if you haven't made up your mind yet, the Fi Q is an awesome sub. we had one in a crap box on a crap sony amp and it sounded amazing. by far the best sql sub I've heard, though I've only heard 1

 

"JL slash over Sundown amps anyday and twice on Sundays" x2! Not even close to the same league IMO. Arc amps are nice. Still like JL slash better though.

 

The Arcs are at par with the JLs they both are in the same league - Price wise the Arc are the better suit - plus they have built in fusing, can't say that for JL. There's an added expense - wiring and fused distro block to the JL

 

In no perticular order

JL Slash
Arc KS
DLS Reference (www.sonicelectronix.com is an authorized dealer)
Memphis (MC line)

First decide if you need a 2 or 1 ohm stable amp for the subs.

 

IMHO as good as the JL slash amps are the JL HD amps are better.

 

is the sq better on the FI subs than the JL W7's?

 

Alright so im deciding to stick with the JL audio for amps. HD or Slash series. On the subs I'll probably go with the FI Q, or FI BL. Depending on if the sq is better on the FI subs. and now last haha, what do you guys think about cdt audio components? Im stuck between the CDT ES 6.5 components, and the focal k2p's.

 

Personally I like the Slash and they have better xover capabilities but if space is a concern the HD have a strong following.

IMO Go with the Focal. If you find the tweeter too bright bring them down -3db or go off axis.

 

no but they are cheeper

 

Yah space is no big issue, I have the whole trunk of 05 chevy malibu to put crap in haha(:
