Speaker Connections
Cautions:
1. Use ungrounded speakers only.
2. The speakers to be used with this unit should be able to handle more than 45W(CQ-MR505N),
40W(CQ-MR303N) of audio power. If an optional amplifier is used, the speakers should be able to han-
dle the maximum output power of the amplifier. Use of speakers with small input ratings can cause dam-
age to the speakers.
3. The speaker impedance should be 4 - 8
Ω
. If the impedance is too large or too small, it affects the out-
put and may cause damage to the speakers or this unit.
4. Do not use 3-wire type speaker system having a common earth lead. Never connect the speaker cord to
the body of the car. This unit uses the BTCL circuit, so each speaker should be connected separately
using parallel vinyl insulated cords.
5. The speaker cords and the power amplifier unit should be kept away (about 30cm apart) from the anten-
na and antenna extension cord.
6. Follow the connection diagram below carefully. Failure to do so may cause damage to both unit and
speakers.
¡ Unit will be damaged if speakers (Front, Rear) are not connected properly.
¡ Do not connect more than one speaker to one set of speaker leads.
