Installation—Ampliﬁer Mounting (cont.)

Passenger & Trunk Compartment Mounting

If the ampliﬁer is mounted under a seat, be sure that the vents do not become blocked. Do not allow seat padding or other obstructive material to press down on the ampliﬁer.

All Boston GT ampliﬁers have top panel controls. If the ampliﬁer is mounted under a seat, position the ampliﬁer so the cover panel can be removed with the seat forward or back to allow adjustment of the audio settings.

When mounting in a trunk, choose a location that will be protected from slid- ing cargo or other materials. Mount the ampliﬁer to solid surfaces only. Do not mount to plastic trim panels. Do not mount the ampliﬁer with Velcro, double- stick tape, or by wedging into position. Ampliﬁer should be mounted using the movable mounting feet and the provided mounting screws.

Installation—Fuses & Wiring

Ampliﬁer Fuses

Although the ampliﬁer has internal fuses, additional fusing should be provided at the battery on the positive (+) power wire going to the ampliﬁer. An inline fuse should be installed at no more than 18" (46cm) on the positive (+) power wire. The rating of the inline fuse should equal the value of the internal fuses of the ampliﬁer if only the ampliﬁer is connected to this wire. If other devices are connected to this wire, the fuse value should be of sufficient capacity to handle the demand.

Wire Gauge

The ampliﬁer accepts up to 4-gauge stripped wire at the DC power and ground input terminals, and 4-gauge is recommended. Wire runs should be kept to the minimum practical length.
