Hi, I am starting a new install on my new boat. I have no desire at all of using an amp (due mainly to cost as well as battery usage during hours of sitting around fishing).
I have already ordered 2 pairs of Polk's MM651 (2.7ohm). I think I may have made a mistake there and should have gotten the MM651um (which are 4 ohm). I wish to run these speakers off a Fusion MS-RA205 http://www.fusionele...series/ms-ra205 which is rated at 50W x 4 (at 4 ohm).
I am now very worried I may blow something (I will turn the volume right up during skiing). And that I have to try and return the MM615 for the MM615um.
The retailer (other side of the country from me) assured me that it will be OK, but I am still worried! So should I go through the expense and hassle of swapping these for the 4 ohm speakers, or am I worrying about nothing? On another note, the speaker's box does say it is compatible with 4 ohm outputs.
