Hey guys,

Not Ford related. I am looking to fit a small system to my 2012 Mazda 3. not wanting to go nuts like I have in the past (getting old, I know). It currently has the ghetto spec (non-bose) system. While it is quite simple to replace, I plan on keeping the factory head unit, mainly for aesthetics.

Looking to add a small amp, replacing all speakers and adding a slim sub. The Amp that I am looking at (leaning towards the Alpine {DESCRIPTION}) has speaker inputs. Should I just use the speaker inputs, or still run through a signal processor?
I have acquired a {DESCRIPTION} because the price is right. What would the benefits be of actually installing it?

hey so i had the same issue as you with my ba i wanted the factory head unit to stay and i even have the same amp as you

with me i found it much easier to just use the speaker level inputs because it avoids having a middle man (the converter ) so if anything goes wrong you know its the amp or head unit no other trouble shooting ! plus it was designed to compromise for low powered head units and basically does the same thing as a converter !

so in my oppinion just connect the amp with the speaker wires
