Using a small list of parts, you can update the stereo in your CRX to sound great and look 100% original. Additionally since you can add a deck with CD changer controls you can aso have iPod/mp3/wma support (through the CD changer port). Very clean.
UPGRADE
List of parts needed:
(Note: this install guide assumes you have the factory plug for the stock radio intact)
New deck (I used Honda part # 39100-S84-A41RM – I found this used and it fits perfect) this deck matches the CRX interior really well, says HONDA on it and has CD changer controls. There are a plethora of other Honda decks out there, and as long as it is not a funky shape, you could make it work with this simple method. Although I used a single DIN unit you could use a double DIN if you desired by eliminating the tray below.
Wiring harnesses You will need two harnesses/plugs. One is to plug into your factory wiring harness. For the 1990 CRX use this one: Stereo Wire Harness Honda CRX 88 89 90 91 (car radio wiring installation parts)
Take the 2 harnesses and wire them together. Match wire for wire, function for function. Matching the colors is pretty much all you need to do but use this as a reference: http://www.installdr.com/Harnesses/HA-Wiring.pdf
There may be some wires left over after the grafting. Features that are not on the CRX (power antenna etc) are supported by the new deck and not the car, these can be left disconnected.
Now, simply take the harness you made and plug-and-play. Plug one end the harness into your factory wiring and the other into your new stereo. Congratulations, welcome to whatever year your new deck is!
And if you used a deck with CD changer controls, you can run one of these accessories: Direct Audio Input From iPod Dock Connector to Honda 1998-2004 Radio w/CD Changer Input

What If I wanna run an amp?
If you run an amp, who cares if your dash looks all factory? is your exhaust so lound that you need an amp?
your CRX site is good, is this for one car?
