Ok so i have a Mono RF 501 BD amplifier that has 1 slot for positive and 1 slot for negative. It is allen wrench. I have a new box that is ported single chambered 2 terminals. I tried hooking it up by putting both positive speaker wire in the positive slot in the amp and same for negative but it seems like my output is not nearly what it should be. When i play only one sub, the bass is louder. Am i bridging them right. I have 2 SVC 4 ohm subs that are wired to a 2 ohm load if that matters. Any advice is greatly appreciated..
