Just finding this RTA has got me interested again too. I started looking around to see what is out there both old and new.

I thought that because of the integrated systems in cars these days that aftermarket had to be almost gone, but no, it appears that many manufacturers have adapted by making processors that take the speaker level from a factory head and then allow you to add amps and your own speakers and then be able to tune for great sound.

I also have a complete Sony XES system that I've been meaning to install in my Toyota Yaris daily driver, just need to get amps and speakers.
