I would NOT recommend anyone buying from Ikon. I just bought 3 pieces from them. The rear bumper/diffuser (some big drip of something on it). The front chin was cracked in 2 spots, and the side skirts were formed incorrect.
You only use the Zen or Pac if you have the B&O. If you don't have the premium audio you can just feed the stock speaker wires (high level) into your DSP. I would suggest a Helix or Arc Audio DSP because they have an input EQ so u can flatten the frequency response.
That isn't included in any package. My dealership found a used one off of an S550 for $60 (mint condition), and installed it in 5 minutes. From Ford parts new they're like $550
The car already has a 190 amp alternator, so that's more than enough. I have the stock AGM battery and a Limitless Lithium stashed away in back. All zero gauge OFC
What amps are you using?
