After reading a lot on the forum about the bass (or lack thereof) and the difficulty finding speakers I decided to take a stab at it and do an experiment. I decided instead of using it as a sub I would convert it to a mid-bass unit and add an additional sub for the lower frequency stuff. It turned out, for me, to be a worthy project. I searched on Crutchfield and found a pair of Kicker 4" full range speakers that are for marine environments. I have attached the link for them:
Kicker KM42CW
These are 2ohm speakers which are the same as the subs currently installed and have a relatively decent 89db/1 watt sensitivity and frequency response (60-20k). They run $120/pair
Although these are 2 way speakers I took the plunge on modifying them for what I wanted. I clipped off the tweeters and the wiring feeding it, creating a 1 way speaker.
After yanking the sub enclosure I removed the factory speakers and test fitted. They fit perfectly. The only modifications I had to make was to clip off the little alignment button molded into the enclosure which correctly places the original speaker (sorry, forgot to snap the pic but its pretty obvious when you test fit the speaker) and shave down the new speaker terminals so they would fit in the factory female terminals. After hooking the wiring up and placing the speakers in the holes I used the supplied stainless steel screws to affix them.
Everything mounted back up:
DynaMat - a jaw dropping difference. I put a 12"x14" piece on the body panel behind the enclose too. In addition to this I replaced all the door speakers with JL Audio speakers and did the doors with DynaMat as well. The only thing I hear is the engine and a light amount of wind noise around the windshield. Simply amazing stuff.
I have an Alpine ilx-207 head unit. I went into the setup and turned the subwoofer on to cut out the low frequencies and tested without the new sub installed to see how it sounded and was impressed with the punch. Buttoned everything up and voila - satisfaction.
