Yamaha COMPLETE Audio upgrade Kit

The audio upgrade kit for my 2023 GP1800 svho installed in only 2.5 hours, and was super easy to do. The kit sounds perfect! Very well thought out and designed. I would order again.

Seems good but I follow all the instruction and cant make the left speaker work yet everything and the customer support was Quick to answer but Even with following all the instructionthey gave me the left speaker still dosent work probably a faulty unit so im stock with it for now without upgrade install sad for the Price

Product is as described. It 110% handsdown is higher quality and louder than factory. I shouldnt have a problem hearing music now on my 24 gp1800 SVHO. Only tough part was finding the best spot to bolt the ampilifier to. Other than that, its worth the money.
