SPL & SQ / Fabrication

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?

As the topic says I am looking for any and all tips to improve my SPL. After some REAL quick testing that I'm not to sure was accurate. I was told I was doing a 143.5 Legal @ 32Hz. I believe the 32Hz part, but I'm not to sure about the numbers. So any tips, tricks, or ideas you have. Throw them my way. oh and BTW I know I need more power. I'm working on that detail:

In my 2003 tacoma single cab and bench seats doubtful i can get two tens ported. Car audio dealer told me it wouldnt sound good with ports on side of box. So am think of one ten ported or two sealed

I haven't had much experience with the science behind port tuning/building, but I've been doing a little research and some calculations and have a question concerning port "size". Let's say I have a 1 cu.ft box, and I want to put a aero port in it with a tuning of about 33hz. I used a calculator and I came up with a 2" diameter port with a length of 6.3 inches.. or a 3" port with a length of 15+ inches.. My question is, what's the difference in having the 2" short port as opposed to the 3" long port and achieving the same tuning? To me it would just seem logical to go with the small and short port to save space and material, and just be an overall convenience.. but this i…

I currently drive a 2006 galant and i have been having trouble with getting upper bass( about 50hz and up) out of any setups i have ran.

(2) infinity reference 12's -kenwood 9103d @ about 500 R.M.S. - 1.25 Sealed each before sub displacement - rear firing 2.

Hi all,has anyone built these ports and where can i get the formula to calculate the area and cutting angles please

I've never built a box before so here go. Starting the build tomorrow, are there any changes I need to make?

I have an RE Audio SX 18. I've heard rumors that this sub can do 2,000 watts RMS fairly easily in the right box. I currently have about 500 watts going to this sub in a 10ft^3 box tuned at around 30 Hz. It's pretty loud. I got pulled over a few days ago for having my music too loud and the officer said "Dude, you were shaking my car, what do you have back there?" Got off without a ticket . I wanted to step it up a notch so I just ordered a Hifonics Brutus BRZ1700.1D. Which does 1700 RMS @ 1 ohm. I designed a box with a net volume of 7.19ft^3 tuned to exactly 34 Hz. Sub up, port back. (My old box was sub back, port back.) For the record, this is going in a 2006 Expedition.…

I'm looking for two tens to put under my back seat, can anyone give me suggestions on subs and who makes a good box for my 2010 silverado. I would like good SQ.

Tuned to 32hz.

I need helping figuring out how to go about getting 6.5s in the doors of my 86 GMC Sonoma. As some of you might know that S Series trucks (S15s and S10s) around that year didn't come with door speakers from the factory, only dash and back panels. I never fiberglassed before so if possible i would like to stay away from that.. but if i must i will take on the challenge, if i could get away with just putting a sheet of MDF on the door and cut holes for my 6.5s that would be great.. but i don't think there is enough space between the door and where the MDF would sit because there was no speaker in before hand so GMC didn't give it the room for speakers so somehow i have to m…

I would Love to hear from a few people that have used Luxury liner pro. I have 4 sheets of LLP. I bought the LLP with the plans of installing on the front floors and under the front door panels. If I have any left I plan on the front of the rear wheel wells. The box will be forward firing with the trunck sealed off. I have already dampenered the inside of the car. My goals are to lower the highway road noise and just to lower the noise floor of the car. I realize every application is differant but would like to hear what results and experiences some people have had with the LLP. I have used the search function with no luck and also went to the SS forum but them guys a…

Anyone know where I can look at pics of pods? I'm having some started today for my jeep. I'm not building them myself. Is there anything I need to be aware of or tell the person making them? I don't know jack about them. I'm installing my Kicker RS6.5 component set in there. I'll probably mount the tweeter in the co-ax. Any comments, opinions? Me competiting in db drag street class means I can't have anything large or alot of glass on my door.

For the Crown Vic.Town Car 4.6 Now the Exp.Navi 5.4 Im a bit confused on what they did exactly. maybe someone can explain it better. says its from an 08 navi, but alot the bolts should be the same.

OK, So I recently aquired a 1996 jeep grand cherokee and am in the planning phase of the project. I am looking at running a 3:1 ratio 4th order with either 4 15" or 18" drivers. The issue I am running into is that I am concerned that the box height will end up too low to mount the drivers on a flat baffle. With this being said I was wondering if anyone has toyed around with angled baffles. With this setup I was going to do a driver's side port and tune around 45-50hz. Would this be too much of a hassle and prove to be a nightmare, or should I try to use a more upward firing baffle to fit the 4 drivers (similar to watt's truck but larger and drivers stacked in a 2x2 …

Hello. I've got a BTL 12, the new model, with the spl gap, short coil and cooling and I'm looking for some ideas on a box volume I can use for burps and keep it mechanically safe. I had an old 1.3cf box laying around so I used that for some quick testing. The highest score with all testing was only 147dB on 3600w clamped watts. The actual power to the woofer will be a bit over 4000w once I get good battery. The goal is to score 150dB out of this single 12 and the small box is 3dB short. This is how the 1.3cf box looked at the end of the testing: I also tried all combinations of sub / port facing except both of them back. A max volume suggestion would be useful as I …

So I keep getting told that an active front stage can be and usually is better than a passive component setup. Now, doing the front stage is very new to me. I've really only done a co-axial set powered by a 2 channel amp. I'm going to need some help with speaker selection and ways/tricks to make sure everything is installed/tuned correctly. To put a number on a budget, I would say $400. That number is just what I have set aside for the front stage currently. Sound deadening is not included with that budget. This is going into a 2014 Fusion. I don't want to cut any holes in panels and I can't fiberglass so stock locations will be used. Which is a 6.5 and tweeter. I will b…
