SPL & SQ / Fabrication

I have an old 2 channel amp that i wAnt to put in my truck. Should it go on tye front door 6.5s or on the back door 6.5s? My sub is in the back seat also... But what would sound better? Iv been told the back would sound better... But i feel the front would. What do you guys think? They are the kicker ds series 6.5s and its like a 40rms amp or so per channel... Coment please!

I'm almost up and running with 2 sa10's on a sundown saz-1500d @1ohm in my Lincoln. I have a box I built for my Cadillac, that is 2.5 cubes with 40 sq in of port area with a slot port. I'm going to run this for now, down in the well of the trunk. Here's a pic. I want to build a new box that sits on the hump behind the seat. I'm not going to run rear fill or the factory sub. So I will have two 6x9 holes on each side and a sub hole that is 6-8" in the middle. First question is what size aeros to run. Will 2-4" or 1-6" be enough port area? Or maybe 3-4"? Second question, how to port through the rear deck? The box will be 10.5" tall and the bottom of the rear deck is about…

Okay so i already had a box designed before but i wanted to try it all on my own...thanx to the12volt.com box and port calculator i figured out a simple box i can build...here are the specs BOX: W-47" H-25" D-28" PORT: W-30" H-5" D-10" The box will be 16.4cu ft and it will be tuned to 35hz...the port will be facing back with subs fired up/inverted...

Starting a box for a friend tomorrow. He has 2 12in kicker cvr's in a prefab box with the ports stuffed with towels because it's way to small to be ported. Lol I will be building a 5 cu box tuned at 32hz. Dimensions are 36w x26d x15h, port is 5in x 13.5in and around 26 in long. It will be 3/4, double baffled and 1in dowel braced. He doesn't have much power JLa1400 (500rms) Should be good for when he can get some real subs and a bigger amp. It's going in a Cadillac deville trunk rear facing. Opinions are welcome., although after spending about a hour making the cut sheet I am pretty set on it, lol. Can post pics during build if anyone wants to see it, should be a huge i…

Starting a new box build this weekend. I'm doing a slot port for this one. The box is 23" long with a 2.25" wide port. Need a 27" long port to tune. According to my math, the L section of the port needs to be 4" long. This assumes 2.25" from end of box to edge of long port length which I come up with 20.75. Taking center of port at 21.875 that leaves me with an L of 5.125 center. Subtracting back in 1.125 of center leaves me with 4". For end correction, I need to add back in 1.125 which brings me back to 5.125" L I've had a long week. Is my math correct? I don't design a lot of slot ports. Thanks! Dave

So im building my first box out of 3/4 mdf...what size bit and screw should i use? Also whats the best glue i can get...money aint really a problem right now so give ur .02...

Howdy, I am going to be walling the astro soon and wanted to get some ideas of what type of walls there are and whats the benefits to them.I am walling it with 8 18" icons I havent set the amp in stone yet but I am contemplating between a DC 12k or a Soundigital 16k. once again the amp is up for debate. There will be a multiple alternator setup with battery bank to supply the amp or amps that are chosen. but with all that out of the way! Dimensions I have to go with are 48" tall 51" wide and up to 97" deep but I really dont need that deep lol! we still need to leave room for amps and batteries! I was throwing around the idea of a clamshell or maybe a 4th order just not …

Pretty simple question. Anyone ever personally built and owned two 15s in a seales enclosure? Im gonna be doin It soon probably and was wondering what your results were. My box design Is around 5 cubes after displacements. They'll be two old style havoc 15s. And ill be running them on mg aq1200 until budget gets me a bigger amp or a diff box or set up. Thanks

if anyone knows were or who makes 8 inch aero ports please text me 606-875-9811 thanks

I currently have 4 cube after all displacement with 43.75 sq/in of port fireimg down the middle tune @35hz. I was told that offsetting a port to any Side would raise enclosure efficiecy And get louder.how true is this? my new plan is 3.8 cube with 50sq/in of port tune @32hz with the port off set. sub are fi btl12 n2 with the mmats hd4000.05 and dc xp 270 alt x3100 in the rear xs2700 up front in a 03 impreza sealed off from the trunck.

