NOTE FOR STAGE 3 and 5 SYSTEMS

 – 

An optional second subwoofer amplifier 

mounting plate (MBQX-SUB-ACC-1) for Stage 3 or 5 Systems already containing one 

subwoofer and 400 watt amplifier is available at MBQuart.com. This accessory item is 

required for the amplifier in this kit because the dual amplifier mounting plate installed 

in Stage 3 and 5 systems is already populated with two amplifiers and contains one 

subwoofer. Instructions on this accessory mounting plate and how to install this kit as a 

“SUB 2” add-on are included in this manual.

NOTE FOR HARDWARE - 

Hardware for mounting components to enclosures and other installation-related 

items you will need are contained within the packaging for each piece. Do not dispose of any packaging until 

you have completely installed your system and are certain you have accounted for every piece.  If you feel 

something is missing, please contact Maxxsonics directly via email – [email protected]

WARRANTY

Your audio system is covered by a 1 year warranty from the date of invoice. It is important to retain your 

sales receipt. Furthermore, it is crucial that you record and store a record of the serial numbers for each of 

the components that are included in your system. In the rare instance that a warranty claim is needed both 

proof of purchase and serial numbers are required. Additional information on the back page.
