Mostly every thing is compat with everything, just got to get the right amp and the right channels. Never wanna under power speakers or subs because they will pop a bit faster. Always look at the ohms and the rms of the amp and speakers.
Some cars, come with premium sound, known as the bose system, how would I replace it to a non bose system to add a Different Head unit, new speakers, like polk audio. etc. From harness to finish please.
