Looking to upgrade the speakers and amp's in my e93. The stock system is just not cutting it anymore. I have the professional hifi system with iDrive. Just wanted your thoughts on the following set up:
1 x JL Audio XD700/5 - http://caraudiosecurity.com/shop/pro..._id/14888.html
2 x Earthquake 8" Woofers -
2 x JL Audio C3-525 5.25" Components ( Front & Coaxial for Rear )
Wanted to know if you guys know of any further cables, harness i should be aware of?
