I want to upgrade my BOSE speakers.... Currently I have a Alpine CDA-7897 HU, with my stock BOSE. It's been fine so far, but the rear speakers have failed. I want to upgrade them, but don't want to break the bank. Here are the parts that I have chosen.

Amplifiers...

Highs: Alpine MRV-F340

Low: Alpine MRD-M500

Speakers...
MB Quart RCE 216 6.5" Components, for the front.

MB Quart RKC 116 coaxial spearkers for the rear deck.

Single Crossfire WD12, in a ported box.

Any opinios, comments?

Thank you.

 

good amps good speakers not sure about the sub

you can never go wrong with alpine stuff.

 

^^^^^^^^^^^^^^^

 

i would consider another sub, but if you like what you've heard from crossfire then stick with it good luck

ps otherwise i think everything sounds like wise decisions
