Pyle 2.1 Bluetooth Marine Amplifier Receiver-Waterproof 4 Channel Wireless Bridgeable Audio Amp for Stereo Speaker with 400 Watt Power Dual MOSFET Supply,GAIN Level and LED Indicator-PLMRA410BT, BLACK

Cubrió mis necesidades, lo instale en mi auto para definir e incrementar un poco más el sonido en 2 canales y resaltar bajos en otros dos, tiene la potencia y calidad de sonido que necesito.

I bought this for my pontoon boat because I got tired of always trying to tune in a radio station. It has plenty of power for four speakers and the bluetooth works great. Installation is fairly easy depending on the wiring in your boat. Mine has plenty of electronic features so it was a chore figuring out what power cable to use and then tying in to the speakers so I could still have the radio work as well. It does not include a remote start switch so I found it easier to run to Walmart and buy a waterproof on/off switch to add to my instrument cluster. Now I just tune my phone or tablet to Pandora, flip a switch and I have static free music. The unit is well built and I would recommend it for most cars or boats.

Arrived quickly and works perfectly - Happy with purchase

WOW! Incredible performance for such an affordable amp! Bluetooth feature pairs fast & works perfect with Samsung Galaxy S4/S5/S6 & Note 4 to approx. 30ft. from amp. Speaker line levels fairly quick to get dialed in. Installed in a Polaris ACE SxS with two 6.5" 200watt marine speakers & two 8" 400watt marine subs. Sound is so much clearer & the subs pump pretty good with this amp! Using with a good high power head unit will make all the difference in the sound quality. Make sure all wiring is large enough to get the best performance from the amp. Going to order another just for the subs!
