heres a few pics of my trunk. i have 1 12 inch 1200 watt spl sub, an 800 w amp and the box is what i like the best. because of the design, the air is sucked into the port, instead of out of the port. if you put a dollar bill in front of the port, when the bass hits it sucks the air in-- i think the bass is alot ceaner and better cuz of it. when i first got the box it wouldnt fit under the lip where the rear deck is. but it was a prefect fit in the dip in front of the wheel well if you take the liner out. i cut the back and the floor liner to the shape of my box- now it slides all the way back to the crss bars for the back seat which saves me alot more room and if anyone broke into my trunk to get it, they would spend about a half anhour trying to pull it out!! i do have a factory h/u so the box above my amp is a line level converter that is wired to my 6x9's and i have a universal external bass control running thru my rca's so i can adjust my bass from the drivers seat. its not alot, but perfect for my taste...

i paid 400 for everything brand new from a local install shop that used to work at. u can get the sub off the net and the amp for less than what i paid i would guess, but i havent ever seen the box anywhere but here. i really like the way it fits in the trunk- i even have a full size spare! the amp model number is performance technique ibcm 772 its 2 channel. the sub i am not sure of but it is the silver voice coil cover and is rated at 1200 watts max- dvc.

The different port design has nothing to do with the better sound quality...The air goes both ways because when the cone moves in, the port sucks air in and when the cone moves out it blows air out.....If you really want good SQ you should look into sealed boxes or low tuned ported boxes...Is that a prefabricated box? Because if it is, it's probably tuned pretty high...If you get a ported box tuned lower or a sealed box your response should be much better....Generally prefabricated bandpass boxes aren't really good...But if you're happy that's all that matters...

well if it works i guess its fine, but you should clean it up more like place the amp somewhere other than attached to the sub box for a cleaner look. you probably aren't going to show your car at any shows but thats how i am. i like everything clean.

I just want to tell you that I have only seen bad things with Performance Teknique. I have a few local shops around me, and the guys who dont have the well known reputation promote PT and the ones who show up in car magazines, wont mess with that amp.

Im sure u have a warranty on it though, in case anything bad happens.

update-- i had that PT amp in my car for almost a year and it hit everyday-- never overheated all the way from texas to Indy- 16 hr drive! I sold it with the sub and box and the guy is still ahppy with it. I have a new setup with a MTX 9500 12 inch sub, a MA audio 1000w RMS amp, MAmphis 1 Farad cap, all custom installed. I have the Kenwood double din touchscreen dvd player and I am still looking for a good deal on some infinity interior speakers. The sound is quite impressive, but i can see my rear deck raise when the bass hits-- SHOULD I PORT IT??? I wanna talk to someone that has ported their rear deck.... anyone out there?

I have thought about it, but found out it takes money to do that and if you want an easier solution, port through the rear armrest.

Do you mean a direct port from the box or just an opening in the rear deck not attached to the box? That is one thing that is important to know.

just an opening in the rear deck not attached to the box. I cant do the armrest thing cuz my setup blocks the whole rear liner with the box, so very ltittl air would get there anyways. I am comfortable with cutting into the deck, I just wanna know the dimensions and if its worth it....

FYI:You wont get louder porting through the deck or firing through the armrest...

I heard that it's NOT a good idea to mount an amp to a speaker box, the vibration from the box is transfer to the amp, which will cause the amp's life to die faster. I guess components in the amp can get loose with all the rattling.

VERY true... vibration is an amazing force, and can knock some of those little solders inside that amp loose. I had a buick with 2 15" subs that vibrated the rear brake light sockets out of the lens... Just goes to show. I have 3 12"s in my legend, and I'm upgrading to all new subs, and going with 4 of them, I'll post pics when all's said and done (shouldn't be too long)

i have used performance technique before, and i thought they were very good amps for the money. a couple friends bought their 600W amp for under 100 bucks, and never had a problem w/ it, (i don't think?)

anyways that box design is pretty cool, but i would think it would work the same as any other bandpass box, but the ported part being in the front of the box?
but i am always impressed how bandpass boxes hit, they can make just about any sub sound decent, and very loud, w/ little power.

do you know, if the box was specifically made for the sub, or is it a prefab?

i do really like the custom work to the trunk to get the prefab box to fit good tho
