Installation
Status LED’s -
These lights indicate when the amplifier is powered up normally and when there is a protection fault. The Protect
LED is laminated when there is a problem with your amplifier. Please contact your authorize CVM dealer or call CVM’s technical support.
1
LPF Crossover Adjustment -
Use this adjustment to select the crossover point. Remember that you must select the Low Pass
position (LPF) of the crossover adjustment switch first. The range of adjustment is limited between 50-250 Hz.
4
HPF Crossover Adjustment -
Use this adjustment to select the crossover point. Remember that you must select the High Pass
position (HPF) of the crossover adjustment switch first. The range of adjustment is limited between 50-250 Hz.
2
Vega Bass Boost -
This control adds 0 to +9dB of boost at 45Hz. Be cautious when adding boost to some subwoofer systems as
they may not be able to handle the additional low frequency boost. In the 0dB position, no bass boost is added.
3
Crossover Selection Switch -
This switch allows you to select the crossover. Use High Pass for midrange or high frequency
speakers. Use Low Pass for subwoofers. In the FLAT position, neither crossover adjustment knob has an affect and all speakers will receive the
full frequency range.
5
Input Gain Adjustment -
This control matches the preamp stage of the Cerwin-Vega Mobile amplifier to your source unit.
This is NOT a volume control. The range is between aprox 200mV and 6V.
6
RCA Input -
The RCA jacks allow for a normal Left and Right channel signal input. Simply connect to the source unit using RCA type
audio cables, keeping them away from power wiring wherever possible to reduce risk of noise.
7
Power Input Connections -
These connections are for input power, chassis ground, and remote turn-on. Use a minimum of
8 gauge wiring for power and ground connections. 4 Guage is recommended for the mono block. The terminals will handle up to 8 gauge wiring
with no problem whatsoever(4 guage on the mono block). Be sure any wiring that passes through metal has a grommet!
8
Power Fuses -
Standard automotive type ATC/ATO fuses are used on Cerwin Vega Mobile amplifiers. Always replace with the correct fuse
size. Never insert fuses of higher values. Doing so will void the warranty of your Cerwin Vega Mobile amplifier. Also include a main fuse at the
connection to the vehicle battery within18 inches of the positive battery post. It is also important to upgrade the connection between the negative
battery post and the chassis of the vehicle. This greatly reduces possibilities of weak electrical “links” in the circuit.
9
Speaker Output Terminals -
Connect your speakers to these terminals. Stereo connections are connected as labeled. Bridged
connections use the LEFT + and RIGHT - as the two connections. The 2 and 4 channel amplifiers will perform into 2 Ohm stereo loads or 4 Ohm
bridged loads. DO NOT run 2 Ohm bridged loads on these amplifiers! The mono blocks will run 2 ohms mono, BUT NOT 1 ohm mono!
10
Remote Level Control -
This port is for the remote level control (included). The control is intended to allow the user to control the
level of gain up to the maximum adjustment level set on the amplifier. The control does not add additional boost, it only attenuates the setting that
is fixed at the amplifier’s control panel.
11
High Level Input -
Use these inputs when there is no low-level RCA output available from your source unit. Connecting your Cerwin
Vega Mobile amplifier directly to the vehicle’s factory radio would be a perfect example of this.
