That's what I did at first, but something just didn't sound right. At higher volumes it sounded underpowered, like it was dipping out certain parts of the songs. Hard to describe as I'm not an audiophile, but if bass was hitting, guitar and vocals were all together at the same time in a song much of the base would be reduced coming from the subs. Sounded like someone was wiggling the volume knob almost. And the factory volume just wasn't that loud at full tilt, which led me to want to amplify the speakers, which led me down the rabbit hole of what I ended up with in the previous post.
