Assalamualaikum All
How are you? I am trying to find a nice subwoofer not the chinese one. I am currently having JBL s2-1224 (vented) and crossfire cfa600 2 channel 600w rms. For speakers i have rockmars 4800 4 channel amp connected front jbl cs 762 series and in the back i have 7930 ( which i dont like). Headunit is pioneer avh 165. I am searching for a good subwoofer that can really give me deep bass beats. Need expert suggestions too.
