Most people like JL Audio for many reasons. I feel they are a great company with awesome products that will last longer than your truck. There is a reason why they are so popular. Everyone has different opinions on the subject so it really comes down to how much of a chance you are willing to take. I don't like taking chances when spending a good amount of money. I love the resale value JLs have as well. I can absolutely tell you reselling a JL setup will be much easier and retain more value than reselling something not as popular or unheard of.
This... I have 2 JL W6V2 12's from 2007. I had to recone them in 2014 (like $30 and some elbow grease) since the rubber finally deteriorated. They still work like new and I used to abuse the **** out of them. I can easily sell these suckers if I wanted to and make some decent money for speakers that are over a decade old. JL's reputation is very hard to beat.
