High performance 2-channel mobile audio amplifier

Available Finishes:

Pure Performance.

This amp proves that small is big. Stereo, bridge-mono, or simultaneous stereo/mono operation provide total setup versatility. Power output is 90 Watts RMS x 2 channels at 4 ohms and ≤ 1% THD+N; signal to noise ratio: -70 dBA (reference 1 Watt into 4 ohms); Additional Power: 125 Watts RMS x 2 channels at 2 ohms and ≤ 1% THD+N

PA250.2 Features:

2 ohm stable stereo operation is capable of driving virtually all automotive speakers.

125 watts x 2 (2 ohm) continuous power; 200 x 2 (2 ohm) dynamic power; 250 x 1 (4 ohm) continuous power.

High-speed MOSFET switching power supply and high current bipolar output transistors pump maximum voltage and high current to your speakers or subwoofers.

Double layer fiberglass epoxy printed circuit boards for more rigidity, less shrinkage and a smaller overall amp footprint.

6-way Smart System Protection (SSP) circuits

Selectable 12 dB/octave high or low-pass crossover with fixed crossover frequency. Defeatable for full range (flat) operation.

Switchable 8 dB bass boost at 40Hz for extra bass thump.

Variable input gain optimizes match with different signal sources (250mv to 7.5V).

RCA outputs for easy daisy chaining of other amplifiers.

Mounting hardware with rubber isolation grommets and extra fuse included.

Light bar/fan output-Connect an optional LED light bar or cooling fan for custom installations.

Multi-color status LED gives instant information on amplifier operation.
