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

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.

Great budget 4 channel amp with a lot of features. You can adjust the gain on each channel, use 2 for subwoofer and 2 for door speakers. Has HFP, LPF, and hrz adjust on each channel. Used this for door speakers and the Blaupunkt 1501 monoblock for subwoofers. Paired with an Android Stereo. For under $600 I got a bunch of sound.

Arrived very quickly, looks sleek and quality construction. Would buy this again

At this price, it’s hard to find a better deal. Install was straightforward, set it up on a 2-channel service, output back into the car’s speaker harness - the results are amazing.Soaring highs and crisp mids, with some simple customization dials to fine tune the sound.While this unit feels sturdy and expensive, my only fear is longevity… but time will tell! Very pleased a month out.

This Amp is really impressive for the price. I did a head to head (totally amateur) comparison of a few different amazon amps in the price range and this was the only one that didn't sound like garbage. In fact, I'm quite impressed with the sound quality. Is it anywhere close to the advertised output? Of course not! Don't expect to drive four 6x9s and a set of subs but if you're like me and running four small coaxial speakers and want something better than the head unit power, this is a really good choice in the sub-$100 range.

DO NOT BUY THIS AMP. It worked for about a week really well. Then it started cutting out at times. If I reset the amp it would work. After a few days it just stopped working. the power button was on but I couldn’t get any sound. I reinstalled my old 400 watt amp to make sure it wasn’t the head unit signal. Guess I’ll just have to use my old amp. I will retract this bad review if they would send me another amp to exchange and it works well

Sounds good, but when I installed it on my motorcycle, I get bad engine noise

Installed this in a 2019 Rav4 with GTO 629 speakers.Pros:Clear soundGood match for GTO629 6.5"Cons:Didn't auto sense turn on with hi-level inputs. Had to use 12v remote wire.Internally wired wrong. Left and right sides were backwards. 2 channel mode was 4 channel mode and vice versa.Got this hooked up and couldn't figure out why I wasn't getting sound to the rear speakers.
