Blaupunkt AMP1704P 1700Watts AB Class Full Range-Full 4-Channel Amplifier

Highly recommended! Please read this review carefully as it contains essential information that other reviews miss. I initially thought about giving this a 1-star rating due to some difficulties, but I believe that with the right setup, this can be a 5-star product, especially considering its price.I was searching for an affordable, high-quality 4-channel amplifier to power two front speakers and a subwoofer. My past experience with Blaupunkt was great, so I had high hopes. However, the setup process was a bit of a nightmare. I did eventually get it to work, but it's not straightforward.The watts per channel seemed a bit underpowered at first, but it does work properly when you take some extra steps using Y splitters. Surprisingly, even when sharing channels in mono mode, the sound is amazing.This amp is primarily illustrated in the manual to be used for either 2-4 speakers or 1-2 subwoofers, but the manual lacks crucial information on how you can combine speakers and subs. It was completely unknown on how it could handle both speakers and a subwoofer, but with my first attempt I managed to make it half work by combining my front speakers into the same channel and the sub on a separate channel. It's not ideal, but it sounds great even though they were underpowered using only the two channel switch. Thankfully I learned how to do it properly on the second attempt with RCA Y Splitters and using it with the 4 channel switch.The lack of channels can make it challenging if you want to power speakers and a subwoofer, and the manual doesn't clarify this. I spent hours/days experimenting with different setups, and eventually, we found a solution. It requires getting two Y Splitters female to two males, switching to 4-channel, and then connecting the sub to the bottom row (channel B) on terminals 1 and 3 and the speakers to the top row (channel A) using terminals 1 and 2 for the right speakers and 2 and 3 for the left speakers. Eureka!Before finally getting the correct layout it was still unclear if my setup was bridged or underpowered, the sound quality was at that point still excellent with minimal static.Let it be known that adjusting settings like HFP, LFP, and GAIN is crucial.Support from Blaupunkt is virtually nonexistent, and the manual is lacking unless you're using it for regular speakers only or subs only. Unfortunately, there are no comprehensive online reviews of this product so here is my contribution because it’s an amazing amplifier especially for the price.In conclusion, it delivers excellent sound and volume for the price, but it could have been more user-friendly. As mentioned I've successfully used RCA Y splitters to merge the inputs from the head unit into all four inputs on the amplifier, which significantly improved performance. It's a great product with excellent value if you follow my detailed review. Good luck!

Not bad. It works, puts a little extra into the speakers.

Good product nice looking item cool blue logo with a blue light easy to InstallAnd Powerful

This amp worked for about 9 months but never worked well. Turning the power up above half it would start cutting out like I wouldn’t push enough power. Now it turns on but doesn’t put any power to my subs.

Si buscas un amplificador varato y que se oiga bien este es lo que buscas no esperes algo impresionante pero si buscas algo que se oiga bien a comparación del audio original yo lo estoy usando en una cargo van y se oye muy bien es lo que yo buscaba tiene más tres B Bueno Bonito y barato

hooked up to replace planted audio 1000.2. this things is a light weight contender in the world of amp. unless your powering extremely efficient small speakers you need to pass. Too many amps here to buy that are way better in terms of actual power for speakers.

Great amp!! Performs better than expected. Except the RCA inputs are so poorly made that they break off after a while. Other than that, it's a great buy.

Added my JBL speakers and definitely push out the power and gave me exactly the performance I needed. Highly recommended and the price worth it
