For sale is a brand new, still wrapped, in box, manuals and all JL Audio 300/4 amplifier. The 300/4 in my car was acting up so I went and had it sent off to JL for repair. However I didn't want to be without music while waiting for the amp to come back so I bought another 300/4 and put it in my car. Apparently they couldnt fix the old one because they just sent me a brand new one. Retail on this item is 499.99 at most JL dealers, and thats how much I had to pay for it. I am looking for around 350 or so, shipping included. PM me for any additional questions. I will post pictures when I get a chance later today. Thanks!
