Sooo if i want to put in new front door speakers on my 2008 335i w/ logic 7;
Do i need to change the head unit?
the speakers i wanna put are these focals 165krx2:
they are 100 wat rms tho - i think i heard stock door speaker amp is 4 x 40 ?
how does it work if i wanna change the front door speakers only? i get 2x 100 amp, is there a way to wire it so that it powers these 2 speakers and the rest stay on the stock amp ?
