Here it is: Alpine S2-A36F
Alpine S-Series amplifiers have carried the reputation of legendary amplifiers on their shoulders for years.
The Alpine S-A32F and S-A60M were Alpine's best-selling amplifiers throughout their existence, and now both of these amplifiers have become available in new, even more improved "S2" versions!

Hi-Res Audio certified
The new generation S-Series S2-A36F is Hi-Res Audio certified and the four-channel amplifier is capable of playing music up to 40kHz. This ultra-wide reproduction range is exceptional in this price category, and Alpine's new S-Series amplifiers are the perfect pair for the Alpine S-Series speakers, which are naturally also all Hi-Res Audio approved.

Made for all systems
S2-A36F is also compatible with new cars, where the player cannot be replaced, but you still want better sound reproduction in the car. The amplifier can turn on and off at the right time, and the signal can be fed to the amplifier at speaker level without an excitation cable, speaker level with an excitation cable, and line level with an excitation cable.

Easy to install and use
All the settings of the amplifier can be found at the end of the amplifier, which makes it easier to adjust if the amplifier is installed e.g. under the bench or in vans behind the front seats in the partition.
With the amplifier's removable end pieces, you get a simple and elegant installation.

Mid-Bass EQ
Do you need more kick in the mid-bass? The S2-A36F includes a unique Mid-Bass EQ, with which you can emphasize the frequency of one hundred hertz on a scale of 0 to +12dB. It should be noted that the input sensitivity of the amplifier should be adjusted again when the Mid-Bass EQ settings are changed.
