Same with me. I try not to answer unless I have some input on the subject that will help in some way (doesn't always work though).
Looking at your profile, there's only one topic that you started that no one answered and as Purple04 said it was pretty technical about stereo. I guess no one had an answer to that one.
Now as far as you buying a 4 cyl instead of a V8, The PT doesn't do that well on gas mileage...I get better mileage out of my Vette but I still use the PT as a daily driver.
