With that being said I would keep the brutus amp seing as it will sound the same.

The box will be the deciding factor. Steve Cook does very well in the meca sound quality league with 2 death penalty 18s in his avalanche. Just my two cents.

That looks to be a 4th order bandpass that is accidentally tuned crazy low. Great vids!

I was wondering will the memphis mojo 4kw run at a 1/2 ohm on burps with proper voltage. I do know that the 08 version will run at 1/2 ohm but they changed a few things on the new mojo.

The Car Stereo Shop will be holding a 2 day usaci single point show on August 21 and 22. We are going to be having our Annual Midnight Madness sale also during these days!! Its going to be a great time so come and check it out. Give us a shout if you think you might be coming. Our number is 1-334-887-8422

My advise is to find someone with a meter if u dont have one and test, test, test. Get a bunch of mdf and go crazy. You would be suprised what werid designs could work for you. What kind of vehicle are you trying to compete in?

That was what I thought too initialy but the second box i tried was about 6 cubic feet and had three 6 inch areo ports and only did a 138 dbs in the floor using the term lab meter. The next box was about 5 cubes and had two 6 inch areo ports in it and I got a 143.6 dbs. The box i have now is only about 3 cubes and only has two 4 inch areos and has me in the mid 147 db range on the same meter. What Ive been told is that if you have alot of port and airspace, you better have some powah. Honestly I dont have much of that at this moment. For me its been the smaller the box the better the spl.

2000 grand prix 4 door.

I tried a different enclosure with woofers firing out and port firing back and with my seat unbolted and out of the vehicle I managed to do 147.2 @ 68hz and 146.2 @ 68hz with seat down and in vehicle. I gained about 3 db by changing enclosures and raising 24hz in tone. All measuments done on term lab. Im extremely happy with the score but always tring to improve with my current equipment. What should be my next move to gain a few more decibles and still stay within usaci rules. Any sugestions on box tuning or equipment would be greatly appreciated.

Im on my third box with the subs up port back. When I get my enclosure near perfect then I will resin the inside. Im thinking about sealing the trunk from the cabin and running the subs foward but Im afraid that not having a loading area might hurt spl.

Do you guys have any sugestions on woofers or amps? I am going to compete in usaci trunk 0-1000 the rest of this season and I plan to compete next season in 0-1000 using a memphis 4kw if my cash is right.

The reason I want to put them in a fart box is because the 12 w6s is what i have right at the moment. My plans are to run L7s or CVXs. My objective is to get as loud as possible using what I have at the moment.

Does anyone know anything about designing a bandpass box. I have a pair of 12 w6s in a ported box w 2 6 inch areo ports tuned to 44 hz and a jl 1000/1. I can do 143.4 db at a 48-50 hz tone. Im trying to get in the uper 140s without reaching the 2500-4000 watt amplifier range. Any help on design principals or general advise on how to get louder would be greatly appreciated.

If you do decide to run the bass eq on then I recomend running q at 1.1 and center frequency anywhere between 40 and 50 hertz. Alot of fun to play with on the 1000/1v2.
