BLAUPUNKT 1500W 4-Channel Full-Range Amplifier

**Updated: 21 AUG 2025** So my better judgment won and I ended up returning my original first amp order due to the issue I covered in my original review (as seen below this update). First props goes out to Amazon for having a streamlined process for returning items for someone who next to never returns items. Very easy to figure out. Second props goes out to the seller for giving a no-hassle exchange. Very much appreciated! One thing I failed to mention in my original review was that the first amp was delivered in just a regular plastic shipping bag with the amp box inside, of course. Now that might not have been an issue with shipping, provided the amp manufacturer (in this case, Blaupunkt) had the amp surrounded by shock absorbing packaging. But no, the amp just sits in an empty cardboard box - in a clear plastic bag, wrapped in cardboard that sits inside the actual cardboard amp box. Given that, the amp itself - even though it's wrapped in a single piece of cardboard - the amp can still move from side to side within the outer amp box. That right there is a recipe for disaster. So I place no fault on the seller for this because as far as I know, they were probably like me and just assumed the manufacturer took the appropriate steps by placing the amp in some form of foam or other shock absorbing material. All that being said, that fact alone could have very well been what caused the amp to malfunction on that one channel during its time in the hands of the shipping company. Thankfully, the seller sent my new replacement in a separate box that had shock absorbing material. Thank you very much! It all worked out in the end as my replacement amp works beautifully, and I am so happy that I exchanged the faulty amp for a fully functional 4 channel amp. It sounds way better having the same output on all speakers this amp powers. Thus, my 3 star rating has improved to a solid 5 star. Woot-woooot! Given that my first experience with this brand of amp started a little iffy and had me questioning my decision making skills, I am super happy with it and I invite everyone who is interested in a high power 4 channel amp to give this a try. Whether you have the same experience or get lucky on the first attempt, you will be glad you did. Happy listening! **Original review below** I was so excited to get this amp for my front component Alpine Type R's and rear coaxial speakers. So much so that I spent a total of 12 hours installing the amp kit, speaker wires, RCA's, and all the good stuff associated with an amp install. Once I had all the wiring done, I moved on to figuring out where to mount this. In the end, and after lots of head scratching, I decided to mount it on my rear hatchback driver side wall. It was a bit tricky, but I now have what looks like a floating amp, and it looks sick! After the amp install, it was time for the awesome part of hooking up all the wires to the amp terminals. Badda-bing-badda-boom, piece of cake. Okay, that was the second most awesome part. The number one awesome part was the test and tune stage. Only, it wasn't so awesome after all. And this is where I feel that I got punkt. During my testing phase, I heard what sounded like blown speakers coming from my front right components. This can't be. I have been using all my current speakers running off my aftermarket head unit for a decade with zero problems. So off to the races I went with trying to diagnose the issue. All of my speaker wire connections are soldered, and all other cables are secured in non-pinch areas as well as having speaker/rca wires running down one side of the car and the power wire from the battery on the other side of the car. So there is no interference on that front. I swapped each and every speaker wire, and even went as far as testing both sets of RCA cables one end at a time, only to discover that one channel is bad on the amp. I know its the amp channel because no matter what speaker I connect to that terminal, including testing each individual RCA plug, the distortion is present. Total and utter bummer after all the planning and preparation to get this up and running. Now, if I were a novice at doing this, I wouldn't feel confident in my diagnosis. But being that I spent 12 years of my life in a professional setting installing and testing car audio applications on top of being a DIY'er in the car audio field for the past 29 years, I am very confident in my diagnosis that I was sent a defective unit. Which happens, but sucks because I really wanted this to work out for my system the first time. Another odd thing about this amp is that no matter if I have the selector switch set to 2 channel or 4 channel, I get sound out of every speaker. It is beyond strange that that occurs. I tested the full and hpf settings and the distortion seems to be more pronounced on full, and not so noticeable on hpf, but it's still present. So currently, I have my fronts on full and rears on hpf. Being that it is a 4 channel amp, I decided to wire the rear speakers to the 2 channels that has the bad channel since those are primarily for ambient sounds (which I always have the fader set more to the fronts) so that the distortion isn't very noticeable in this application. I'm currently debating on whether or not to just leave it as is considering that my road tests have me feeling positive about how it sounds overall. But then, it all boils down to principal. I ordered and paid for a 4 channel amp yet, I technically received a 3 channel amp disguised as a 4 channel amp. Decisions, decisions... But, I know me. In the end, it will be returned for a new one that hopefully has 4 working channels. I wish you better luck!

Excelente opción para amplificar tu medios y/o subwoofer, lo tengo conectado para 2 medios rango Xion x6m6 de 200w rms y tweeters tipo bala od diseigns y los amplifica a la perfección sin calentarse el equipo ni emitir distorsión, la mejor opción.

The previous Amorim has in was getting a bad altenator interference and clipping, audio quality is great and no more interference, lots of power and easy to setup!!

Buen producto,me llegó rápido y es de buena calidad,ampliamente recomnedable

If you're a regular person this is the amp for you. Inexpensive, easy to install and is nice and loud. If you're serious about car audio you should look at something with more options. Don't forget to do a little research on connecting speakers in series or parallel.
