Oil change
If you change your oil and filter religously at 3000 miles, than conventional oil would be adequate (decent brand) and save yourself the cost differntial from synthetics. Most who use synthetics are trying to get longer oil change intervals (5000+) or high mileage/heavier load use.
I am looking at Pioneer models...AVH P3400BH. Pioneer has a number of models in this line from basic to fully loaded. The 3400 is middle imo, I don't need a lot of bling/etc. Price is running $300+ online. Let us know what u get and install pics if you can.
Thks for the input. Took your suggestions and talked it over with a local car stereo dealer I have dealt with in the past. Recommends I replace amp with 5 ch amp, component speaker set (front/rear with tweeters and crossovers incl), new sub. Looks promising but again need to make sure one amp...
Crutchfield has the gear and tech assist to work thru the upgrade. Probably should replace hu and amp same time. It can be made to work only hu but cumbersome, crutchfield tech assist details challenges.
Just bought a 2005 4R Sport Edition and am seriously disappointed in quality and volume of the JBL system. HU is adequate for now but volume is low on cd's, barely adequate on radio. Feel initial upgrade needs to upgrade amp and at least front/rear door speakers/sub (phase 1).
Prefer two...
