I have a soundstream picasso 2 channel AB amp. Its 540 watts total rms but at 4 ohms its 180 watts rms x 2 channel. and at 2 ohms its 270 watts rms x 2 ch. i will be using 4 ohms. The model number for this amp is pcx2.540. The amp is huge in size it is 20 inches. I just want to make sure that i can just use one battery. Also i think i am going to use 2 12" SOUNDSTREAM arachnid subs that have 250 rms and 500 watt peak. I dont know to much about radio stuff but i just want a little system nothing huge. i would appreciate if someone could tell me if my radio system would be ok with one battery or do i have to have 2. thank you!
