Got an Alpine CDA-7893R head unit which pumps out 60W so all sounds quite good. The amps a digital monoblock 600W Alpine (one of the new ones) with a 10" Alpine dual-voicecoil sub.
Just gotta wire up the amp so all the talk on here about grommet holes is coming in very useful! Managed to get the stalk control think working at last; Cost me £60 extra for the bits but had to do it; some of the buttons have swapped functions. Apparently you can move pins around to customise it but Im not sure I can be arsed to take the dash out again!
