Founded in the early 1950s, Aiwa has built a reputation for quality audio products and industry leading innovations. The company made a name for itself with the release of the first Japanese tape deck, the TP-707, and has focused on consumer audio products ranging from home and car stereos to microcassette recorders.
CDC Z127 Features
The CDC Z127 features 45 watts of power emanating from four speakers. Sound sources include an integrated CD player, radio tuner and front panel, as well as a 1/8-inch audio input jack for auxiliary or MP3 audio. An adjustable digital dimmer controls the control and front face lighting. Preamp outputs are available as RCA connectors on the back for subwoofer connections. The installed size is 7 1/4 inches wide, 2 1/8 inches high and 6 1/8 inches deep.
Speaker Wiring Harness
The Aiwa is connected to a car's speaker system via a Sony-styled multi-pin wiring harness. This harness includes all speaker connections, unit main power, unit constant power (used to keep the unit's time and radio presets correct when the car is turned off) and integrated dimmer controls (when available from the car's digital computer). Wiring the Aiwa's wiring harness with the car's custom wiring harness completes all required electrical connections.
Speaker Color Codes
Each speaker requires two connections: one for the speaker's positive terminal and one for the speaker's negative terminal. A four-speaker system requires eight separate connections that are colour coded for identification. The front right speaker's positive wire is dark grey, and its negative wire is dark grey with a black stripe. The front left speaker's positive wire is white and its negative wire is white with a black stripe. The right rear speaker's positive wire is purple, and its negative wire is purple with a black stripe. The left rear positive wire is green, and its negative wire is green with a black stripe.
A few specialised tools are required for a clean installation. DIN removal tools assist in the removal and physical installation of units such as the CDC-Z127. Wire strippers and clippers are required for the electrical wires, in addition to crimp connectors and a crimper hand tool to complete the connections. Flathead screwdrivers are used to bend installation bracket tabs into place, while Phillips head screwdrivers are used to remove the car's interior panels to gain access to the radio location.
