Answer 1

JL 1000/1.no disapointment here..

Answer 2

We are under the assumption you have the amp wired bridged mono, hopefully.  (L+ / R-)

Sub should at least move decently.  If you have an L5, you're powering at 2/3 RMS.  If it's an L7, you're powering it at about 53% RMS.  Both are acceptable ranges.  If you have it wired bridged mono, something else is not right.

Answer 3

is it a l7 or a l5, theres a differnce of 150 w rms, the l5 is 600w and the l7 is 750w. find an amp that has as close as possible rms ratting to match the speaker.
