Finally decided to upgrade to an Eclipse Nav Stereo. I also bought the following:
Has anyone had any problems installing aftermarket with the Shaker amplifiers. The instructions for this harness has a comment to not use with OEM amps.

 

You'll have a turn-on "pop" unless you wire in a voltage regulator. Search this forum and you'll find where I put up a diagram showing how to wire one, or I think TacoBill showed in one of his excellent install threads. They're like $3 and go on the remote wire(s) (blue wires on the smaller harness).

 

Well, I finally took the time to install my Eclipse 6620 with bluetooth kit. The hardest part was removing the center console. I can't believe the sound coming out of the stock speakers ....amazing. Eclipse did a great job with processing options for sound. I honestly thought the Shaker sounded good, but it did lack control over the mid range and other frequencies. Very pleased with the 6620. Thanks to "Infinity" for bringing up the voltage regulator mod....worked like a champ.

 

 

Can you post some pics of the finished product?

Thanks
