Well, if you fancy a setup like mine, its very cheap and works great.
Cabinate desceetly hidden in spare bedroom, that houses, a couple of amps, a cd/mp3/radio head unit, one that has IR remote control.
All speakers in cielings, a special waterproof one for the bathroom.
All this stuff is low voltage, as its design for a car... YES that right a car stereo wired up as a house entertainment system.
The IR remote wires were extended out to each speaker location.
It works a treat, great sound, music in every room, 5 rooms, IR remote controlled. total cost was less than 150 quids.....
