The Q SELECT switch determines the width of boosted frequencies. A 'Q' of 2 (switch out) will give you a wide boost while a 'Q' of 4 will boost a narrow range of frequencies. (See char t below.) On the rear end panel you will find the control and the plug-in for an optional dash mounted level control.

(or nut, bolt, and star washer)

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 - 16 gauge or larger Grommets (sized to work with the power wire you plan to use

in your installation) Tube of silicone sealant

Fuse requirements

Amplifier Maximum Fuse Rating

PC1400 PC1800

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 vehic le from fire in case the po wer 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 . Use a po wer distribution block or fuse near y our amplifiers with the appropriate fuse for each individual power wire.
