I am currently running the Hertz Mille Series 6.5 components, and the Hertz MPX 6x9's with a JL Audio XD 600. For subs, I have 2 JL 12W7's each running with their own JL Slash 1000/1 amp (still finishing the new box build and install had to refoam 1 sub). My head unit is the Pioneer NEX 8200. This is in a Camaro 2011. I feel like the NEX 8200 has a lot of audio capabilities, but not sure if adding a DSP to the system is truly needed, to be honest I don't know a lot about DSP's. However I was considering the Audio Control DM 608? Thanks in advance for your input!
