Finally got a chance to actually drive the Jeep with the new stereo. Holy cow what an improvement!
It was a short jaunt, as I had to transfer the kids back to their mom this morning.
On the way over there, I heard background vocals on The Raconteurs' Steady As She Goes that I'd never heard before. I was worried that as it was streaming (SiriusXM app) that the limited quality of the source would limit the value of the stereo components, but it was great.
After dropping them off, I threw in a CD of Dr Dre's 2001 album, and turned it up a little more. Though the sub is only 8", it's plenty when you push a couple hundred watts through it. More bass than that would be unbalanced for my taste.
It's still not fully tuned, as I haven't had time, so I just set the gains to midpoint and crossover to the specified frequency range of the sub. Probably need to play around with the radio's EQ as well as I think the treble is a little too high. But man, I forgot what it was like to have a GOOD system.
