Upgrading
 

New member, and thank you for letting me come and learn more about this hobby. currently have 07 Cadillac DTS with Memphis components in the front with 6.5 pioneer in the rear. Mmats amps power them along with a MMats 600.1 powering a single 12in DD Audio 112 sub.

I am currently in the process of upgrading everything. I want to add another 12, install a processor (not sure what kind), and last either a alpine halo 9 or 11 or the Pioneer wc 6600nex or something of those similar too.

With the signal processor, there are ones for both factory head-units as well as aftermarket? And lastly when you get a certain brand of processor do you have to match the brand of amp with it?

thanks
