JBL p1222 & Diamond amp INSTALLED (w/ pics)
All said and done, I built three different boxes and some wasted effort, but the end sound result is not only clean and heavy when you want it to be, but pleasing to my eye.
I used a JBL P1222 & Diamond D3 600.1 amp... and of course the wiring harness from Technic. (Thanks again! Highest quality product.) Here's the finished pictures as to not keep you waiting before I ramble... I don't have a ski pass-thru or fold down seats, so I removed the plastic piece behind the fold-down armrest to see about cutting through. I had already tried a rear facing box that didn't produce the sound I wanted. It was definately strong enough to immediately break my gas lid spring thing, but not much was getting through to the cab. I had hoped making a pass through the rear deck would help enough, but it didn't. It did, however, turn out kind of nice. Pointless, but nice. ...IDK, maybe it helps. I decided on a forward facing design through a hole I would cut in the seat backing behind the plastic piece I mentioned earlier. And here's what I did to make it presentable: Also to mention, I made the floor everythig is sitting on so I wouldn't have to cut a hole in the original trunk. Here it is before the box was installed:

Looks good! You should really look into amplifying the rest of the system. Makes a world of difference.

Do you have any pictures of when you cut through the back seat? I have been contemplating this as it seems like the best option to let sound through the trunk. What level of difficulty do you think the process is, have you ever thought of creating a DIY for this?

I like how it's next to the baby seat.

unfortunately no, I don't have any pictures of that part. It's ugly as hell though with out the plastic trim in. It wasn't hard to do. I used a razor to cut & peel the carpet off the back and then used a drimmel w/ a saw blade to cut through the plastic. It made a huge dusty mess. Cutting through the plastic trim piece in a straight line was interesting. The speaker grill was ordered to fit from Reliable Hardware, and the rubbery trim is that door egde guard stuff from an auto parts store.

Looks damn nice. I'd like to do something similar. How did you get the amp to fit in there? Pull the liner or what? The lid won't close on my amp even when I remove the liner. Did you have to trim the trunk floor?

Thanks, I appreciate that. I took out the original floor of the trunk and remade it out of plywood. I cut the hole in the wood, added the plexi, and cut a whole in it that the amp fits through. I did take out the liner and cut a piece of wood to fit in there for the amp to secure to.

just for fun...
...I hate measuring and making sure everying is square, so I printed all the pieces with a large plotter and traced around them onto the wood.

Looks great, would you be willing to post the dimensions of the box. Perhaps the dimensions of each piece of wood? I am considering a similar design for a 12" Type-R, but a sealed version.....

I'll give you the model and you can measure it. If you don't have AutoCAD, there is a free viewer called Autodesk Truview that you can download here: http://usa.autodesk.com/adsk/servlet...112&id=9078813 ok... the drawing file will have to wait until I get to work. .dwg won't upload and I only have winrar here to pack it, not winzip. I'll get it posted in a bit.

Uh, you traced a pattern onto a piece of wood? That's how you made sure it was square? This isn't a gender-based comment, but this isn't sewing a dress you're talking about. Measuring and making things square is really important. If things aren't the right size, and square, not only will you get leaks, you will also lose acoustic energy as panels vibrate in ways they shouldn't, because the enclosure doesn't fit the way it should, and you lose output and sometimes hear noises that you shouldn't. I strongly recommend to anyone making an enclosure to use measuring tools and a carpenter's square. The technology is cheap, older than dirt, and not hard to use. |

No, that's how I got the dress pattern onto the wood. Of course I used a square to double-check. Everything you said is all fine and good, and I appreciate it, but everything is exactly the right size, square, fits perfectly, absolutely no leaks, and sounds very clean and heavy.
