Installing new HU and speakers

Replacing the head unit
Contrary to what some stereo shops will try to tell you, it is easy to replace the Monsoon head unit. Since it is just an ordinary Delco radio, replacement is the same as for any standard GM product. There are three different sizes of head units that can be made to fit a Camaro or Firebird dash. HU sizes are expressed as DIN. The factory HU in Camaros and Firebirds is 1.5 DIN (the face is approximately 3" tall).
The most common size is single DIN (the face is approximately 2" tall). This is the size that was used in most cars since the 1950s. You will need a mounting kit to fit an aftermarket single DIN head unit in the 1.5 DIN opening. The mounting kit consists of brackets and a faceplate to fill up the dash opening. The Metra part number for these single DIN kits are:
99-3009 Camaro 93-96, Firebird 93-02
99-3300 Camaro 97-02
99-4000 Camaro and Firebird with CD pocket
Many recent model vehicles have double DIN stereos (the face is approximately 4" tall). They have the advantage of being large enough to incorporate such features as GPS systems, DVD video, and touch screen displays. Double DIN head units can be installed in late model Camaros and Firebirds but they require a custom trim bezel with the larger opening to fit the head unit face. Custom bezels are available commercially (including through our sponsors), can be made by modifying the existing factory bezel, or can be created from scratch. An example of a double DIN installation with a bezel made from scratch is in this thread: Pioneer AVIC-D3 Installed.
Although not strictly necessary, you should get a wiring harness adapter kit so that you can connect your aftermarket HU without having to cut the factory wiring harness. The Metra part number for the wiring harness adapter is 70-1858. The adapter harness has a plug that matches the factory radio harness and a number of unfinished wires in industry standard colors. You simply connect the unfinished wires to the matching wires from your aftermarket head unit (i.e. red to red, orange to orange, etc.) then the whole assembly just plugs into the factory wiring harness. Even if a previous owner has butchered the factory harness by cutting off the plug and splicing wires, you can repair it and use a harness adapter. Metra part 71-1858 is a replacement plug and wires for the factory radio harness (71-1858 connects to the factory wiring and 70-1858 connects to the aftermarket radio wiring and then the two adapters plug together).
Finally, you will need an antenna adapter to fit the small GM antenna plug into the standard Motorola antenna port on your new HU. With these parts it is a simple matter to install your new HU and connect it to the factory wiring. Depending on the head unit you install, you should notice an improvement in sound over stock because of the reduced distortion. The difference won't be dramatic but it will be noticeable and you will be able to use higher volume levels than the stock setup without the sound becoming horribly distorted.
Steering wheel controls
Replacing the factory HU doesn't necessarily mean losing the use of your steering wheel controls. PAC (Pacific Accessories Corp.) makes a series of adapters that allow you to use the steering wheel controls with popular models of aftermarket radios. There are models designed to work with specific brands and a universal model that will work with most radios that have infrared remote controls. The "universal" adapter is the SWI-X which works with most head units that come with an infrared remote. The notable exceptions are JVC models and certain older Sony models. Check the PAC website for details.

Put that with some good components and a good amp. It will sound real nice

the "Camaro SS" is blue LED backlit and it wired to my headlight dimmer switch.
I used theyre supplied tape like they said. It doesn't bother me, matches the rest of the headunit.
Whatever though, if you like it, keep it that way.
