The amp is in now, and sounds good. I was a bit worried when I put the new headunit in as I didn't like the sound it gave out, no matter what I did with the equalizer thingamy. It just didn't sound as good as my old Kenwood. Now I've got the amp in it's not all that important any more and it sounds much better. Only thing is, the wiring kit barely had enough cable for two speakers, let alone 4. Also need another cable to run from the headunit to the amp to power the rear two speakers, as I didn't realise they were separate.
