment Share on other sites More sharing options...
