I need some advice and would appreciate comments on how efficient you think my setup will be as I want a single 15 in the back of 335i bmw. The setup will either consist of a Hifonics brz2100.0 or most likely the 2400.1. And a single DD 9515 or Cadence Daytona (Unless someone knows something more efficent). Please let me know how efficient these sub woofers are as well as these amps also any other recomendations ???
My question is which Amp Sub combo is really effiecent and over 1000w rms I am not looking to modify my alternator or anything like that. I dont think these amps would over power them as they push 1.1700 and 1.1400 rims when wired down to 2 ohms....any other recommendations for amp/sub combo ?
btw whats the difference between these 2 subs from cadense in terms of quality sensitivity and frequency response ?
