What's up everyone. Someone told me to go see Devin @ Audio Advice which is what I did. They want to put the following in my 2007 G35:
2 12" Arc Audio subs
1 600.1 Arc Audio amplifier for the subs
All new components (I don't know what brand, but I'm sure they are good)
Arc Audio amp for the components
Good quality box for the 12"s
Installation, wiring, crossovers, sound deadning, etc etc for $2,200 total.

I needed to research on the Arc Audio brand since I never heard of them, but after research I've come to believe it's a good brand...so what do you guys think of the price? $425 was for installation/labor.

 

That seems pretty good to me. I'm doing mine myself and I'm looking at about $2000 with all JL components.

 

arc audio is good stuff for sure see if you are getting hte ARC line of stuff or the lower KAR lineo f stuff? also depends on the speaker they get you of course...

overall, for a good shop that price is definetly fair 425 for labor to install evedrthing, i assume its just a normal box?) is not bad... i usually can do a little more with 2200ish but tahts a nother story...

go for it!
