Thx for the link bro, it really help!!
Nola, not SPL purpose lah, but sometimes i'll boom boom 1. Im currently using 1 kenwood 10", feel like the woofer cannot tahan when i open too loud. So, plan to get a 12" lo. Then my fren offer me this Oxygen woofer. Btw, my fren used these woofer to boom in the autoshow b4, izzit will affect the quality of the woofer??? He told me new 12" woofer selling for 350++ la, now he is trying to let go at half price lo. Acceptable??? I just noob to ICE, just hope ICEr out there can help me.
