there's this place called 'echo sound' in the al rayyan area. i'm afraid i can not remember the exact location because i only went there once when i bought mine. but a simple google search should get you the exact co-ordinates hopefully. best of luck. whatever you do, do not buy or get your stereo installed from the shops near the crazy signal. massively overpriced and incompetent technicians. you could also buy your stereo really cheap from the electronics section of dept stores like lulu etc and get them installed elsewhere. for example, the same stereo sells like 200 rials cheaper in lulu than the shops on the crazy signal
