About a year ago I put in a sub inspired by the "big bass little space" family of threads. I've alway been a fan large subwoofers: there's no replacement for displacement. The budget was tight as I was still in school, so I got a 12" boss blade extreme for something like $50 from amazon and a pioneer amp off craigslist. It was very loud but sounded bad.
About this time I had started reading up on infinate baffle subwoofers, which provide high quality and good response to very low frequencies, abit at lower efficiency. Sounded good to me, so I got out the sawzall and cut a hole in the inner fender below the floor to turn the sealed box into an IB setup.
It sounded great. Not as loud but much more musical. But I wanted more volume so I decided to upgrade. Fi car audio just came out with a couple of drivers built just for IB: a 15" and an 18. I went with the 15. Both are an excelent value, the 15" was only $120 shipped. It displaces about 3.5liters, which is about 5 times as the 12" boss. It's a much better driver.
It took some clearancing to make the big driver fit. It's deaper so I spaced it out with 1.5" MDF. The wheel well was in the was just a little bit so I made room with a hand sledge. It's a tight fit but I got it in. This was my first time sticking carpet down, and it ain't perfect but it's a lot better than nothing.
Here's a shot w/ my helper:
And the whole back of the jeep:
I had the amp under the rear seat before but it got hot so I stuck it on the back of the seat. Should be easy enough to hide when necessary.
It sounds great. I haven't cranked it all the way yet as I want to let the glue and foam fully cure first, but it is louder and sounds better. Looks better too.
I've ordered a grill to protect the speaker. And I'm going to upgrade the speaker power wire. When I first put it in I just used small wire that I had laying around but the amp would clip more easily that I expected and I think low voltage had something to do with it.
