Small, clean and powerfull

Installed inside the dash right behind the stock radio in a Subaru Crosstrek without major issues.

Great sound once you've got it tuned & the speaker level inputs + signal sensing turn-on make integrating it into the stock system easy.

The only thing that would have made it easier would have been screw terminals instead of wire pigtails.

The one problem I have is probably a Subaru, not a Soundstream issue... after the install, my Starlink (Subaru remote telematics) light is on. This may be due to an interaction between the amp and the DCM (data communications module). I'll have to work this out w/Subaru.

My only complaint about value is that it went on sale the week after I bought it!
