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.
That's what I originally heard ok well thank you ill def try that first and see. By a big difference you mean? Better clarity? More bass? I'm decent with my hands just worried on hooking the amp up I have 0 skills in replacing an amp. Is there another way of contacting technic? I pmed him a few days ago no response.
