A friend of mine just put in a 5-channel amp and 4 new speakers into his Honda Accord. It sounds quite nice, but he still lacks the sub. I have an 8″ JL Audio in my Maxima so we compared it with some 10″ subs and they didn’t even compare. My little sub hit lower and clearer, so now he’s looking for a JL Audio. It’s nice to know I got such a good sub. Now I’m wondering if I should upgrade my system from the stock speakers and put in an amp. Hmmm.
