Went there yesterday, and bought all my stereo gear (head unit, sub, amp, speakers). I can honestly say that MCS is the best company i have ever come across regarding ICE. The bloke i spoke to was extremely helpful, advised me really well on the exact bits to buy, and matched prices on the spot. The shop was really very well stocked, and the range of products they supply is fantastic.
I would reccommend them to anyone, and will be using them and them only in future!
