Hi, VP's going to be the man to listen to in regards to what will work best but from what I've read the Vibe gets good reviews and is very well priced. Almost went for one myself instead of the JBL. Ideally I wanted to go stealth with the JL XD600/6 but had to reign the budget in a little bit as it's a good £500+ over here. My next upgrade will be a trunk sub of some description, replacement amp and either all stealth or visible but sexy !
