Introduction
With the QSA8.2, we are introducing a
low-profile amplified subwoofer.
Low enough to easily fit below the
seat of your car, this system offers
you a quick and easy way to add a
high-powered subwoofer system to
your audio system.
The integrated amplifier features both
high pass and low pass crossovers,
and a control for adjusting the input
sensitivity from 0.2v to 6v.
Both high level (speaker level) and low
level (RCA type) inputs are present,
making this a universal solution for use
with any head unit or other input
source.
For further flexibility in the use of the
subwoofer, a variable bass boost
control has been included. You can
control the subwoofer level with the
remote level control module.
