3 ohm amp non sub

This is my first post, so please be gentile. I have a boat that I just bought tower speakers for. The specific speakers are Skylon Rubicon 450's.

I have a pair of these. Anyway, there are three speakers and one connector for these. I have recently found out that each of these are 3ohm's. I bought a couple of Kenwood 7252 amplifiers. The spec's on the speakers are - 450W/channel RMS, 550W/channel peak power handling. The amplifier spec's are 500 watts RMS x 1 bridged output at 4 ohms (4-ohm stable in bridged mode) or 170 watts RMS x 2 at 4 ohms (250 watts x 2 at 2 ohms).

The plan was to run one set of speakers off of one amp and the other set off the other amp. I planned on running the amps 500 x 1 @ 4ohms. What could happen to the amp/speakers?

My next question is, if something bad will happen to the amps/speakers, what amp should I go with? I think these speakers are full range, so a sub amp probably won't work very well (cut most of the upper freq's). Thanks in advance.

The speaker component's impedance is likely to be very close to 4 ohms rather than 3.  Speakers are generally built to be used with commonly available amplifers.  As you said, since these are full range components that include a tweeter, they wouldn't be intended for use with class D amplification.  Try bridging to the Kenwood amp.  Nothing bad would happen to the speakers if the impedance is too low for the amp.  As for the amp, if it can't handle the increase in current at that impedance, it will click off into protection mode.  You already have the amps so give it a go and see if it works.  Output rating of amplifier vs. continuous power handling of components is a good match.

Not sure how the speakers are wired. They are sealed, and the manufacture won't let anyone know. Wish I could change it. I will try it with the amps I have. Any input on what other amps out there that would be better suited for the application? Thanks
