I'm finally updating my Bose system as here is what I had in mind.

250/1 JL Audio Amp
XR650-CSi JL Audio Components
300/4 JL Audio Amp
JL 10" W3v2 in stock location

Any suggestions? Comments?

Question, if I'm going to put coaxials in the rear, do they require power? Or should I just do the components up front with the JL Audio 300/2?

 

well, I put the best components money can buy (for the most part) in my car. It sounds like ***** if you don't replace the Headunit. So with that in mind, you can use the 300/2 to power the front speakersn and use the built in amp from an alpine 7894 to power your rear fill. Voila!

I have to agree with Gish...the system will only be as good as thge weakest link, and your Bose head unit is pretty damn weak ! You will not get much out of your investement in nice equipment, unless you upgrade your head unit too...I tried every way possible to keep the stock look, but it sounded horrible, so I upgraded, and the sound is very nice now.
