HAve to agree with Stuart - a mate has one on his new BWM with 150 etec on it . I was going to get one, but its the wrong size for the 'hole' I have. I went with std sony marine unit & IPOD seperate in, I then have the snoy remot on the panel , but I cant control the IPOD form that - I just send the kids/ wife to the cabin to skip tracks, or mute it for a few mins & see what comes up next ! (there are something like 20,000 songs on my ipod - most of which rank close to Britney S , if not worse ! ) I do aim to play something like the dam busters as I race up the river at 4knts ! . The Jaws them with new 'ribbers' on the boat works well to !

I ended up getting the Poly Planar amplifier and a cheap 4GB Mp3 player/radio. It works fine and is loud enough to be clearly heard at full chat on the motor.
Its certainly better than listening to the missus singing ABBA tunes out loud

Anybody had problems with the Poly Planar amplifier?
Mine seems to stop working every now and again, be crackly sometimes and there is a slight whiff of burning insulation every now and again.
I have only had one day so far out of the three days out since I fitted it where it worked properly.
It is wired and fused to the manufacturers instructions and I just tried it again tonight. Very crackly for a minute or two, then fine and when switched off the smell was there again, very faint.
It is a bit of a job getting to it so don't want to keep taking it in and out until I know whats wrong.

Is the impedance of the speakers that are connected suitable for the amp ? and if so could there be a fault with one of them , like its gone closed circuit or something ? Sounds like a thermal cut out is getting activated

Speakers are as supplied with the kit. I agree its the amplifier but was wondering if anybody had problems with these before or I have managed to find a brand new fault!

Its not inconceivable that one of the speakers has gone duff if they've been poorly manufactured though, since they are the driven load, I'd haul them out and check them first, or just disconnect them and run the amp again without a load and see what it does

I ended up only getting round to looking at this last night, its not been the best of weather for working outside these last few weeks.
I ended up just buying a new set of marine speakers to swop over and when I took out the old ones found one with a dead short. Hopefully this should be the problem and when the new ones are in it should be all OK.
I am having to wait for a second replacment set though as I just assumed all "marine" speakers were anti-magnetic, it seems they are not!
A second new pair of Clarions on the way while the other replacement Boss's are on the way back along with the original Poly Planars as defective.
In the weather up here recently the only use I am getting from the boat is listening to the MP3 player under the boat cover so it needs fixing!

A short between one of the inputs and the speaker frame/chassis do you mean ?

Nope, across the speaker inputs. One speaker shows 4 ohms and the other 0 ohms resistance.
I am aware that the 4 ohms rating on speakers is impedance rather than resistance but one of them is obviously wrong!
I should have the new Clarions before the weekend and if it all works then thats what it was...

So its driving a short then, that explains the thermal cutout. Sometimes if the speaker cone is not centered perfectly the coil rubs on the magnet or chassis stripping all the insulating laquer off the coil, then current can leak or short across large sections of coil thereby almost giving closed circuit in extreme cases But if it wasnt defective manufacture that caused it, the other reason is, if the speaker gets constantly 'overdriven' beyond its capacity. In this scenario the coil heats up a lot, and expands, and the laquer burns and its insulating efficacy dissapears, together with the coil expansion, you are back to the same scenario as above, but you can usually hear this before total failure takes place, as the cone will sound 'buzzy'. Any chance of warranty ?
