On the PCX 1250 amplifier, we offer tremendous control of your bass with QBASS™. On the front end panel of your PCX 1250 you will find the QBASS™ level control. Adjust the level control clockwise for up to 12 dB of boost at a factory preset frequency of 40Hz with a Q-factor of 2
CAUTION: QBASS ™ should only be used in systems with a strong subwoofer section. +12dB is a large amount of bass boost and may damage your speakers if abused.

NOTE: TOOLS ARE NOT SUPPLIED
Small flat blade screwdriver
Phillips screwdriver (#2 or medium sized) Wire cutters
Wire strippers
4 - #6 round head screws, and 1 - #8 sheet metal screw (or nut, bolt, flat washer star washer) [see detail]
2 - Ring connectors (large enough to accommodate your method of grounding)
In-line fuse or circuit breaker - see fuse chart below
Power and ground wire - see Power Wire Calculator on page 4 Speaker wire - 12-16 gauge
Grommets (sized to work with the power wire you plan to use in your installation)
Tube of silicone sealant
You will need to install an in-line fuse or circuit breaker in the power wire within 18" of the battery. This fuse or circuit breaker is to protect your vehicle from fire in case the power wire shorts to the vehicle body. If you are only using one amplifier, use the fuse rating indicated in this chart. If you are using more than one amplifier, add up the fuse ratings for all the amplifiers. This sum is the rating for your main fuse or circuit breaker. You may also want to add a power distribution block near your amplifiers to distribute large gauge power cable to multiple amplifiers.
