Marine Amplifier Bluetooth Waterproof Multi-Function Remote Class D Amp ATV UTV Amp 4 Channel 500 High Output

I used this in a 1970 Chevelle. I hooked up four speakers to it and mounted the controller where radio used to be. The unit itself fit up under the dash perfectly. Even left the usb pigtail hanging out so I have a phone charger in the old car too. Sound is perfect and Bluetooth works awesome! Would definitely recommend for an old hot rod! Very economical, quick, and easy way to get some tunes going.

So I installed this on my Honda Goldwing GL1500 and the hardest part of the install was finding the wire diagram online. I will say that they could make the wiring longer and shorten the remote wire a bit but I was able to make it work. It sounds great and works well held up for the 1000 mile round trip with no issues.Here is a piece of advice for anyone wanting a Bluetooth amplifier for a GL1500, you may want a smaller 2 channel amp since the factory stereo is only 2 channels out. Now what makes the factory stereo a 4 channel system is the is the front, rear fader on the handle bar.

I wanted to like this amp. It has some nice features, particularly the low level output that most of these are missing to be able to hook up a powered subwoofer properly. However, its completely shuts down at about 40% volume when using only 2 channels into 4 ohm speakers rated at 170W. This is independent of the transmitting device (phone) volume. Even if the phones BT volume is set very low with little power out from the amp, it still shuts down at about the 40% volume mark. Seems to not be related to power output, but something else. I contacted the vendor and they insinuated there was something wrong with the wiring. There absolutely is not. Then no further response from them. It is definitely a defective unit.

Installed in a golf cart, can’t base the price

I did a teardown of the Audiozerone amplifier and discovered two TI TPA3116 chips inside. These chips can theoretically deliver 50W per channel at 26V, and when bridged at that voltage, they can push 100W x 2 channels. However, in a car setup with 4 ohms and 14.4V, they realistically output 22-26W per channel. According to TI specs, the amp chips should be 88% efficient at this voltage and resistance, putting it on par with a good aftermarket head unit.If you’re streaming from a phone directly to this amp on a UTV, trike, or bike, it would be a decent solution. However, if you have an aftermarket head unit and are using this amp to power your speakers, there is no benefit. If this unit is powering additional speakers along with those powered by the head unit, it would do okay. The listing claims various power outputs like 70W, 120W, and 500W, but technically, it falls between the lower values. This amplifier might need a follow-up from Mr. Dick Riculous off of Williston’s channel to determine its true capabilities. This is not a Mickey Mouse program!The unit is well-made with an aluminum center amplifier housing, while the end caps and mount flanges are plastic. It features a Molex harness-style speaker output and four RCA high-level inputs. The wiring is a bit odd, with a red trigger (remote wire in) and a blue remote wire out from the amp. I guess you can power on a mini mono sub amp when you turn on your mids and highs running on this amp. Overall, it sounds good but is on par with a head unit and doesn’t match the level of Clarion, Kenwood, Sony, and other CEA-compliant mini amps on the market. It’s a good option for some decent tunes on a budget!

This little amp has plenty of output for my RV the sound quality is quite impressive for an amp of this price

I liked that the Amp is easy install and bluetooth is quick connecting and USB is good to but they say it is loud only at low speed at 70 to 80 mph u can barely here the music so when they say it has a lot of power yeah at low speed won't buy again

put it on a golf cart. Works and sounds great.
