I was talking to a guy briefly at the launch ramp and he said he runs a Boston Acoustic 1 ohm amp for his 4 tower speakers and 1 ohm is the way to go. What do you think? If I go 1 ohm, which brand?

1 ohm is not the way to go...and anyone will say anything to impress the guy next to him :D <BR> <BR>lower impedance means amp is flowing more current and is creating more heat so it is not the best for the amp. He may be running it at 1 ohm to get more power from it, but a more powerful amp running at 4 ohms, running cooler would be a better way to go.

does ba make a 1 ohm full range amp ? <BR> <BR>i dont know for sure, but i seriously doubt it...

i'm no expert but i think the only amps for car/boat audio that are run at 1 ohm are amps for subwoofers,

I have seen half ohm stable amps....the Hifonics Ulysses was a 1/2 ohm stable. <BR>It would put you in a 50 watt class for competition but in reality you would be running 200x2 at a .5 ohm.

there arent too many 1/2 ohm "cheater" amps around... the lowest you would ever want to go is 2 ohms...

Assuming each speaker is 4 ohm there are lots of options, setting it up to run on a 1 ohm load is pretty far down on my list. <BR> <BR>There are plenty of good four channel amps, a few big two channel amps that push 2 ohms/channel, you can mix and match series speakers and bridged amps if you want to save on tower wiring too. <BR> <BR>Running 1 ohm with our somewhat low boat battery voltages causes most amps to run quite hot and inefficient.
