TWO KX2500.1 AMPLIFIERS & ONE DVC SUBWOOFER
This diagram shows how to power a single Dual Voice Coil (DVC) subwoofer using two KX2500.1 amplifiers. For maximum power
output from your KX2500.1 to the subwoofer each voice coil should be 2
Ω
impedance. Do not connect to voice coils with an
impedance lower than 2
Ω
!
Be sure to properly power and ground each amplifier according to the minimum specifications shown on page 6 to insure proper
operation and maximum power output.
NOTE: The gain setting/output level on both amplifiers must be matched for proper operation. If the output level of both amplifiers is
not matched this will result in poor performance and possible damage to your subwoofer.
To properly set the levels you will need a test CD containing a 60 Hz test tone and a digital volt meter. Play the 60 Hz tone through
your CD player set at a low to moderate volume level. Next, measure the AC voltage output across each amplifier’s positive (+) and
negative (-) speaker output terminals. Turn the gain down on the amplifier which reads higher until it matches the other amplifier.