Does anybody know who i can talk to about getting a 6th order bandpass design. Thanks!

Topic says is.. I'm still running a Fi ssd 15 and a Sundown sae-1200d.. I know I'm not giving a lot of detail here, but should this setup hit the lows like in the song " White Girl " ? If so do I need a new box tuned to a lower hz?

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 had a place build me a box and i gave them website to check out the specs, i just wanna make sure everything was done properly before i go ahead and accept this box. fits perfectly in my trunk (he measured before he made it) my subs are still being manufactured... so i have time to correct this if not. any pro response would be appriciated. H 14" x W 32" x D 24" is the overall outside dimensions. im not sure what he tuned the port to. the outside of the port is 12.5"x3" if you need more measurements id be more than happy.

I'm thinking about doing something that I've only see Steve Meade do, on a much larger scale. I want to build a small setup to just listen to music in the garage with. I have a cheap set of Pyle component speakers that I can use.. I'd like to build a ported enclosure like this. They would be ran off of a really old 100 watt 2 channel Pyramid amplifier. I do not plan on adding a subwoofer to the setup, just this set of components. Since this old amp doesn't have any sort of SSF, HPF, or LPF, it's playing a full range. I will have a crossover for the tweeter, but the woofer will be seeing even subsonic frequencies. I'm thinking about using 1" PVC for a port tuned around 40h…

well i am starting the build for 1 zcon 15 tomorrow and i have a few final questions id like to get out the way to make sure this is done right the first time..... 1: should i put 45degree angles in all the corners for better airflow??? here is the link to all the dimensions and everything im doing (thanks Alton!!) Post #11 this is my daily set-up so im not going all out for spl.... i had another question but i cant think of it at the moment... haha im sure ill think of it here shortly so ill post as soon as i do haha thanks guys!!

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

Wanting to do my next box with birch, what exactly am I going to need to look for when buying it. Thanks

I'm thinking about getting a professional shop to design and install a setup of 2 10" Icon's for me. Reason being is that it's going into a trunk (not a show car) and I want it to be practical (able to put THINGS in the trunk again) rather than having a simple carpeted box ... I want it to look good! I'm thinking about firing in (seats can fold down), sealed off, all carpet ... They talked about covering the amplifiers ... covering my battery in the trunk ... But if I'm paying a shop, what are some options that I should inquire about? Removable plates ... Plexiglass ... Company Logos on the inside deck lid ... stealth on both sides of the trunk ... lighting ... I don't w…

This is what I have right now Most of these number where pulled from another Tahoe build to give me a base. Ok now I just messed around with the port length until I got the tuning I wanted (33-35). I don't really get how it is longer than the box? This my first box design and is a temp. box for me to use about a month or so. Sub will be powered by a Cresendo 2k at .5 or 2ohm depending on voltage gain All the way down, and I'm going to take it easy. Any input will be greatly appreciated.

I need advice on where to face my subs. my current box only fits one way. facing back, it is in a 1996 geo metro and was wondering us anyone had experience with subs back in the hatch. Thank you very much

Hey guys It's time for a new box and while I was looking around I came across PWK Designs. Has anyone dealt with this guy yet? Looking at his youtube videos and his official site it looks like he takes everything into account. If anyone has had a box designed by him let me know what you thought about his services and was it worth it?

im making a box for 2 kenwood 12s. so far im kinda lost on how to make it but this is my design. 25x25x40 that will give me 3.5 cuft thats inner dimensions. i was thinking i put the port inside? the port would be 25x3 and it needs to be about 45 inches to make it 33hz. what dou you guys think? am i off to a good start? bad start? and input would be greatly accepted.

Alright so I'm making a box for 2 kenwood 12s. I'm thinking 1.5 for each sub. Idk wether to do a single chamber for both or separate chambers?.. I'm leaning more towards one chamber and one port. I want it tuned to 32 hz. This box is going into a trunk so size isn't a big issue. If anyone could make me a nice design I'd be very greatfull. Thank you.

I was wondering if anyone has done builds on a 97-00 Honda crv and how much space I should leave between the box and hatch?
