So i had the sound shop build me a system for under the seat of my extended cab silverado. He ended up doing a Atrend box (down fireing) with 10 inch kicker 10C's (2 subs). This setup just dident have volume i wanted and couldent get low to save its life. I called him back 2 months later saying i want more bass so now we are going with a kicker CVRs. Thing is i wanted to go with some JL W1's or Alpine Type R's but he says kicker is the only way to go with a small enclosure. i find that so hard to beleive? whats your thought. and he said something about that JL arent made in the USA anymore so they arent as good as they used to be.
