I have one blown out speaker. Want something with a little more power handling so it doesn't happen again. Thinking about the Polk Audio DB5251. They are marine rated and have great reviews. Just wondering if the stock radio will push enough power to them to sound decent and where some may have mounted the crossovers. I am assuming double sided tape to the outside of the speaker housings under the dash. I found some awesome double sided gel type tape that holds like a screw. Use it on my RC stuff so I know it can take the vibration.
