WOOFER MOUNTING CONSIDERATIONS
• All woofers require a rigid baffle and isolation between the front and back of the
speaker for best low-frequency extension.
• The 660GTi woofer may be used in an infinite baffle or in a small sealed enclosure
with a volume equal to or larger than 1/8 ft

.
• The GTi competition speaker systems include a choice of grille trim. See Figure 19 to
change to the carbon fiber grille trim.
TWEETER MOUNTING CONSIDERATIONS
• Use the waveguides, if possible.
• The waveguide requires a hole 4" in diameter for mounting.
• Aim the tweeters at a point in between the two front-seat positions,
if the waveguides will be mounted in the A-pillars or kick panels.
ADJUSTING THE CROSSOVER
• If you are bi-amping the speakers, remove the jumpers, as illustrated in Figure 20.
• If you are using the waveguides, move the switch to the "Waveguide" position.
• If you are not using the waveguide, move the switch to the "No Waveguide" position.
• After installing the system, set the "Tweeter Level" switch according to your
preference.
See pages 14–19 for dimensions, mounting and wiring diagrams, Thiele/Small
parameters and performance graphs.
