Ok so I'm calling it quits for now, time for dinner but I decided to start tonight and made some progress. I got both of my tweeters mounted in the A-pillars. Wires run, not connected to x-overs yet.
I also got the door woofer installed on the drivers side. I had to run out and get some foam weatherstrip because the JLs are just a tad smaller than the stock speakers or else I'd probably have both speakers in at least.
So what I have right now is no tweeters, 1 JL, 1 Sony. It actually worked out well because I was able to compare the two at the same time. I made 3 important and definitive observations:
The upper mid range to high frequency sound is not as loud from the JL 5 x 7 as the stock Sony - However it's quite alarming how high of a frequency is coming from the Sony "mid bass woofer". sounds i thought were coming from the tweeters are actually coming from the door speakers. with that in mind...
The stock tweeters are basically useless. Without any tweeters at all it really didn't sound all that different. I am hoping the JL tweeters will bring the system to life.
The "punchy" and lower mid range frequency sounds worlds better with the JL's. where the Sony's sound like they mute out when the bass hits or just sound straight up distorted, I did not note any distortion on the JL side and the bass was very crisp.
Don't call it until it's all done, but I think at the very least this setup will remedy the sloppy sounding mids and non-existent high's the stock system delivers.
*edit* This was all at high volume mind you. the Sony system is fine at low volumes but really let me down at high volume. don't go on a witch hunt thinking the stock system is total crap, i'm sure it's fine for some people.
