Yeah, I've been through several sub setups with my car. When I just bought it, I listened to a ported JL 10w6v3 HO WEDGE enclosure. The store that I bought it from demo'd it for me in an Rx350. I was sitting in the RX and was surprised at the output. I bought it and installed it in my IS w/ a matching amp. it sounded good, but nothing like the RX - a lot of the bass was swallowed up in the trunk lol. I don't like pounding, booming bass, but I do appreciate a clean, full sound and it left something to be desired.

I figure that even if you try the sub on the factory amp, and find that it doesn't sound as good as the setup in the NX, you can always add a small amp later on. Adding an amp is a pretty painless process for our cars. So it's definitely worth a shot. Let us know what you decide to do once it warms up a little.

Another option may be to tap into the harness at the factory amp. This way, you won't have to disassemble the rear deck. The harness may be cramped, so it may be a little tough to squeeze in the wire taps. But where there's a will, there's a way lol

 

Since we are on the topic, is there a like for like drop-in sub replacement without adding an amp, that will somehow sound better than existing stock one? Obiously, a car audio noob here...

 

Member r2digital dropped in an Image Dynamics ID8v4 powered by a dedicated amp. It looked great - very clean install and he retained all of his trunk space. He said that it sounded better than the stock, but he ended up wanting more and replaced it with a sealed box. Perfecting the sound with those IB installs can be tough. I installed a shallow mount JL in my infiniti. Sounded good to me, but my rear deck rattled like no other, and this was after applying copious amounts of sound deadening material. Also, in addition to sealing off your trunk, you have to make sure that you've got a good seal between the cabin and the trunk or you may lose some sound quality.
