My friend has a Q-logic box which is sealed (.65cu) and he's looking for 10" sub and an amp for it. I suggested an elemental k series 10, and maybe a hifonics z4000. That amp is rated at 400 watts at 4ohms bridged, so he would want the dual 2ohm sub so he could run it in series correct? Does this sound like a good set-up for under 400 dollars? Any other suggestions? Also, he's got a 110 amp alternator so he should be good there right? Last edited by Slump_Da_Hustla at Oct 21 2002, 04:48 PM
