So I recently purchased a 370z, which has a tiny trunk space. I was planning on buying a custom box built for the 370z, but I have no idea where to start when it comes to picking out subs. I was planning on having 12s, not really sure if I should have one or two. I just want a quality bass that bumps. I want to be able for people to think "**** his car bumps." I also would need an amp to go with it, which I also know nothing about. Not looking to spend more than $300 on the sub(s) and amp. I just need some recommendations. Please help.
