Ok so I'm looking to get a sub-woofer in my Nissan Frontier. It's a four seater but really only comfortably fits two people (It has two pull down seats in the back). I was offered dual ten inch subs, already in a box, with an amp for fifty dollars. The brand is lightning audio (Not an amazing brand but the speakers bump). If I were to take up this offer, it would make my car a two seater and would most definitely not fit anyone in the back. Should I take this offer, or should I just invest in one good woofer and make my car a three seater?
