Yes Martin I have them. I agree they do look a bit clunky but on a bike the size of the Rocket they don't look too bad. For there size and price I think they are worth it. In the 2005 Hein Gericke catalogue the description is as follows
01-02 HG Mounted Speaker Set with Amp.
Weatherproof speakers with 2 x 15w output, which is controlled by a compact amplifier. ( L x W x H: 75 x 52 x 25mm )
2 speakers inc. cable and connector, 1 amplifier, 1 connecting cable between personal stereo and amp, 1 live wire between amp and battery, 1 amplifier bracket with handlebar clamp.
01 Mounted speakers, black order no. 27008000 £34.99
02 Mounted speakers, chromed order no. 27008001 £45.99
Hope this helps.
I stuck these on cos I can't hear the bloody exhaust anyway (till I buy some decent silencers) and thought I might as well listen to something.
Wind noise is not too much of a problem as I have a large screen.
Rockt3, if you can here yours clearly at 100mph please let me know what you have.
Cheers hope this helps. Cooperman
