## Description

Product description

Review: Works well when installed correctly - This is a great addition to my Jensen MSR3007 in a SeaDoo jet boat. I am not sure why many folks are getting poor quality or results, but if you know what you are doing, this unit works as advertized. I made up a pair of Molex connectors so that I can either insert or bypass the amplifier using the factory harness when not using the wake tower and wake tower speakers (Boss Marine MRWT69W 6x9" 4-way speakers), or when I do not want to consume more battery power while out on the water. I also replaced the original Jensen speakers in the boat with Boss Marine MR60W 6.5" 2-way speakers. I first tested the 4 speakers without the amp and thought that I would not need the amp because the sound was adequate. However, after testing with the amp, I changed my mind. The sound is very clear and _much louder than with the Jensen 3007 alone. I used the 4 low impedance inputs connected to the speaker outputs of the Jensen to maintain front/rear fader control and adjusted the gain in accordance with the installation instructions. Also added the Kinivo BT adapter for audio streaming and telephone calls from my Android cell phone. Finally, will be adding the wired MWR100 remote control for the Jensen unit on the swim platform very soon. Voila... a totally fantastic upgrade for the boat, all ordered through desertcart. I would recommend a professional installation if one is not 100% confident in their technical ability. I can also offer advice if anyone needs it via msouhlas@yahoo.com. Mark

### ⭐ now my new amp is costing me an extra $40 due to the waste on this amp
*by G***Y on August 20, 2016*

Hooked up on my boat, worked one time, my next trip out the fuse blew, bought new fuses and messed with it for several hours, reconnecting everything, ensuring proper setup, kept blowing fuses. This isn't my first amp, never had issues with other brands. Also the one time the amp worked, it didn't produce much power, I would say no where near the 400 it states...so one trip less than 400 amps, 2nd trip no Amps and no music. Wish I could return but it's been 40 days, I'm shocked it broke so fast, my gut told me to spend a little more and I wish I eould have, now my new amp is costing me an extra $40 due to the waste on this amp! Thanks Pyle, excellent quality....
