Blaupunkt 1500W 4-Channel, Full-Range Amplifier

I tested this using an oscilloscope, rock concert sound pressure, maybe even competition level, powering only my front speakers, absolutely no distortion at extremely high sound pressure/decibels, I am a certified electronics technician, fell in love with this amplifier, I'm also a metal head and an audiophile who loves metal core playing guitar and electronic dance music genres of many types, and I have to say it's reliable, efficient, effective, and loud enough that after getting permission from a local gas station in an area I made sure no local housing is located it was loud enough without distortion to crank the volume close to maximum with no distortion and I could hear the music across the street while standing on the sidewalk which is pretty far from my car, and that was running two 150 watt rms speakers, I plan on bridging and setting it up with 300 watt RMS speakers for holiday events and for events with friends because the sound is already extremely loud and the amplifier can actually go further powering 2 speakers, and so I'm recommending this literally to anyone wanting an extremely high quality amplifier because this amplifier is excellent, it's exactly what someone wants if they are looking to have some loud sound to enjoy with everyone. Extremely recommend, 5 stars I would give 10. I'm in love with this amplifier.

I barely have the gain at a 10th of the full gain volume, and with the speakers I have, the same ones it's rated for, it's very loud. Unless you're trying to break up a kidney stone or rupture an eardrum, this amp will do you right. This is plenty loud for me and my needs. As of now, it's installed and working great, but I will definitely update you if something changes.

I bought this amp for my car to do a budget sound system upgrade. So far it works great and everything about it is good. The only reason I didn’t give it a full 5 stars is that it is extremely underpowered compared to what it’s rated for. I was driving 4 x 45 watt speakers which according to the spec sheet should have been no issue. But I was getting a slight distortion right around the 13.4 volt mark which is the 45 watt spot so I had to turn it down to 13 volts which is fine for me but if you plan on driving any speaker over 45 watt 4 ohm I would pay a little bit more and get something a little bit higher quality. Also it was fairly large for its power output and just barely fit under the seat of my Subaru and other company’s make smaller amps that do the same thing. Once I got sound dialed in the quality was good though.

This Blaupunkt amp has wattage ratings far beyond it's actual output capabilities. Most amplifier Dyno videos document this.How much amplifier do you actually need and whatever you buy, it has to fit within your budget.This amplifier has build quality above and beyond Pyle and pyramid build quality and is pretty clean free of alternator whine and ground loop issues. It has most features anyone needs and is designed to be a high/full range amplifier. I don't think it would do subwoofers very well, but that's what mono block amplifiers are for. If your on a tight budget and want a quality amplifier for full range sound and don't require sound levels that will make your ears bleed, then this isn't nearly as bad of a deal as the amplifier Dyno guys say it is. No you can't connect welding leads to the speaker terminals and weld with it. But for the price point it does pretty well, depending on ones expectations. If your operating on a pyramid cash flow and need a good 4 channel amplifier for full range sound. Then step up to this and get a much cleaner and clear sound (not wide open volume), LoL.It will give you better than double the power obtainable from a quality 4 channel high powered head unit cleanly.I wish amplifier manufacturer's would rate wattage ratings more inline with the products capabilities, but this is an age old problem for decades, so don't be surprised when an amp won't come remotely close to it's wattage ratings. I guess if they rated it correctly no one would buy it in hope for a super product for very little money. Too good to be true; it usually isn't.In this case the amp isn't cheap shoddy build quality. Yes they could have added higher value capacitors, but it has enough to be clean sounding. The amplifier manufacturer's are not going to build a super superior product for all but nothing as they have to operate on price point as well.To me ask yourself how much amp and what you want to do with it to determine if this product is for you and within a given budget. If you want to power subs, then mono block amplifiers are the way to go.Hopefully I have cleared the air of controversy concerning this product. I'm happy with it and the price point as well.73 Earnest K5EWM 👍. It's a keeper.

I do not understand the negative reviews for this product - i have been running this amp since July of 2023, it is not Jan of 2025 - NOT A SINGLE ISSUE - daily driver avg 2.5 - 3HR in IL where temps swing from negatives in winter and +90 in summer - amp on all times, at 75% crank up to all channels - not running the HPF/LPF, adjusted at the head unit - not a single issue. The only logical deduction is that people that torch these out or fry-pop them installed them incorrectly or are completely electrically-challenged. If you know how to hook-up, set, run car amps - get this one! the price is too crazy low to pass this up and you will not regret it. to all the fry-cooks out there, get something more expensive that comes with a more juice than you need and has multi-safety features that will prevent burn outs. keep in mind your amp is pulling from your car power, you do not want to experience ANY kind of electrical issues with any amp as it can compound into a major car-electrical issue down the road, and to that point, frying out your car-electric-system on a $100 amp, is just silly.

Product received damaged, not working and branding has also peeled off. Nuts on connectors are rusty. Very disappointing. Money wasted!

Great size fits , volume adjustment great,easy to install,clarity ,so far durability.
