A:Answer70 RMS a pair, I matched it with the kicker for channel bridgeable 300 series amplifier. Sounds great although they are mounted in a sealed set of component system boxes built for Kenworth’s for 6 1/2. Speaker system. Which are no bigger than bookshelf speakers.
A:AnswerThey should work with factory amp ,but may need a something else as for amp may not push the watt the speakers need,i have a set but their not in yet and mine are going in kick panel of old truck
A:AnswerIt should come with wires attached to the speakers that are probably long enough to reach the existing car speaker wires in the door of the vehicle. I bought adapter wires for my install.
A:AnswerIt can be used as a woofer alone, yes. You would just hook it up not using the crossover. Why not just use a coax if you aren’t going to utilize the separate tweeter from the component set?
A:AnswerYou'll need to measure the depth of the space for the speaker in your door or call Volvo to get that specification. And get the depth measurement of the speaker or get that info from Best Buy or the JBL website.
A:AnswerI don't believe so. The best thing to do is research on crutchfield and then start looking for speaker options. From what I can see, your speakers are 5.25in. I don't know if you can put a larger speaker in place since I've never done a Jeep before.
A:AnswerAdding a subwoofer would have very little (nothing) to do with these speakers. You would not connect the subwoofer to the crossover supplied with these. Once you add your sub, you would have to add an amp for the sub. That amp would have a filter that you would turn on (or the head unit may have a filter depending on what you have) that would send the low frequencies to your sub.
