lol, well thts wat the forums for
rite on some cars there already is a hole from your bulkhead (under ur bonnet) to your dash. this is where you have to put the power cable thru from the battery to the amp, simple stuff, if there isnt a hole there you just drill one to get thru. you just have to figure would be a good place to put a hole, take the glove box out and you shud be able to get aces that way
sort of for the speakers, usually they are just spade connectors that slide on and off, you should get new connections with your speakers, if not just go 2 any audio place and ask for some
but if its stil the standard speaker then it is all part of the one sealed unit so you will probably have to buy adapters as well which screw on to were the original speaker was and leave you the proper holes to screw your new speakers to then you just join the connectors again
