I've been looking at getting 4 of the JBL GTO8627 Grand Touring Series 6X8s. Here they are on Crutchfield. Has anybody run these? Are they a pretty nice sounding speaker? I'm not looking for anything spectacular. I'm just looking for a nice drop in speaker to replace the worn out, 15 year old stock speakers . They're gonna be powered by a JVC KD-SH707 HU. I'm considering them, but I'd like to hear what you guys have to say first.
