And I would still like to add a DSP to that possibly a MS8 or that rockford one idk..

I'm feeling like my X5 will need basically the same thing and darn I just dropped like $2k on all that in the M3 and I'm not going to say I'm broke but redoing these BMW stereos is like an all or nothing situation replacing the factory amps you might as well just run amps and that's a lot of money for me to drop right now..
So that's not going to happen soon..
