A:Answer You would have to get the measurement of the speakers in the vehicle to make sure that 6.5 inch speakers will fit. The speakers do have adapters with them to help them work with many 6.5 inch openings. And if you are planning on using an amp with jbl speakers, I would definitely recommend using a jbl amp. Depending on the amount of speakers you would want to hook up to the amp, would recommend using and amp from the jbl 4 channel amplifier line.
