I have a 97 accord sedan, I running a alpine hu I have 3 JBl BP series amps. the 80.4 for my highs and Im running the BP 1200.1 per sub. As for Subs, I have the MKII 12's Brahma's (2) in a 1.75 cubic feet box I think tuned an 30hz. I don't think it hits hard enough I haven't had it tested yet. Im looking for some suggestions for a new setup to get a deeper and harder bang. Could someone help with some ideas, even if I have to use the whole trunk im fine with it

okay simple enough for the knowledgable ones, IA's 187 12" subs, port up, subs back, going with 4.5 cubes and tunning at 34hz. using 4" aero ports (4"X17") =how many, how long? the one who answers this will receive good fortune for the rest of his days! thanks chop

i had an idea similar to these enclosures for my next project and i was wondering is there any downside to having one built like this?

hi, i planned to do a wall setup and the vehicle will be a 4-door Toyota Landcruiser. The wall will be as close as possible with the front seats but not up to compromising seating comfortably. How do you seal off the portion where there is window? i see that the front wall will be sitting halfway of the rear passenger door window. thanks

ok so i got a 2001 4runner and i need a box for a 10 downt know how much watts or even what sub yet but would slot ported be my best bet for a daily want to hit all notes but 33 or 34 hertz will be my bottom end what i want any help would be appreciated

I know some cars are louder facing back and some facing foward sealed from the trunk. i was wondering if anyone knew what was best for an 04 hyundai sonata? i was looking at a 15in or an 18in with between 3000-3500 watts depending on which amp i deicide on. looking for loud daily.reason for one sub is cost. thanks alot.

Alright, so my boss finally warming up to the idea of making a wall in his Cavalier for our shop demo car! Now, this isn't 100% going to happen, but I'm excited and want to be ready for when he decides. I know this place has a ton of knowledge, plenty and plenty of people who have made walls. I guess I'm looking for just general rules and/or tips to make sure it will turn out well. Iv decided just to make a normal, flat and vented wall. Leaning towards 4 15's with a nice big slot port on the drivers side. Any tips are welcome of course, thanks guys!

I currently have my sub in a poorly designed enclosure accidently tuned to 53hz. Im going to have my dad build me a new one for my birthday. I designed one using the RE calc and came out with a "classic" L port box with the sub and port on same side, tuned to 31.5hz a 4.03 cubes. I want to have the sub facing up and the port back though because i use my trunk frequently and am paranoid about my sub. My question is how would i go about designing this? The total dimensions for the box i designed with sub and port same side are 26" W 21" H 20"D. I also was wondering how this would affect the sound and volume. Thanks alot for the help.

I was looking at the 4" flared port tubes. I don't know too much about them but how do you find tuning for your box with them? And how much do they displace?

I currently have 2 fi q 15s in my dakota and am now getting a Ram 1500. Is it possible to get these sub in there or will i have to settle for what everone else is doing and go with two 10's?

Anyone from the Long Island NY/NJ/CT Area want to build me a sealed enclosure for 2 12s - or know of anyplace that would? I'm not looking for anything extravagant, just something ~ 1.5 FT^3 per chamber. I don't have the time to do it myself (and I've never made one). Trying to stay away from pre-fab junk. Shipping or Pick-up is cool. Can someone help me out? Thanks, Snapper

Ok. I've had 2 12" kicker l7's for a while, but blew one due to shitty setup, and not knowing anything and clipping all the time. Now that I've matured in car audio and have learned to respect the sq and not just bump myself stupid, I decided I wanted to go back and find out what the L7 is actually capable of given the right box. Now is where the trouble starts. I have no idea where to start building a box. I really have no idea how to either. Right now, the two subs are in a prefab dual ported chambered box and that is all I know. One sub is blown too, and I have no idea the tuning. I really want to build a new box. I'm not asking for step by step directions, just some …

Can I get away with using a single 4 inch port for my Icon 12? I don't have enough room to get 2 ports in due to the length. Lets assume the box is 3 cubes after sub displacement. Can be made smaller if that is optimal.

Alright well my buddy has a misubishi eclipse with 2 12" alpine type E's in it right now. He ordered two more today. So I dont have any dimensions but I want to make a ported box tuned to 31 hz. And probably 6 cuft. But should I make one big box? Or should I seal off the subs?

What is the minimum number of yellowtops needed to run a Sundown 3000d? I've still got the stock alternator in the Frontier and want to see what I can do. BTW the Opti 50C is up for sale.

After searching for a subwoofer I have decided on the DCON 12" it seems perfect for what I am looking for. My question is regarding the box I saw the recommended plans were 2.25^3 at 30hz I think but I have plans already for a 2.5^3 box tuned for 35hz. Would the sub work well in that box or should I scrap it and just build the recommended one. I also have a 350 watt alpine amp, would it be ok to run the dcon at 350 watts? Thanks in advance for any advice/help. - Alex

Looking for a tutorial or some instructions on how to build the covers for door pods. I can build the pods, just was wondering how to go about making custom grills/coverings for the pod. Thanks for the help

Anyone done a fiberglass build in a mazda 6 sedan? I have this idea of putting my 15" ssd in the center, behind the seats, with two 6" aeroports (one on each side of the sub). This would be firing into the cabin. I have my rear seats down 90% of the time, so I would imagine it would sound great. Anyone done it, or know how? I am looking for someone to take on this project for me, as I have never done it, and wouldnt quite say I have the time to do it either.. Anywho, im in Keller Tx and if anyone is interested I am willing to pay. Im looking to stay in the 3.5-4 cu ft. range, tuned at 33-35 hz. Im rocking a 08 mazda 6 sedan (not the cool hatch model). If you need anymore…

I'm considering building a down fire for 2 D-CON 10's. Will be subs down,port back, box against back seat. Going in a Land Rover. I only cosider this because I do use the cargo area often and want keep the subs out of harms way. My question is how much room do I need between the floor and the woofers???? And should I just elevate the box by the end plates or do a 3sided lift leaving only the rear open???? Or is it a bad idea all together???? Is a daily thumper setup.......just want to keep my investment safe.

I have a question about ports. I am having finely decided to use round ports. But I have a problem; I have 8.89ft3 I want to tune around 38 Hz. The problem I run into is I need like 15’’ of port. The box is only 14’’ deep, going with 2 8’’ ports. So, can I bend the port with a 45? So it will make it in to the car with out a problem. If yes, do I have to add any thing to the length, or do I just cut the tube where it needs to be and add the 45 in between the cut peaces. Trunk setup subs up, port up going thought the rear deck.

Looking to hear peoples experience with this set of components. Can't hear them but want to know how they sound for sq.
