    The dam thing didnt fit again, lol, but we took it apart and put it in seperate. The subs definitely move alot lot more, only thing is its louder but only in the trunk still , and now its flexing the side panels and trunk is now rediculous. i wish i still had my friends camera.. I'm hoping if i can stop the flexing the sound will go into the car instead of rattling out. ANy thought.s.. BTW the box i'm pretty sure isnt done right, but oh well for now

    Since soon I will be installing a new sub in my truck (if i can ever get in contact with nick at IA) so while i have the 180lb behemoth out of my truck i figured I'd slap the leftover second skin somewhere. Im looking for the most quiet and the most potential SPL gain. My doors have 1 layre on the door skin and 1 1/2 on the door (didnt botehr putting a second layre over the window acess gap incase i ever need to acess the window) I have 2 on the back wall and that helped a LOT. It went from slapping my bedliner to maybe 1/2" of movement full tilt. I feel much more comfertable upping my SPL now that my back window isnt dancing...as much. The floor and firewall would proba…

  4. some one give me a little feed back! ive always thought it was best to give each sub its own chamber then slot port in the middle? lately ive seen alot of boxes where the speakers are pretty much sharing one chamber and L-ported towards the drivers side firing back, is this more effiecient sounding? or is this done so the box can fit better? i have a 2002 accord and i want this setup to be good DAILY. dnt care so much for SQ but more so SPL. meaning SPL to the ear ill doubt i ever see a meter. THANKS FOR ANYTHING GUYS

    I like to think up things i haven't never seen done so let's get some opinions in here because i wanna see what people think how this would work - I don't feel like drawing a pic so i'm going to rely on your visualizations to see this box in your head. Let's take a 12" sub. Let's put it in a ported box at 2.5 cuft. Tuning... thats the interesting part. Ok, so build a box with 5 walls, not 6, 5. Leave the rear wall completely off. Now, let's say for quick number crunching, the box is as follows - (all external) 16" wide x 16" tall x 16" deep with no rear wall. Now, let's build another box with no sub cut out, again with 5 walls, not 6. Dimensions for this box is as foll…

    Single Q12 going in 2005 jimmy and was wondering if I should just go with the cut sheets found here http://www.soundsolutionsaudio.com/forum/topic/44520-q-series-cut-sheets/#entry701997 or should I get someone to design one? wondering if this would be optimal for good SQ over SPL. Should I place enclosure against front seats facing sub backwards, upwards, towards front or behind back seats facing up or backwards ?? Looking for SQ quick response over SPL. Wanting ported for better power usage and also heard ported can sound just as good as sealed so went that way and got without high QTS. Anyone have experience with single 12 in SUV ?

  7. Hey everyone, I have a dilemna. I want to throw a nice pair of 12s (or 15s if I could) in the back of my trailblazer, but I want to save space. I have 2 young boys and I need to haul a lot of stuff sometimes (golf clubs, snowboards, etc). I have a Sundown 2000 that should be delivered in 2 days, so I want to work around it. Quentin from Audibel is going to be building the box for me, thus I'm pretty much looking at SSA or IA subs. I'd love a pair of 15" Xcons, but you do what you gotta do. I figure I have a few options. Either a box up against the back seat(rear-firing?), or a false floor(firing up). I'm open to suggestions. For the box against the back seat I was leani…

  10. Started by ungodlyrooster,

    I am currently in Iraq and cannot measure my doors. I drive a 2004 Ford Focus sedan. Does anyone have a Focus or know the mounting depth? I have some MLI-6.5s but they were incredibly inexpensive as I got them used from a friend and I would have no qualms with not using them. I really would like to know if I can fit the Peerless SLS 8" in my doors. I know 8"s fit diameter wise, or at least they look like it from here: http://www.cardomain.com/ride/9621. It would be awesome to have enough low end up front that I could put my RL-i 10 in a sealed box to save some space or even do away with a sub together.

    2 12" type r's at 1000wrms 1ohm ported. I'm upset with my box, it kinda sucks. The port wall isn't tall enough, and it's a little too big. I want aeroports for some reason, they've always caught my attention. I've also heard they sound better. Max dimensions are 14.5" height 26" length 37" width all external. I want the subs firing up and the ports going back. This box will be in the back of a '93 Range Rover Classic LWB. I can get pictures of the inside if needed. All daily use. Just need the box design, and cut sizes.

  13. Started by acschank,

    The site lists 1.8 cu.ft. for the IXL 12 SL. I am assuming this is for either home or car use, so would a box approximately 1.52 ft3 with pollyfill be adequate? More specifically my dimensions are: 17"x15.5" top/bottom 15.5"x11.5" r-side/l-side/inner baffle 17"x13" front/back internal: 15.5"x14.75"x11.5" This is attempt number 2 for a box. I needed some mdf for door speaker baffles and had to buy a whole sheet so I figured out all the numbers for a 1.35 cu.ft. box because thats what i remebered and had it cut at lowes today (actually I have enough for 2 boxes that size). I got home to make sure i remembered right, and of course 1.35 is for the icon, the other sub I was t…

    Hi, I am getting ready to switch my system from my firebird to my truck, so I can sell the car.. It's going in a 99 s10 ext. cab xtreme.. I have 1 12" pioneer premier 3002d4, It's in a sealed box now, but I want to build a ported one for it. I will be using a precision power 1500 amp at 2 ohms, so roughly 1000 watts to it. I know how to do the wood work, but I am not near as good with calculations.lol. A good slot port box design wood help a lot, if anyone has the time. I would like it to be tuned to 34hz, with 1.7 cu without the sub. For room in the back of the truck I have 14 1/2"x18 1/2"x50".. I know thats more than enough, but thats the total space I have.

In all of my sub setups (total of 4) it seemed that my very first enclosure "folded horn" box which is what the salesman told me it was. . Was it actually a folded horn box, I have no idea, BUT according to everyone else apparently you could hear me about 5 blocks away with two 10" memphis subs 250rms each. That box seemed the cleanest i've ever had and it had the port in the middle of the box with a wall in the middle of the port running parallel with it, so basically each subwoofer had its own chamber.

The event will be rescheduled for some time in April. The next IASCA show will be February 15th at Beach Autosound in Huntington Beach, Ca. I apologize for any inconvenience this may cause any of you. Please try to spread the word so we don't have people driving in from out of town to show up at an empty parking lot. -Todd Woodworth
