Hello all, I have a 1999 GMC Yukon that I use on weekends to travel to sporting clays shoots. This truck will never be used in a Audio competition just two semi deaf old guys(36 an 38) like to play it loud. The current system is: Subwoofers and speakers 1 JL 18w3 2 Jl 10w0s 4 Infinity 6.5s Amps Kenwood 9104D (powering the 18) Alpine MRP-M500 (powering the 10s) Alpine MRP-F300 (powering the 6.5s) Other Two batteries high output alternator "big 3" This "system" does okay but we are getting a little bored with it. I have a second Kenwood 9104d (900 watt rms at 2ohm limited to 900watt at 1ohm from what little research I have done these amps really do around 700 watts.) I would like to use both Kenwood amps to drive a pair of FI 18s. I have 24X24X48 to play with for an enclosure. What Fi subs with what options do you guys recommend for my set up? Thanks in advance Lance
