Hi guys im looking to buy some waterproof outdoor speakers that can connect to a normal hi-fi, max price i want to spend is about £70. they will be installed into the wood gazeebo roof above hottub , they need to be quite loud as the water from tub is quite loud i have came across these , will they work with normal hi-fi ? and do they look good value for money? http://cgi.ebay.co.uk/BOSS-MARINE-6x9%22-300W-WATERPROOF-OUTDOORS-BOAT-SPEAKERS_W0QQitemZ230345890515QQcmdZViewItem thanks for any help edit: i have no idea about speakers btw :P
