A:AnswerId say you going to need speaker adapters, unless you want to tap or splice into your factory wiring. You may need what your refering to as a spacer if you dont have enough room in the door.
A:AnswerI have a 2015 Dodge Challenger with the lowest stock speakers and these are an enormous improvement. When you remove the stock speakers and compare the weight of the stock versus the Kickers, the Kickers weigh twice as much. I'm assuming that means a larger magnet which will push more air and create a wider sound. These Kickers are so much clearer, the difference is night and day. Last thing, whoever made the stock speakers didn't even put their brand name on them; they must have been embarrassed.
A:AnswerYes it can ,it would take the same size speaker as a regular vehicle ,whether it’s a 6 x 9 or 6.5.. The difference is the area where it can fit.
A:AnswerThat's super cheap, I had an impala and did a rear speaker install myself. I'm pretty sure I had to pull my back seat out, to get the rear panel off where the speakers sit. $50 is a bargain.
