I am so glad to help. Its a nice setup. I cannot overemphasize enough the difference the 6x9's made in the back. Monday night I did some spirited (to put it lightly) driving with the top down and the bass stays in the car and sounds amazing. Bruce Springsteen's "Human Touch" sounds unreal.
One more thing, The W505 is coming out in April. I already bought the 1st one due in, so I'll be sure to let you all know how that works out.
Thanks, Joe D.
*****UPDATE*****
The Alpine IVA- W505 head unit was installed yesterday. I've had a month or so to live with the existing sound system and I decided that while the car was in, I'd have the system revamped a bit. The additions/replacements were as follows;
IVA 505 replaced the IVA 205.
The 4x150 Alpine power amp replaced the 2x150
I added the imprint processor
I added the Bill Jeuhle subwoofer enclosure with an 8" JL Audio sub.
All work was done as professionally as possible by Anthony @ Zippo's car stereo in South Plainfield NJ.
First let me say, the W505 is light years better then the W205. The Ipod controls are unbelievable. I believe the installer ran the USB connection to the Ipod. The ipod control is so smooth, it almost feels like its not a separate unit. It feels like its part of the 505. The Album art displays on the screen nicely. The touch screen is better than the 205's in the sense that it reacts quicker and more positively to the touch. The bluetooth connects to my phone without a glitch and using it is a real treat. Moving from screen to screen is flawless. The whole system has a much more "professional" feel to it. The installer tuned the system with the imprint unit. The processor has made the stereo sound as if its not installed in the inside of a little Porsche anymore. The soundstage is big and the music is well centered, fuller and even more accurate than before. Its unbelieveable. Alpine has listened to the consumer and put together a top-notch system. It even has 4 different screen colors to match the interior of most cars. (Amber, Magenta, Blue and Green).
The subwoofer enclosure is JUST what the car needed. The molded plastic box comes barebones from Bill Juehle (billjehle.com). My installer carpeted the outside and sprayed the grill black. He fitted the box into the front passenger footwell and bolted it down. He installed a JLAudio 8" sub. It sounds WAY bigger than any 8" I've ever heard. Probably because the interior is so small. Trust me, you dont need any more than this 8" in the Porsche. The car now has bottom end in the sound. The fullness is incredible. The accuracy of the sound is great. No distortion, buzzing or false artifacts in the sound. Just clean fullness, with crisp highs and pounding (yes, Pounding) lows.
In order to power the sub, my Installer had to change the 2x150 amp to the Alpine 4x150. What a difference that made. The clarity and power are amazing. The gain is only at the halfway point. My installer recommended this because he felt it would provide the cleanest power obtainable, while running very cool in the process.
A word about the installer. If you live close to South Plainfield New Jersey, Zippo's is the only choice for professional sales/service and installation. Anthony who is the manager will take care of you. He really cares about what you want and he will set himself on fire getting it done for you. Trust me, I am just a customer and have NO stake in this whatsoever. Anthony is TOP-NOTCH. He knows Porsches and he will do a good job for you.
All I can say is, this is the best sound system I've ever heard in the best car I've ever driven. I am as happy as can be. I hope that my experiences help anyone else interested.
