i have a Pyramid PB1836GX 2400 Watts 2 Channel Mosfet Amp, and one Pyle PL1295BL 1200 Watt 12'' High Power Die-Cast Subwoofer. i have not yet enclosed the sub because i have no 12" cabinets.
The sub has a low sounded buzz and no tone or thump to it. Am i under powering it, or is the noise due to the lack of air pressure from the absence of an enclosure?
You haveno thump because you need to put it into an enclosure. Unless it is a sub that you can use in free-air (most subs aren't) then this is why you have no thump.
check all your connections. Most likely it is the RCA wire. This should be on the OPPOSITE side of the Power wire. Putting the RCA next to the Power wire is a HUGE no-no and will cause the buzzing sound. if they do have to cross, make sure the cross at a 90 degree angle (perpendicular) This will reduce the amount of contact area between the two wires. Also, make sure you have the Low Pass (LP) switch ON. If you are allowing High frequencies into your subs, you will also get a buzzing sound and you WILL damage your subs.
