Review of Amplifier:Stetsom v1k5 H - 1 ohm
I initially purchased this little amplifier to power my 13w6v2 loaded Stealthbox in a 2006 Mustang GT. The main goals were to have a lot of power in a small, efficient, form factor. From that perspective, the Stetsom delivers because it is a small yet powerful amplifier. When it comes to sound, this amp doesn't miss a beat.
Thus far, I tested some old Pink Floyd, mainly Echoes from Meddle and all of Dark Side of the Moon. This amplifier does not miss a beat when it comes to reproducing sub bass frequencies and it literally feels like one's finger is sliding up and down the bass guitar string during reproduction. I also put Thirteenth Step by A Perfect Circle on, and again, this little Class D sounds just as good as any high end Class AB amplifier that I ever tried in my vehicle. Sonic wise, I am truly impressed with this little gem and it is a vast improvement over the first gen Class D amplifiers that absolutely hated.
Now for the bad. The fan on this amp is super loud. I'm talking I hear it in the trunk over my Mustang's exhaust and fuel pumps during the quiet musical passages while driving down the highway kind of loud! I also noticed that this amp is super sensitive to rapid voltage changes. If I drive like a bat out of Hades, the sudden increase in RPM spinning the alternator up sends the amp into protect mode. As a result of these two negative points, I will be pulling the amp from my vehicle and putting it up for sale shortly.
So to recap, it's a small, powerful amp that sounds great BUT has a super loud fan with a super sensitive voltage protection circuit. I thought this was the perfect Class D amp for me, but it just isn't going to work out.
