BLAUPUNKT 1600W 4-Channel, Full-Range Amplifier AMP1604, Black

Great amp. Worked for my install of a couple 12" subwoofers in the back of a 240sx. Recommended- not sure if rated watts are legit, but the system sounds alright!

This is a great amp for the price. I was a little hesitant to purchase it but I’m truly glad I did.

Good for the price

I use these power in-ceiling speakers in my home. I first tried using a single amp and speaker selector as shown on the right of picture. Using these Blaupunkt Amps to power four speakers in 1-2 different zones is SO MUCH better. Using the Alexa ap, I can play different songs, at different volumes, in different zones, or have them all act in concert. The sound quality is solid and the power good at literally a fifth of the price Sonos charges. Also at the same sound output, these amps stay relatively cool compared to my SSL amp that gets quite hot. I plan on purchasing more to kill the speaker selector altogether and add some additional bedrooms.

I installed this on a boat in a covered area and it is running fine and the sound is good. I have not had the boat on water but it should be fine. I added some vibration material to dampen boat vibration. This also gives the vent holes on the bottom of the amplifier room for air to circulate. Looks like a good amp.
