LOL, can't do 20hz. Overall, nice to listen to, cuz the headunit has a seperate sub level control, I have it turned mad low. PPl don' expect mad bass and loud wide range voice comin out of a fresh clean CX-7, I like drivin by X5's & FX's, among other new cars. Cuz theres Bass, then theres Bass accompanied by properly equalized vocals and highs.
CX-7 Heaven - I ripped the wires within the L7. U know if it can be repaired? ur into subs u'll know what i'm talkin about. My L7 is 5 yrs old, so Warranty is over, they repaired that same problem once for free, actually they just gave me a new one, but it happened again, its so simple, the wire that goes from the spring loaded connecter to the gluey area under the woofer. I'm gonna use a twin S8L7 setup when/if I get it repaired.
