This is a pretty cool unit. Quality seems quite high for the price. Install is certainly more challenging than a one-piece stereo, but not a big deal. You have to carefully set position of each knob at correct width, depth, etc, which takes some time and trial-error to figure out.
I think it looks pretty darn good, I think it sounds OK, and as a surprise bonus I learned I can set the screen to scroll the name/artist of what my radio is playing...(I was jamming Black Crowes during below "on" pic) with RDS, just like my 2011 daily driver does...and an I-pod can plug into the aux jack to play whatever you want. And it gives me a clock, which is always nice.
Crutchfield sold it to me on sale for $149 including shipping to my door, and including the trim plate and chrome knobs you see for my Bird (I have 67 walnut bezel in my 68) which matches color and grain not perfect, but surprisingly well.
Sound? It's OK. Not bad. Not great. It's PLENTY loud and powerful for my tastes, and while I'm parked for winter at the moment I'm certain I'll easily be able to hear it with the top down on the highway, over my Flowmaster 40 duals. But it's certainly not a "thumper", and I think the bass sounds kinda muddy, it could use more treble, and I just wish there was more adjustability in sound quality range (it just has bass/treble, nothing else). Surely the average sound is a combination of sub-par speaker placement, less-than-ideal shape and material of the speaker cavities, my relatively low-dollar choice in speakers, and the quality and power output of the Retro-sound unit itself. But it certainly sounds a HECK of a lot better than a one-speaker AM radio!!! And I'd say it's on par with your typical basic no-frills system that's found in today's modern cars. Bose Hi-fi it is NOT. BUT, now that the hard work is done, it can clearly be upgraded. Remember I did this on a budget, largely as an experiment to see if it was even possible. So now that it is confirmed, I can invest in higher quality speakers if I want some day and easily swap them in probably 20 minutes. The Retro-Sound has pre-amp inputs, and I can add a subwoofer somewhere (maybe a small one under passenger seat...someday...not now). So I am certain there is more potential here with more investment.
All told, considering this entire stereo system cost me about $265 for the head unit and 4 speakers, plus about $15 in wire and misc materials, I think it was money well spent...and it will greatly enhance my enjoyment of this car on long road trips, of which I hope there will be many. I'm also pleased with the appearance overall, which I know is subjective. But in my opinion I don't think the speakers and stereo overwhelm the interior by looking overly obvious and hacked...although I fully realize that purists will HATE everything what they see here. Just wait until I get the Sebring seats set in there and watch 'em squirm...LOL.
