Automotive amplifier SWAT M-4.100 Review

The unit, which rattles at low volume when cold, after the auto factory, the rattle disappears, you have to finish it in the electrical workshop for power, and install fan cooling so that it does not overheat from the 180 watt speakers, after that it works stably

The amplifier works in class B, hence the disgusting step that is well audible at low volume, especially if the acoustics are highly sensitive. Plus clumsy execution of crossovers.

Sub alpine 1200 does not pump. Speakers in front of 150 350 pioneer plays better than from the radio pioneer 6 to . For a subwoofer worth 1.500 matchmaker knocks down as it should.
