My audio system consist of these items:

Subwoofer--> just one 12'' Memphis PR12S4------250RMS & 500max
Amplifier---> Kicker 120.2 im guessing it will support 120watts to 2 subs

Question is: How many watts is my sub getting 120watts or 240 watts cuz im just running one subwoofer, and on the part where u put your speaker wire from your sub to your amp( that connecting area part) it has one connecting thing on the far left for sub #1 and to the far right it has a connecting thing for sub #2, question is, i wired the (+) on the far left and wired (-) to the far right, is this correct

If someone asked me, how many watts do you have on your system what am i suppose to say? Do i add the RMS watts from the amp and the RMS on the subwoofer together or do u just add the amp RMS watts???
