Alpine S-A32F 4-channel S-Series Class D amplifier, with a power of 4 x 80W @ 2 Ohms

S-Series amplifier: a perfect match with speakers from the same line. It boasts very high heat resistance and does not shut down due to overheating. It also features excellent sound quality in its price range.

Alpine S-A32F fully digital design

Compact and powerful: the new digital amplification circuit allows high power while maintaining a reduced footprint. The S-A32F measures only 204 mm wide x 204 mm long for easy installation in practically any vehicle.

The new S-Series amplifiers are equipped with an improved heat sink circuit design and protection that eliminates thermal shutdown, for reliable music playback.

The speaker terminals and power cable terminals are conveniently positioned on the left side of the amplifier to allow for clean installation. The power cable terminals accept large gauge cables.

The 4-channel RCA speaker signal inputs accept low and high power signals. This simplifies connecting the S-A32F directly to the original car stereo system, regardless of the main unit's power output (RCA connectors with open cables are available separately).

You can connect the RUX-KNOB2 controller (optional, sold separately) to the S-A32F to control the subwoofer level directly from the dashboard (applicable for channel 3 + 4 in bridge mode for subwoofer use).

High Pass / Low Pass Filter. With this filter you can adjust the frequencies for door speakers or a subwoofer. You can then adjust the cutoff frequency for more precise tuning.
