I ordered the System 450q for the Tundra Cremax Platinum with JBL premium from OEM Audio +. Pre made wiring harness, 4 tweeters, 2 passive bass blockers for front door speakers set up to plug in directly into the factory wiring harness at the speakers, sub with Rockford Fosgate amp, remote bass control, and the necessary brackets, zip ties, wire guard, battery fuse connection etc. I am happy with how the system sounds. I guess if I were to sum it up I would say that it now sounds like the system I hoped that Toyota's top trim level truck would have had in it. Listening via the USB input, Sat input, and local radio presents much clearer music with nice imaging at the loudest volume settings. No more booming muddy washed out bass coming from the front door speakers. The new sub performs nice with all music I listened to. Heavy bass music had the sub struggling a bit at higher volumes but that's not what I listen to so not an issue for me. Bluetooth connected phone initially didn't sound as nice until I realized that I had the eq on my phone set away from flat. Once I set it to flat on my phone the sound was much better, particularly the bass. The install was pretty straight forwards. Daniel was cool and texted back and forth with me after biz hours to answer questions that I had. The instructions that came with the system could have been a bit more clear with better pictures and a video specific to this system install video would be nice as well.
