You *can* put in the L7 speakers, but you don't *have* to.
FWIW, I have the hi-fi system and just adding Technic's harness assembly and a JL XD 600/6 made a big difference. This coming from a guy who has Hybrid Audio Technology speakers in the E46M3 (and going into the X5 next week).
Install is a snap w/Technic's harness, power, and ground. High quality kit. You just need to mount the amp and that's relatively easy if you have some rudimentary skills.
