I've read how people think the factory subwoofer is just "meh". But it's kinda hard to know exactly what it compares too.

Ok, I want bass and I don't want to give up trunk space, so it's factory sub or the basslink.

I don't need 400W 2x12" woofer bass. I'm reasonably satisfied with 2 6x9's running off a 25W per channel HU in a sedan deck. Is the factory subwoofer about this level of bass?
