the video you saw had 2 10" SVC running at 2 ohms on a jbl600.1 in a 1.0cuft per sub sealed box at volume 40 out of 62. im sure you can make them hit harder because im running 300 to a 450 rms speaker but they hit hard enough for me. also no bass boost was on because bass boost= bad. also you cant base a decision just on excursion videos. id also take SQ into account to and box sieze, type, power to each sub.if i got 2 of these off ebay and only ones that are left are the SVC. how would i wire them and what kind of amp should i get?thanks. and now maybe i might just get 2 Compvrs. oh my goodness i loved that video of the 10s can they pound harder then that? anyone else got a video of there PGs? and Compvrs? a hard decision i have to make here help me out.
