BLAUPUNKT AMP1804BT Car Audio 4-Channel Class D Amplifier 1600W with Bluetooth Full Range Amp.

Is really good for the price. Bluetooth connects perfectly every time. Never have an issue. Note this amplifier is not meant for subwoofers nor is it meant to supply a lot of bass. I see reviewers commenting on those 2 topics but as said it is not meant for deep bass this is meant for high or all pass for door speakers for quality sound. Super simple to install and setup if you know how to tune. Gain shouldn’t be any higher than half way unless you’re using a very old head unit. I’ve used this amp in multiple vehicles including motorcycles, ATV, golf carts and classic cars where the owner does not want to modify the factory audio. And it has worked for me flawlessly every time using Bluetooth or rca. Build quality is much better than I expected originally. Only supplies average 100w rms per channel but that’s perfect for most builds. This keeps it simple to have Bluetooth built in. I have found that the lil antenna does come loose so I’ve been using a drop or 2 of blue loctite and hand tighten seems to have fixed that issue. Bluetooth doesn’t reach too far but I’d say a good 10-15 feet which is plenty. Wattage rating are very overshot this is not near 1600watts that it claims. Dynoed at about 600 max and about 300w max rms bridged. Most door speakers can’t handle more than 60-75w rms so it’s not a deal breaker for me just a bit annoying that they advertise a lot more than it really is. But again for the price really can’t go wrong

Really impressed with this little unit so far! Just hooked it up in my teenager’s first car. Hand me down 2006 Corolla from his grandad. Didn’t want to throw a ton of money into a stereo system for the little old jalopy. Fun project to put new speakers and then run the stock unit through the amp. He will never use the radio, just run Bluetooth from his phone. Took a little wrangling to get it all wired properly. No real instruction included, but YouTube is our friend. The sound and power boost is really really good for what he needs. He is tickled pink! You need to disconnect Bluetooth from the phone to allow the original radio to pass through the amp, but once you figure it out it works pretty slick. I’m not tech savvy enough to know if it delivers exactly what it claims, but it sounds fantastic to us. Everything hidden away, so just looks like stock 16 year old system. Super happy so far, but it has just been a day!

Cumple con todo lo prometido

The Blaupunkt Amp 1804BT is actually pretty decent. I've been involved with car audio since 1986 and have used all manner of brands and have experienced the advancements in amplifier technology over the years. The 1804BT offers good power in an easy to install package. I used the RCA inputs for my initial testing. I wired the front channel speaker outputs in stereo with the crossover set to around 80hz to a pair of 100 watt rms per speaker pair of Polk Audio DB652s. I left the rear channels unused at this point. In this configuration the amp provides clean power with plenty of volume. The mids and highs were clear with no added noise from the amp. I then disconnected the front channels and wired the rear two channels in bridged configuration to a single 300 watt rms rated JL Audio 10W0V2 4 ohm 10 inch subwoofer with the crossover again set around 80hz. Honestly I didn't expect much out of the JL woofer with this amp but, I was pleasantly surprised. The bass was punchy when it needed to be and it got deep when it needed to. The final test with RCA's connected for me was running the amp with the Polk 6.5s on the front channels and the JL 10 bridged on the rear channels at the same time. In this mode the amp performed admirably. I ran it at high volume for at least 30 minutes and the amp stayed cool. I then kept the same speakers hooked up to the amp and used the amp's Bluetooth connection. It paired with my Android phone without any issues. I did however need to adjust the amp's gain controls when using the Bluetooth feature as it seemed to offer a more powerful signal to the amp versus my stereo's 5 volt RCA outputs did. My advice, just be sure to properly set your amp's gains no matter which input you use. This amp is compact. It will easily mount in an out of sight location. Just be sure it has proper ventilation.

Está bien justo por el precio q pagas , yo lo use para un auto pequeño (spark) 4 bocinas , de fácil instalación , lo uso con el celular todo el tiempo y sin problemas , no tiene gran potencia pero considero que es más que suficiente ya que ocupa Muy poco espacio.
