    I just purchased a used 2007 Lexus ES350 which has a factory 10" subwoofer on the rear deck. It accomplishes some midbass, but just doesn't fill the cabin like I'd hoped. I want to install a Sundown SA-12 along with my existing Rockford 1000bd (I won't have it turned all the way up most likely). While I realize the RF Amp probably isn't best at a SQ install, I'm hoping the Sundown can fit the bill. My question is: Is it possible to make a box that can fire through the fold down armrest in the rear seat or up through the deck? How complex would something like this be in order to eliminate the loss or sludgy sound of bass firing into the trunk? My main reason is to try and…

  5. Whats up SSA. Im currently in the middle of my full system install and just took out the stock speakers today. My car has stock 6.5 Infinity components in the doors (woofer and tweeter mounted seperately) and it looks like it has a decent speaker mount/baffle whatever it is called. On the inside of the mount it specifies that it is composed of Polycarbonate with 10% Glass Fiber. I will be replacing them with a JBL P660C component system and was wondering if I would have good results using the stock speaker mount to install them. The new speakers are considerably more powerful and I will be sending ~120watts to them, I imagine the stock ones were seeing less than 45. …

    I'm gonna be helping a friend build a box for 2 cvr 15's. It will be in the trunk of a 4 door saturn ported through the rear deck. I haven't played with cvr's much so im not too sure how to get the most out of them. Space is limited so i was thinking maybe 7 cubes with 112" of port tuned around 50. Starting it this weekend and could really use some help. Anybody have experience with these subs in different boxes?

    I am quickly becoming overwhelmed trying to plan a box for my BTL. I want to rebuild, as my current box is water damaged and pretty ugly at that; not to mention, it's tiny; 5cu @ 34 before displacement, and the port is small as well, 4" x 15.5" (it was free with my woofer) My max dimensions are 34"x26"x23", and i'm aiming for a pretty low tuning, thinking 28-30hz, I like a lot of slowed music, Decaf, etc. I have a local builder, but I haven't seen any of his work in some time, so I'd feel better walking in with a design in hand, and simply having him make the cuts and assemble it. It'll end up in an SUV, so I'm thinking sub up port back, same as my current box. Would…

    Hey fellas. What's going on? Alright, heres the deal. I picked up another CVR, so I am now in the process of deciding what I want to do with the new box for the 2 CVRs. This setup is going to be a pure daily driver, no competing or anything. I listen to all rap or hip-hop. Now, I emailed Kicker and asked what they thought the best daily driver box would be and they sent me some specs that ended up being tuned to around 40 hz. I thought 40 hz is pretty high for daily driver tuning. I PM'd Polecat and he said that 40 hz would be good and that I wouldn't lose much low end and that it would get loud and sound musically good. My current box for my single CVR is 34 hz and I am …

    So here it goes I seen a thread where someone used two of these for this but I have lost it and cannot find it. I am interested in doing one of these setups in a sunfire. I have a15" soundsplinter Rlp but don't want to take up the trunk with a large enclosure. The IB setup would leave trunk space and be pretty cheap as far as the woofers go. I have a sundown 1500 SAZ to power them and know I would have to be vergil with gain settings......anyway any input is much appreciated. I have read the thread from Onebadmonte twice now and I think this should work good just looking for extra info before I order the woofers.

    Ok guys, I'm gonna need some help with an enclosure. First, some background. I have a friend who everyone had him talked into buying the usual kicker stuff, but luckily I got to him in time. This will be his first setup. Anyways, I coached him through buying an AQ2200D (could have chosen a better amp, I know, but his budget was sort of limited and we didn't feel like going through the hassle of looking for used deals on others), an 18" DC Lv5, and all the other bits. Should all be getting here by the end of this week. Alright now to the enclosure: The vehicle is a 2005 Tahoe Z71 (captain chairs in the rear). Now I measured awhile back, but if I remembered right, it should…

  19. The magic numbers for the DCON 10 seems to be 1.25 cu ft, tuned to 32hz. Does the vehicle really have any significant play on that? I don't compete or anything. I just hear this thing really performs with little power. I've got all the components of my budget system except the sub and box. For some reason it's the hardest thing for me to decide on. I really wanted to get away with a prefab box, but they are all tuned around 38hz. What's the point of buying a decent sub if you're not going to maximize it's potential? Anyway, As far as box building goes are there any walkthroughs or step by step type guides? I can figure out all the dimensions and cuts but the assem…

  20. Started by crazyj23,

    My original box was the one recommended from ssa and it sounded good but the wife wants more space in the trunk so I have to do something different. So I need a box with less depth preferably ported still and a little longer tuned to 32hz. I don't understand how to use the box calculators I have found. Heres what I have to work with as far as area: 32"long x 16"high x minimum depth of the sub which i'm unsure of. The sub is 6" deep so I'm guessing a 1/2" more than that is minimum Basically I just need a longer less deep box that will still sound good. I listen to mainly rap/hiphop and some d&b. Any help would be greatly appreciated.

    I am the fortunate owner of a 4th generation camaro :-p Anyways I have a dcon 10 on the way with plans to add a second. Ive seen the box plans for optimal ported and they look fine but because my box is going to be 3 sections with a wedge on top I dont even want to try to do a slot port. If anyone could just give me the size of the box and port ( to achieve the same result as the optimal ported enclosure ) with the port volume already included I would be very thankful

Could i get some help on how big to build it / all of that kind of stuff? like dimensions, volume, ported size. i might take it to a local audio shop and have them build one but i don't know what sizes and stuff.

    So, I bought 2 12" DCONs and I'm currently building the box according to SSA's . I was wondering how I should go about building the front. Some websites suggest countersinking the subs so they are flush. I'm wondering what the correct design is for the actual SSA tech drawing. I'm sorry if this has been answered here before, I've searched and searched, but to no avail. I do plan on doing a build so that other people wont have much trouble. Thanks,
