I have a pontoon boat, and I am trying to put a stereo in it. And I was thinking about instead of going with a marine 6 1/2" going with a pair of bose 151 outdoor speakers(older model not the se). The price isnt to bad comparitively and the sound quality out of the fully enclosed 151s is alot better. I am worried about ohms and maybe wattage compared to a house stereo. Will it sound close to as well using a car stereo? I dont want to use an amp and those speakers say rated for 40 watts I believe. which doesnt sound like much for a car stereo, but a house stereo 40 watts may be considered more. Any experts on the subject with an opinion appreciated.. tia
Your car stereo it rated at 4 ohms nominal, it is likely, and unless I am mistaken, many Bose speakers are rated as 4-8 Ohms nominal (Bose never seems to give complete specs). My guess is that the speakers operate at 6 Ohms, and therefore your car stereo will be delivering less power to them than an equivilent 4 ohm speaker. I have no doubt that the speakers can be used, my only concern would be that, as most decks really make around 10-15 watts RMS, the 151's are going to be underpowered for the noisy boat environment. I would suggest finding an inexpensive amplifier capable of 50 or so watts a channel to complement the speakers.
