JBL MS-8 ( read you needed it if you have NAV headunit)
Alpine SPR-60C ( for front only , diconnecting the rear speakers)
Alpine alpine PDX-F6 amp ( for front speakers/tweeters and subwoofer)
Alpine Subwoofer SWR-1223D ( i didnt know if to get this one of the 4 ohm one)

2.i am planning to run the speakers/tweeters and sub of that amp is that ok and keep in my i wont have rear speakers so its only 3 channels?

3. is there anything i am missing?

4. Thanks for the help

1. Yes it will work you just have to tap into the bose wiring for your MS8. "contact JBL if you need wiring diagrams and what wires to use"

2. You can only run amps in 3 channels if they support it. That one, yes you can.

3. Power wire, rcas, maybe dynomat?

5. Your welcome
