I was strongly considering getting an alpine HU but I dont like the Ipod Control that they have available for it, so my question is can I just use an aux input on most alpine models or only specific ones? and if so, what type of connection should I be looking for because I'm not sure that alpine uses rca connections as their aux out. Also if anyone could recommend other HU's at the $200 range that would be a better option but still have 3 pre's and an aux out. thanks in advance
