I have been looking for a head unit and really like the CDA-9835 but I am looking for some opinions on it before I buy. Anything bad about it that I should know, complaints from owners? Is the display worth the money over the lower model? Also I have read that because of the amp in it you have to wire it differently, is this true? I will be using it's internal amp. Can you not wire it as you would any other head unit? Thanks for the input!
