View Here : Bose Car Subwoofers
To summarize, the car will receive the new speakers mentioned above plus a new sub and amp. The only stock parts remaining will be the head unit, 3 external amps, and 9" door speakers with the weird 0.5 Ohm impedance thing going on.
19) My car did not come with the original Bose car audio sound system, can I add it? 20) My Bose speaker is blown, can I replace it with any other speaker? 21) I have poor car radio reception, is it the radio or the antenna?
