Livewire Elite 12g Speaker Cable Banana to Speakon 50 ft. Black

For a year, I've been using an old 50ft 14awg speaker cable from my Crown XTi 4000 bridged into a Dual 18inch Sub. I supposedly getting 3200watts but the sub sounded like 300w before the amp would start clipping. So I added a subsonic filter at 30hz and a Peak Limiter and it still performed the same! So I thought my amp was defective or was suffering from low voltage. Until one day, I went to a outdoor DJ festival were the subs sounded powerful, deep, and aggressive. I curiously went behind the subs I found that they were using LiveWire Elite cables! Then I did some further research about speaker cable size and length, then I decided to buy this cable. The moment I plugged it in, I WAS AMAZED! Not only did my sub sounded louder, but now I can really feel the gut-shaking BASS! Now my sub sounds just like what I heard at the festival. PROBLEM SOLVED!
