I'm getting my old car audio removed from my old B15 Sentra, and I have 6.5 inch JL XR 650Csi components. Will these fit the front door/tweeters? I would hope these speakers are better than the Bose speakers that come factory correct?

Also, concerning the Bose Amp, I have an Alpine V12 5 Channel Amp. Can I simply unplug the Bose Amp and plug this one in its place? Sorry for the newb questions, but want to know if I can use my stuff or do I need to sell it.

 

The XR are awsome and should fit fine and are a great speaker. If you are going to replace the amp then replace all the Bose speakers or the resistance will be all screwed up.

Do you hear me?

 

I'm just a little hesitant to change the audio in the car. I've had it a total of 4 days and I must admit the bose system doesn't sound as bad as everyone makes it out to be.. my thing is this:
From my Old Sentra I have:
1)Alpine 7864 HU (old model, was going to swap.. but oh well )
2)Alpine CHA-S634 MP3 CD Changer (I REALLY want to make this work in the G)
3)Alpine V12 5 channel amp
4)Alpine 10 inch enclosed bandpath box with Type S sub.
5)JL XR650 Csi

What would you recommend??
