Congratulations on your purchase of a Quantum Audio

®

 state-of-the-art power amplifier. 

Your selection of a Quantum  Audio

®

 car audio product indicates a true appreciation of fine  

musical reproduction.   Whether adding to an existing system or including your Quantum  

Audio

®

  amplifier  in  a  new  system,  you  are  certain  to  notice  immediate  performance  

benefits. 

A power amplifier’s performance is only as good as its installation.  Proper installation will  

maximize the system’s overall performance.  It is recommended   that you have our  

product installed by an authorized Quantum Audio

®

 retailer 

. . However, if you decide to  

install it yourself, please carefully read through this manual and take your time to do a  

quality installation. 

Due to continuing product improvements and possible manual revisions, we recommend  

checking our website for latest product information at www.quantumauio.net. 

Exposure  to  high  power  sound  system  can  cause  hearing  loss  or  damage. 

Listening to your system at loud levels while driving, will impair your ability to 

hear traffic sounds and emergency vehicles. Use common sense when listening 

to your system.

IMPORTANT!   Before making any connections, disconnect the car’s battery until  

the installation is completed to avoid possible damage to the electrical system.

Fuse   Amplifier’s 

   Power   Wire   At   The   Battery 

Be   sure   to   fuse   the   power   wire   within   12”   of   the   car's   battery.    This   will   protect   the   car's  

battery   in   case   of   a   short   circuit   between   the   power   amplifier   and   battery.    THIS   IS   A  

MUST,   t he   amplifier's   built-in   fuse   will   only   protect   the   power   amplifier   not   the   car's  

battery! 

Use   High   Grade   Wire   Connectors 

T o   ensure   maximum   power   transfer   and   secure   safe   connections,   it   is   recommended   to  

use   high   grade   barrier   spades   (for   connection   at   amplifier)   and   terminal   rings   (for  

connection   at   battery). 

Do   Not   Run   Any   Wires   Underneath   Vehicle 

Exposed   wires   have   a   chance   of   being   cut   or   damaged.    It   is   best   to   run   all   wires   through  

the   vehicle   under   the   carpet   and/or   side   panels.    This   lends   to   a   cleaner   installation   and  

less   risk   of   damage. 

Use   Caution   When   Mounting   Amplifier 

Remember   there   are   many   electrical   wires,   gas   lines,   vacuum   lines,   brake   lines   as   well  

as   a   gas   tank   in   the   automobile.    Make   sure   you   know   where   they   are   when   mounting   the  

amplifier   to   avoid   puncturing   lines,   shorting   wires   or   drilling   holes   in   the   gas   tank. 

Run   Signal   Wires   Away   From   Electrical   Wires 

To   avoid   possibility   of   induced   noise   from   the   car's   electrical   system   (i.e.   popping   noises  

or   engine   noise),   run   wires   away   from   the   car's   electrical   wiring. 

Make   All   Ground   Wires   As   Short   As   Possible   And   At   The   Same   Point 

In   order   to   reduce   the   chance   of   ground   loops   (i.e.   engine   noise),   make   the   grounding  

wire   as   short   as   possible   to   reduce   the   wire's   resistance.    Also,   when   using   multiple  

components,   make   sure   all   units   are   grounded 

  at   the   same   point. 

Avoid   Sharp   Edges   When   Running   The   Wires 

T o    avoid   the   possibility   of   power,   signal   or   speaker   shorts,   be   careful   not   to   allow   the  

amplifier’s   wires   to   come   in   contact   with   sharp   edges.    Use   a   grommet   to   protect   the   wire  

when   running   through   the   fire   wall   .  

Take this time to attach your sales receipt to the manual and put it in a safe place.  In case 

of any unforeseen reason this product may need warranty service, your receipt will be 

necessary to establish purchase date.
