Features	The BLAST Port is used to connect the Remote Bass Level

	Controller and for transferring control signals from one SX
	amplifier to another SX amplifier. An RJ45 cable is required to
	connect the BLAST Port (Out) of one amp to the BLAST Port
	(In) of another. This is only required if you want to control
	more than one amplifier with the same Bass Level Controller.
	More details on this further in the manual.
	The speaker terminals are custom-machined connectors
	with full protective shrouds and are designed to accept heavy
	gauge speaker wire assures maximum power transfer and
	damping with minimal power loss.
	Gold-plated RCA input connectors and PAST jacks provide
	solid input and output connections for your pre-amp signal.

Custom-machined power block accepts up to a 2 Ga wire for both power and ground connections and up to an 8 Ga for remote turn-on assures maximum power transfer with minimal loss.

On-board fusing (number of fuses vary by amp size) to protect amplifier against over current conditions and reverse polarity.

Power LED indicates amplifier is powered up and operating.

Check Fuse LED indicates a fault with the end panel fuses. This could be fuses which are not seated properly, faulty fuses or blown fuses.

NOTE...

SX1250.1 does not have on-board fusing or the Check Fuse LED due to larger external fusing requirements.

Mounting

When selecting a location to mount your Kicker amplifier be sure it is structurally sound and that there are no items behind the area that could be damaged by the screws. Check for wiring, brake lines, fuel lines, gas tanks, etc.

All amplifiers generate heat under normal operation. Be sure to choose a location that allows adequate ventilation for the amplifier. Also consider that the air temperature inside an automobile’s trunk can reach upwards of 140 degrees fahren- heit. An amplifier mounted in the trunk may require additional cooling such as extra fans moving air around the amplifier’s chassis or ventilating the trunk to exchange the hot air in the trunk for cooler air outside. If possible, mounting the amp in the passenger compartment will allow cooler operation.

Remember that the controls on top of the amp will need to be accessible for adjustment later. Keep this in mind as you choose your amplifier’s mounting location.

Now that you are ready to mount your amplifier, use the supplied 3mm allen wrench to remove the amplifier EndKaps. This will give you access to the mounting holes in the amplifi- er and all wiring connections.

With the EndKaps removed, you now have access to the four mounting holes in the mounting feet and all wiring connections. Drill 4 holes using a 7/64” drill bit and use the supplied #8 screws to mount the amplifier.
