Congratulations...

On your purchase of our Coustic speakers engineered

specially for use in automotive environments. Over the years these
Coustic speakers will give you countless hours of unparalleled listening
pleasure while you are on the road.

However, to ensure that your Coustic speakers perform at

their highest level of efficiency, read the instructions thoroughly and
follow the precautionary steps and instructions as listed. That done, you
will then have superb sound reproduction from speakers designed
specifically by Coustic for use in automobiles.

But Coustic does not just manufacture automotive speakers,

we also build innovative power amplifiers, high performance
subwoofers, state-of-the-art real-time analyzers and esoteric electronic
crossovers. In other words, everything you need to create the ultimate
car audio.

INSTALLATION PREPARATIONS AND PRECAUTIONS

1. Make sure car audio system is turned off before speaker

installation begins.

2. Metal clips and filings should be kept away from speakers;

WORK AS CLEANLY AS POSSIBLE.

3. Install each speaker as firmly as possible. To maximize high

frequency reproduction, make sure there is no obstruction
between speaker and interior of the vehicle.

4. Make sure speaker cone has sufficient breathing room.
5. Speakers must be wired IN PHASE to produce the best

sound fidelity. Double check audio system for correct phasing
(i.e., “+”

➝ “+”, “-” ➝ “-”).

6. Before doing any cutting or drilling, check all clearances and

mounting locations again. Check position of both speakers
(not just one) in case car doors are not symmetrical (e.g.,
multiple electric window controls on the driver’s side only).

INSTALLATION
The HP46.4 is designed to fit European and GM vehicles with-
out extra adapters. Refer to the different installation applications
