Nice install.
Everything looks a bit familiar, ill go out on a limb and say that door looks like it belongs to an 00-01 Maxima //content.invisioncic.com/y282845/emoticons/eyebrow.gif.fe2c18d8720fe8c7eaed347b21ea05a5.gif
Personally im running the Arc 2300SE to power mine (340ish rms X 2) and from what time ive had to play with them, I can say definitely go easy on the gains with 425 going to them.
Those mids will let you know the second you crank it up too loud, just trust me on that one //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif The hardest thing you'll run across is the mids playing too low on certain songs, basically the mids will reach their limit before the volume for the vocals are high enough. You'll just need to keep tuning them until you can find a fine balance, regardless they can get **** loud and the lowes they kick out is IMO lower then advertised.
Those tweeters are //content.invisioncic.com/y282845/emoticons/drool.gif.b5e863e893038027711d4402f340dad0.gif as well. Im sure you'll love those comps, just take your time getting them tuned in.
