I bought these as a replacement for three that I didn’t properly break in and blew as a result of my negligence. The first set rocked so I already know they are awesome. My previous setup in my 2008 RX350 was a 2500 way skv2 on 3 12 inch SVR’s. I had I lt paired with the stock system using an audio control LC2 pro. This time I’ll use a DS18 DDX6.9 head unit paired to the same bass setup and I will replace my front door speakers with the SPX 65c and I will use the tweeters from the package in my door pillars. I’m putting TX35’s in the dash and powering them with the stereo for now. So the LC2 pro is unnecessary I’ll remove it. And this setup should rock as well.
