I have 3 15s that have never been played daily, only for burps for some shows and that's it. Very little testing, I usually just go to the show and burp. The reason I'm selling is because I'm trying to fund a new set up. I am selling each for $300 or $800 for all 3. If local, I can give you a free box that does 158s all day. This box is for a s10 but could be placed in almost any suv. Let me know if your interested. Function is 100% and looks are 100%. Nothing wrong with these subs. I have run 2 memphis mc1.4000, 2 rd d9s, and now 2 cactus 5ks, I always hit 158 with these amps. I did hit 159.1 once with the 2 cactus 5ks, with the box I'm throwing in. I will send pics if I must, but everyone on here knows me, and I'm straight up.
