|Removed 6x9's and 3.5's, then replaced with the Type-R's with tweeters now in door sail panel|
I first began my research for a HU that had a 24-bit DAC connection for my iPod that I could connect and hide in the glove box. However, the ability to realistically control 100GB worth of music while driving was a MUST. I couldn't have asked for anything better when I found Alpines iDA-X305S Digital Media Receiver! With the over-sized wheel in the middle that becomes the iPod click-wheel, the ABC search function, and bright display makes any amount of music manageable. Another plus in my opinion is the lack of a CD player which gives the HU and more solid/clean install.
Always satisfied with Alpine, I added the new Type-R components up front with the tweeter relocated from the dash to sail panel and Type-R 2-ways in the rear. All of this, of course while applying Dynamat to every panel I could get to.
Wanting more from the low end, I installed 2 JL 10's but trying to save space I found the Alpine PDX-5 which gave 75w to the doors and 300W to my 10's....perfect. With all 1/0 gauge premium wire used for Big 3, each channel is getting more than enough power from an amp the size of a phone book (needless to say this amp is that awesome even without the Big 3).
With the large array of music choices I had at my finger tips now, I added a level control under the HU to control the JL's. I am now riding in Alpine euphoria due in large part to my newest addition, the IMPRINT digital sound processor. The only feedback I get from others is...."WOW", which says it all. This little addition has taken my audio to a level no other addition could possibly do.
Why did you decide to upgrade your A/V system?
I went to a military college and music allowed me to get away. So naturally, it became my life/passion and honestly I just love rockin' out!
What's the first thing you show people about your installation?
You mean after they ask what size and how many subwoofers I have? :) I just open the glove box and show them the tiny IMPRINT box and tell them it's the true workhorse.

Why did you choose these products?
I chose Alpine because I love the quality and innovation. I know there are in fact far greater SQ speakers, but w/o going PRO you can't beat the new Type-R's clarity. (Personally)
What was the most difficult part of the installation?
|Custom dual 10" sub box made for Wranglers, but fits like a glove in WK's|
I would have to say when I decided to add subwoofers to the SQ. My Grand Cherokee has very little cargo room as it is, so a large box and multiple amps were out of the question. I reeeeally got look when I found that the box made custom for Wrangers actually fit snug against my angled back seats and still allowed a reasonable amount of cargo room.

What plans, if any, do you have for future upgrades?
The only thing I will be changing anymore with the Jeep is new IMPRINT test positions. I've kept a log of each one and still seeing if I can find that "one" setup.
