Product Description

Alpine KTA-30FW Tough Power Pack Compact 4-Channel Amplifier

Alpine KTA-30FW Tough Power Pack Compact 4-Channel Amplifier is a super-compact, weather-resistant power pack to give you higher power output and better dynamic range for open-air vehicles, such as ATVs, side-by-sides, motorcycles, and boats. This Class D amplifier can be used with factory head units or aftermarket sound systems. The KTA-30FW comes with a single harness with all of the power, input, and output connections, terminated with a water-resistant 26-pin connector.

Dynamic Peak Power (DPP)

The KTA-30FW is equipped with a new dynamic power supply design that provides a burst of power when needed. Dynamic Peak Power (DPP) technology increases the internal gain level when more power is needed, effectively doubling the output power to give you better dynamic range at high volume.

Power Output

The KTA-30FW has the following power output specifications:

CTA-2006-B Power Spec

75 watts RMS x 4 (at 2 ohms and 4 ohms, 14.4V, ≤ 1% THD+N)

Dynamic Peak Power Spec

150 watts x 4 (at 2 ohms and 4 ohms, 14.4V, ≤ 1% THD+N)

Weather Resistant

The power pack is ideal for side-by-sides, boats, motorcycles, and other vehicles that may be exposed to the elements. The KTA-30FW has an IP66 weather-resistance rating for protection against moisture and dust.

Connections

The weather-resistant OEM-grade Tyco 26-pin connector is for all needed amp connections, including the following:

Power/Ground

The connector has 12″ 10-gauge power (red) and ground (black) pigtails. The red power wire has a large, in-line noise filter. There is no internal or in-line fuse, so you’ll need to add a 30A fuse near the battery’s positive (+) terminal.

Remote Turn-on

There are two remote leads on the connector. Connect the blue/white Remote Turn-on lead to the +12V remote turn-on or power antenna lead from the head unit. The solid blue Remote Out lead can be used to turn on additional amplifiers. If your head unit does not have an amplifier turn-on lead, see Alternate Turn-on Options (below).

Inputs

The amplifier will accept either line-level or speaker-level inputs. The amp’s input wires are color-coded twisted pairs with female RCA jacks. If your source unit has RCA outputs, you can simply connect RCA cables to the amp. If the source unit does not have RCA outputs, you can cut off the amp’s RCA jacks and splice the source unit’s speaker wires to the twisted pair inputs. (Color codes: Front left: white, Front right: gray, Rear left: green, Rear right: purple)

Speaker Outputs

The connector has speaker output wires for four speakers. These 20-gauge speaker wires follow the same color coding as the input wires (see above).

Alternate Turn-on Options

If the source unit does not have a traditional amplifier turn-on lead, or if the power antenna lead is activated only when the radio is on

Switched Power Source

The remote turn-on lead of the amplifier can be connected to a switched power source (ignition) in the vehicle. A 3A fuse should be installed close to the ignition tap. The amplifier will stay on as long as the ignition switch is on.

Separate Switch

A SPST (single-pole, single-throw) switch can be installed on the amplifier’s turn-on lead. Again, a 3A fuse should be added near the power source. The switch should be placed where it is accessible by the driver. The switch will need to be turned off when the vehicle is not running to avoid running the battery down.
