Trunk Mount  (120-1967)  8-Inch Bandpass Box Speaker   Faxback Doc. # 15891
Amplifier                       (120-1731)

The Owner's Manual for our Trunk Mount Amplifier (Cat. No. 12-1967)
contains an error.  On page 12, it states that "When operating in the
bridged mode, the minimum speaker impedance is 8 ohms for each bridged
channel.  Operation of the amplifier below this impedance load can
damage both the amplifier and your speaker and voids your warranty."

Both statements are incorrect.  The 8-Inch Bandpass Box Speaker
(Cat. No. 12-1731), which has an impedance of 4 ohms, is safe for use
with the 12-1967 amplifier.

There's some concern about the heat generated when the 12-1967 is used
with the 12-1731.  (And yes, like any high-powered amplifier, the
12-1967 generates a log of heat-there's a lot of energy being pushed
to those speakers!)  That's why it's so important to mount the amplifier
in a well-ventilated area where it has room to "breath."  It should not
be mounted under a seat or in any other enclosed area.  Remind customers
who want to mount the 12-1967 in a trunk that they shouldn't place item
on top of it.

When using the 12-1731 speaker with the 12-1967 in the bridged mode, the
customer must use Y-adapters to sum the left and right channels (the same
way you would when using a subwoofer with a home theater system).  It's
preferable to use line-out (or low-level) outputs from the stereo to
the 12-1967 for this application.  If a customer wants to use the
12-1731 speaker with the 12-1967 amp and a stereo that doesn't have
line-out outputs, recommend our Car Stereo Speaker Level to RCA
Converter (Cat. No. 12-1337) to match the stereo's outputs to the
12-1967's LOW INPUT jacks.
