Review: I wanted to put a car sub into a home theater setting for music listening in the garage. Figured I would hook it up to a plate amp. This amp was best bang for buck for its claimed power output. I didn't expect TOO much out of this set up so I built a sub box out of 1/2" osb scrap from work, especially since the sub is dvc wired in series from 2ohm to 4ohm. It's actually performing so well that I now plan to build a proper box out of 3/4" mdf to actually get the full performance out of the amp and sub. This sub is rated at 800w rms btw. I'm impressed with this amp. I've only had it for a month so if it fails I'll come back and update
Review: I swapped out ancient 100w class ab amps for these in my little homebrew living room subwoofers. the power increase is fantastic. the amps run cool. i ran some bass mekanik tracks to run them in hard. i could feel port wind in my chair 15 feet away and the amps kept chugging. no csa, ul, or etl rating on these but the build quality and performance inspire confidence.

Als Austausch für mein defektes Aktiv Subwoofer-Modul in einen HK-TS11. Passt fast perfekt in meinen alten Harman Kardon TS11 Woofer. Ich musste bei der Platine nur die Kanten um 1mm mitm Multitool abnehmen und ich konnte es in das alte Gehäuse einsetzen. Die Leistung reicht bei uns locker für das ca. 30m2 Wohnzimmer. Günstige Alternative zu einem neuen Subwoofer, wenn nur das Modul defekt ist oder zum selbstbau eines Woofers. Die Einstellmöglichkeiten am Woofer sind vielfältig zum Justieren um den Klang für sich einzustellen… Einziger Kritikpunkt, die Auto-ON Schwelle könnte niedriger sein, wenn ich abends nicht zu laut habe, dann schaltet er öfters einfach ab. Das Problem wird aber in zukunft mit einer Master-Slave Steckdose gelöst…
