@3Dave I was looking for the small washers that go under the engine cover. I ended up calling an Infiniti dealer and they knew what I was talking about. They're like $10 a piece but since i only need one it's no big deal haha. Thank you for offering to help!

@tjwrona1992 Glad you found the parts. As far as stereo goes, $2k is a huge budget assuming you're not entering car show-level audio contests. Check out crutchfield.com.

... and when you find something there that you like, go look for the components on Amazon.

@3Dave I'll take a look thanks, I have been talking with a local guy who does custom audio and he was telling me that since the Bose system is a 2 ohm system I will need a new amp if I want to run 4 ohm speakers otherwise there will be a big drop in output. It also sounded like some additional DSP hardware may be needed to allow the system to be tuned to the new speakers to sound at its best. It seemed to get pretty pricey pretty quick (like 3-5 grand)

Although I didn't get the feeling like he was trying to talk me into buying more just to make more money. He seemed like a pretty honest guy.

The G37x also has a floating sub in the back which makes it sound really boomy but gives it a pretty loose bass response... I was hoping to also get a sub to tighten up the low end, but unless I want it taking up all of my trunk space I would need a custom enclosure which also adds a lot to the price. (I'm not exactly handy enough to build one myself lol)
