Quoted from lllvjr:There's no output to a sub...
From the IGN article…
"Speaking of rocking out, 10 KISS songs blast over Stern’s reworked sound system while you play: Deuce, Hotter Than Hell, Lick It Up, Shout It Our Loud, Detroit Rock City, Calling Dr. Love, Rock & Roll All Night, Love Gun, Love It Loud and Black Diamond. Paul Stanley and Gene Simmons hit the studio to provide custom call-outs, as well. Sound is a big deal with a rock-themed game like KISS, so be nice to your local arcade operator and maybe she’ll let you plug into the audio out jack that’s standard on Stern’s new CPU board."
Not sure if you can hook a sub up to this audio out jack they mention.
Quoted from Flack:I didn't catch it in the promo, but did anyone hear when it will be out? It looks far from being ready.
I think when they released the Metallica teaser it was just like this as far as showing pf toys and bits of not done art. Metallica was 2 months away if I remember correctly.
