alright, just got a new car (96 accord LX coupe), and I am putting most of what I already got as far as equipment goes into it, but need a new sub.

right now I have my DEH-P600UB in my rocky with the rear channels of my 475a powering a really cheap audiobahn (AW1051 I think) that I found from a long time ago in a sealed box thats around 2 ft^3. its wired to 8 ohms so there is only about 90 watts going to the sub now, and its not crazy or anything but it is (was) a decent amount of bass for what it was. anyways I started hearing it make a horrible sound at higher volumes, the surround is actually torn about 1/5 the way around now.

I am planning on using the same amp but getting a single 4 ohm 12" DCON. the amp should be able to deliver around 180 watts. I am going to fiberglass in the spare tire well and make an enclosure that will probably be about 1.25-1.5 ft^3 and make a elevated false floor to hide it.

now I am hoping to have at least as much bass as I did if not more, but Im not sure what to expect.

the sub is better, and it will be seeing more power, BUT the rocky is a pretty small vehicle and the sub is pretty much right behind me, and in the accord it will be in the trunk, upfiring underneath a false floor (but I am going to drill a crapload of 3/16 holes in a 14" diameter area above the sub before I carpet the false floor)

so although I know nobody can give me a definite answer, would you guess it will be more impressive, or less impressive than the smaller, crappier sub that was in a smaller cabin right behind me? and we are strictly talking about output, I KNOW the DCON will be cleaner, its a better sub and its back in the trunk.

Sounds like you'll be right around the optimal sealed enclosure. And if it's a little quiet. You can always upgrade your amp and double the power to around 400 watts.

You can grab some polyfill or acoustastuff, it helps slow the air movement inside an enclosure and tricks the driver to act as if it is in a larger box. Dcon does not need gobs of power to play well.

alright, cool. I hope to start the box soon, just dont quite have the money yet to buy the sub, and Ill be out of town all of april, so if I dont get the project done before then, I wont be working on it until may, but Ill be coming back with plenty of money to buy the sub and any materials I will still need. now Im thinking of selling the infinity amp and buying a little bit more powerful 4 channel amp, and still running fronts and sub off it. might just have to buy a decent mono amp and a nice 2 channel and sell the 4 channel to pay for some of it...
