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 chart below). On the rear end panel you will find the an optional control. Adjust the level control clockwise for up to 18dB of boost at your selected frequency and Q.

Tools/Parts needed for Installation (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, 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 3 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

PC2400 PC2600 PC21400

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 fuse or circuit breaker. You may also want to add a power distribution block near your amplifiers to keep the wiring tidy.

2600 amplifier has two channels at 150 watts per channel RMS rating into 4 Ohms (150 x 2 = 300). You would use the formula in the following way:

300W x 2 = 600W 600W

= 50A Total current draw.

12V If the same amplifier is driven into a 2 Ohm stereo or 4 Ohm mono load,

double it's 4 Ohm RMS rating. All double their power at this load.

= 100A Total current draw.

for all of them and choose the appropriate gauge based on the grand total.

WIRING

Before beginning, disconnect the negative (-) terminal of the battery prior to working on the positive (+) terminal to prevent a short to ground. This is important, unless you want to spend the rest of your life with a nickname like Reconnect the negative terminal only after all connections have been made.

"Sparky,"

"Smokey."

Warning!

Fuse must be installed within 18" of battery
