I just joined this community hoping that the collective wisdom of the car stereo experts can help me with my boat stereo system. I have a 27 foot, 1979 sailboat that came with a Realistic STA-7M am/fm stereo receiver driving a pair of Realistic Minimus-11 speakers. The receiver and speakers are mounted inside the sailboat cabin and the sound is fantastic....lots of bass from the fiberglass hull resonating in a small space. However, the speakers cannot be heard outside in the cockpit unless they are cranked up real loud!
I want to mount external speakers in the cockpit area with a selector switch, inside speakers or outside speakers, but not both, at the same time. Question is what specification speakers do I need for the outside speakers? Speakers must have their own box or I can build a box(s) for them. I can't / wont cut a 6" hole in the boat to mount speakers. And they must be waterproof / all weather.
My MP3 connects directly to the reciever through the AUX input so I am looking forward to tunes in the cockpit while sailing. Current musinc library is diverse.... Beatles, Sea Shanties, Jimmy Buffett, Beach Boys, Classical, Jazz and traditional folk / blue grass. And I don't intend to blow away the dock rats in the marina.... just enjoy music while sailing at five knots.
Specs for the STA-7M are: "Audio Output Power at no more than 1% Total Harmonic Distortion into 4 ohms, over the audio spectrum, 20 to 20,000 Hz...... 10 watts RMS (minimum RMS power, both channels driven). Frequency Response (AUX input at 1 watt): 15-30,000 Hz
Minimus-11 speakers are 50 watts (music power maximum), 8 ohms and Frequency Response of 50-20,000 Hz.
Any help you can provide in selecting new speakers would be greatly appreciated.
