SoundXtreme ST-3600.1 Monoblock Car Amplifier

The SoundXtreme ST-3600.1 is a monoblock car amplifier designed for powering a dedicated subwoofer system. Its single-channel layout focuses amplification on low-frequency reproduction, making it suitable for vehicle audio upgrades that need separate bass amplification. The amplifier is rated for stable operation with 1-, 2-, or 4-ohm speaker loads.

With a stated maximum output of 3600 watts at 1 ohm, the ST-3600.1 is intended for systems where subwoofer output and adjustable bass level are priorities. Its Class AB design provides a traditional amplifier platform for a dedicated bass channel. A variable gain control helps match the amplifier to the signal level of compatible source equipment.

The included remote subwoofer level control gives the driver a convenient way to adjust bass output from the listening position. This can be useful when music recordings, listening preferences, or road noise call for different low-frequency levels. The amplifier also includes LED power and protection indicators for at-a-glance operating status.

Input adjustment is supported by a 200 mV to 6 V input-sensitivity range and a 22 kOhm input impedance. A variable low-pass filter from 50 Hz to 250 Hz lets the amplifier send an appropriate bass range to a connected subwoofer. Its specified 10 Hz to 30 kHz frequency response provides flexibility when integrating the amplifier into a vehicle audio system.

The ST-3600.1 uses chrome-plated RCA connections and is built in a compact amplifier chassis. It can serve as the bass section of a system with an aftermarket receiver, signal processor, and properly matched subwoofer enclosure. Select subwoofers and wiring according to their actual impedance, power-handling specifications, and the amplifier's installation requirements.

Key Features

Design & Installation

The ST-3600.1 is a Class AB monoblock amplifier with chrome-plated RCA connections, chrome-plated speaker terminals, variable gain control, and LED status indicators. Its listed product dimensions are 10.5 × 2.5 × 13.3 inches, helping it fit where a low-profile amplifier mounting location is available. The chassis is intended for surface mounting in a vehicle audio installation.

Install the amplifier securely in a ventilated location and use a subwoofer configuration that presents a supported 1-, 2-, or 4-ohm load. Connect a compatible low-level RCA signal source, set gain carefully, and use the low-pass filter to blend the subwoofer with the rest of the system. The included remote level control can be positioned within reach of the driver for routine bass adjustments.
