Connect speakers  
Connect car audio  
Option 1: Line input connection  
Connect the amplifier to the car audio with an  
RCA cable (not supplied).  
Note  
Use speakers with an impedance of 2 to 8 ohm  
(4 to 8 ohm when used as a bridged amplifier).  
Match the “left”, “right”, “+” and “-” terminals  
correctly. Revised polarity may degrade sound  
quality.

mode when woofer and subwoofer  
are connected for low frequency  
output.  
1 Set FILTER MODE at OFF or LPF mode.  
2 Slide BASS BOOST to 12dB position.  
Tip  
If BASS BOOST is set at 0dB position, no extra  
bass will be boosted.  
OFF (flat): Select this mode when  
both tweeters and woofers are  
connected.  
Note  
If FILTER MODE is set at HPF mode, the bass  
frequency will be filtered.  
Select LPF frequency  
When FILTER MODE is set at LPF position, you  
can select the range of frequency that is to be  
filtered.  
About the protector  
indicator  
The amplifier has a built-in protection circuit to  
protect the transistors and speakers in following  
conditions:  
Note  
When FILTER MODE is set at OFF or HPF  
position, LPF FREQUENCY does not work.  
The amplifier is overheated.  
A DC current is generated in  
speakers.  
1 Slide LPF FREQUENCY to the selected  
position.  
80Hz: More high frequency signal  
is filtered. Select 80Hz if you prefer  
stronger bass effect.  
180Hz: Less high frequency signal is  
filtered.  
The battery voltage is too low or too  
high. Or  
The speaker terminals are short  
circuited.  
When the PROTECTED indicator  
lights up in red, the amplifier shuts  
down automatically. In this case
