Personally I just got the P6000UB myself. With s1795so2's help I was able to hook it into my Bose amp via the remote cable off the Pioneer headunit into the Bose plug and walla! It had a really good sound with the factory Bose speakers, but Steve gave me a great deal on some new Memphis 6.5" front speakers and some kick ass Infinity Reference 6x9s for the rear and BAM!!! Talk about a difference!!!
I just got the Infinities installed yesterday and my god the bass is amazing. I was able to modifiy the Boses brackets that held the old factory Bose speakers to mate perfectly with the Infinities. And the bass from them is amazing!
Now I just need to get my Subzero case and 12" Rockford Fosegate Punch with the Hiphonics amp and I will be set!!!
Personally you can't wrong with any high end Pioneer head unit!!! And got mine at Best Buy as well for $249 bucks as well.
And with my unit I dont carry any CDs in my car now. I just have two 4gb USB thumb drives that carry all my music and the 6000 just rips through the USB drive like there is no tomorrow!!
I just wanted to thank Steven, aka s1795so2 on the boards, for ALL his help in making this happen!! If it wasnt for him, I would have never gotten my headunit to mate with my factory Bose amp.
I just need to finish the project by getting one of the Humont Grand Prix brackets with the Blue LED background to really set it off And I will post pics once that is completed!
