 Speaker Output Terminals
•  The speaker output terminals of this unit are 
insert terminal.
Be sure to observe correct speaker output 
connections and polarity in relation to the other 
speakers in the system. Connect the positive 
output to the positive speaker terminal and the 
negative to negative. 
About Subwoofer Input/Output Terminals
•  
The input is stereo but the output is monaural.
•  Reversing subwoofer polarity may be desirable 
in some installations for optimum bass 
performance.
About Bridged Connections
In the bridged mode, connect the left positive to 
the positive terminal on the speaker and the 
right negative to the negative terminal of the 
speaker. Do not use the speaker (–) terminals as 
a common lead between the left and right 
channels.
Use a Y-adapter (sold separately) for the input 
when bridging the outputs. (Refer to the 
“BRIDGED CONNECTIONS” on page 13.)
NOTE:
•  
Do not connect the speaker (–) terminal to the 
vehicle’s chassis.
 RCA Input Jacks
Connect these jacks to the line out leads on your 
head unit using RCA extension cables (sold 
separately). Be sure to observe correct channel 
connections; Left to Left and Right to Right.
 Fuse
PDR-V75 ...............................................................40 A x 2
USE THE CORRECT AMPERE RATING WHEN 
REPLACING FUSES.
Failure to do so may result in fire or electric 
shock.
 Power Supply Terminal
 Remote Bass Control (Option)
Connect the Remote Bass Control Unit (sold 
separately) to adjust the output level remotely. 
This is not to replace appropriate gain level 
setting between the amplifier and head unit.
 Battery Lead (Sold Separately)
Be sure to add an in-line fuse with the battery 
lead as close as possible to the battery’s positive 
(+) terminal. This fuse will protect your vehicle’s 
electrical system in case of a short circuit. See 
below for appropriate fuse value and minimum 
wire gauge requirement:
PDR-V75 ..................... 80 amp fuse, 4 AWG/21 mm
2
 Ground Lead (Sold Separately)
Connect this lead securely to a clean, bare metal 
spot on the vehicle’s chassis. Verify this point to 
be a true ground by checking for continuity 
between that point and the negative (–) 
terminal of the vehicle’s battery. Ground all your 
audio components to the same point on the 
chassis to prevent ground loops while keeping 
wire length as short as possible.
Minimum required wire gauge for this 
connection is as follows:
PDR-V75 ................................................4 AWG/21 mm
2
 Remote Turn-On Lead (Sold Separately)
Connect this lead to the remote turn-on 
(positive trigger, (+) 12V only) lead of your head 
unit. If a remote turn-on lead is not available, see 
“CONNECTION CHECK LIST” section on 
page 8 for alternative method.
NOTE:
•  
When connecting the speaker output leads of 
the head unit to this unit with an RCA 
extension cable (sold separately), etc., you do 
not need to connect the remote turn-on lead, 
owing to the “REMOTE SENSING” function of 
this unit. However, the “REMOTE SENSING” 
function may not work depending on the 
signal source connected. In such a case, 
connect the remote turn-on lead to an 
incoming power supply cord (accessory 
power) in the ACC position.
