I tried to search but couldnt find a specific answer. I apologize if I missed something. Anyhow, I am going to upgrade the speakers in my 2013 JKU with base system + connectivity. Was thinking about Alpine SPR-60C for the fronts and tweeters + SPR-60 for the soundbar. Also, MRX-F35 for the amp. Do I need to order anything else for the install? I would like to do it myself, but am a newb on car audio. The cost from the local car stereo shop is $1350 and includes install when I can order these speakers and amp for $450 online. Any help on what else I may need is greatly appreciated!
