First off, these are big. Just be aware. That being said, the quality is top notch. The bracket system (which Kicker really highlights) is awesome. Quick Connects I will utilize if I'm leaving the boat open and unattended. The extra bolts and hardware are also super apricated. Fit and finish very good. The speakers themselves, really really nice. I'm powering each with 300rms and the sound is really nicely balanced. I have not had a chance to water test them but on the trailer these things easily through the music and the larger size (kmtc11) really holds the bass over distance. Highly recommended.
Just installed them and I haven't installed the new amp yet but even with the under powered amp that I plugged into the sound is very good and very clear
