Review on 🔊 DTI DS77MR Marine Speaker: 7.7-Inch 240W Max Power, Water Resistant Stereo Audio System (White) by Josh Koa

Installed them in the back of my boat so we can listen to music while we swim in the water. They've been on about six or seven picnics at the moment and have been braving the elements and the lapping of the LAKE water has stopped well. The sound reproduction is very good. I am using a SONY marine stereo with a SONY marine 400W amplifier. The stereo system originally installed on my boat had six (6) speakers connected to a SONY marine stereo system and it could not be driven at higher volume levels. I added these two to make eight (8); However, I have hooked up a push button switch system that only allows me to drive four (4) speakers at a time. Now with these and the original six (6) I can only run four at a time, the high volume problem was fixed. I highly recommend these speakers.
