I'm looking to get more center imaging in my FB ('84 GS). Right now, I'm thinking about either replacing my storage bin in the lower slot of my stereo mount, or behind the middle of the upper A/C and Heat vents. Has anybody done this, or has any other suggestions? Thanks guys!

 

I'm going to assume that you have predominately factory reciever/speakers. The best way to enhance imaging in any car is to change the position of the factory speakers. Unfortunately there's no room in the RX. you may want to try front channel speakers with aimable tweeters. Also put bass blockers on them. 250 Hz should work fine. Remember, imaging also means that the bass comes from the back, treble comes from the front. If you are hard pressed to have a center channel, Alpine and Kenwood make designated center channel speakers. Both manufacturers include a designated power amplifier with the speakers. They're available at www.crutchfield.com ... Happy hunting!
