I got that Sony H/U I wanted on the weekend.
It sounds quite nice already, and I am still tweaking the sound. At very high SPLs that mask all outside sound; including nearby Nuclear Explosions, the CDs sound clear and clean.
Hey, the Cymbals are back! The stock speakers (for as long as they last) sound much crisper than before with an extra half octave or more of high end. They even provide a clarity that I never expected when I had the factory deck installed.
Next step, I am replacing the internal factory speakers and then for X-mas, I'll add a single 10 or 12 inch with 100 or 200 watts in the back. I am after clean, even sound and not booming, weld-breaking bass!
Remember, I picked this Sony because I was tired of being a slave to the detachable face plate... :nana
