    I am getting two Maw-15's and I was wanting to put them in a Ported Enclosure tuned to 30hz. But I drive a 1996 Ford Taurus and I'm worried I will come up a little short on Trunk Space. Any Ideas for the box Or do those subs sound good enough in a Sealed Enclosure? Thanks In Advance Guys. ~MadroX

People around here don't know there chit so I want to show people what a loud car is compared to some of the retards around here. Ill try and get some pics up but wondered if anyone could help at all. Thanks guys. Andrew

    I'm looking to build a nice ported box for my L7 and make it loud. Problem is I really don't know much about ported boxes or the tricks to making a good SPL box. Kicker reccomends between 1.75 and 3.25 cu ft ported, but no tuning frequencys. The box will be sitting in the back seat of my 1990 extended cab Silverado. What would be differences between a round port and slot port, and what would be an optimal Frequency to tune it at. thanks for any advice, hopefully I can pull my ol' truck into s comp and put up some decent numbers

    So I'm taking my setup to a 1x event in timmonsville sc. I'll finally be getting metered on a t/l, but I'm wondering what I should bring with me, and if anyone has any tips. There are 2 classes they said I could compete in, truck/suv or something else like extreme personal or something like that. I don't know what would be better, or if it makes much of a difference because like I said, it's my first competition. I've already been told not to do anything to drain the batteries before getting metered, don't know how sound that is or not... Just wondering if there's anything I should know before driving 70+ miles away tomarrow moring. ;D Thanks.

He rides around in a big-honkin van. He loves car audio and has always been interested in what other people have. Anyway his birthday is coming up soon and I was wondering if you guys could just put your heads together and help me figure out how and where to put a system in his van. I will have pictures soon. Later Today. It's a '91 Chevy Van with the back seat cut out so he can drive his wheel-chair into it. Anyway I have to go put a water pump in. Thanks in advance for all your help and…

    ok so between my 2 15's im going to have about 400 square inches of port area, and i need to know if figuring out tuning frequency is the same as like a round or slot port. or if 400 is too much lemme know. i have figured 355 per sub so 2/3rds of that is about 220 per sub. but the box is going to be aboue 3.5-3.8 cubes per sub and i would like it to be tuned to around 35 hz. but i have no idea how long i need to make the port or anything like that. so any tips or tricks are well appreciated.

    I have been trying to decide whether or not to go smaller with my box build. All of my buddies that are a little old school when it comes to spl say big boxes are the way to go... But when talking to people I compete with such as TJ in his Yugo doing 52's he says go smaller. My current box is 3.68 cubic feet after driver displacement, but not port displacement. 69 sq inches of port tuned to 42 hz. The woofers are two TC sounds OEM 10". I am thinking of shrinking down to a triple front baffled, double walled 2.4 cubic feet gross, and using 2 4" aero-ports and slightly raising my tuning as the change in box orientation changed my resonant, and building the wall (in the trun…

    alright. ive got the dimensions. i have 2 options of building this. its kind of going to be trial and error until i find the right height i want the desk to be, but here it goes. the box needs to be 4.5 cubes each (2 seperate boxes) and tuning...im guessing like 20ish or 24hz or something? 95% of the time its for rap music. once in a blue moon i may watch a movie on it. but for the most part, i want it to sound best on rap music. the dimensions im working with are 39" x 37" (width and length) using those 2 dimensions, i need to see how high it will be to make 4.5 cubes after determining the tuning and port length, etc. if i like the height, ill build the box using that wi…
