Hey everyone. First time forum user.. I have 3 years of audio experience, so I'm still noob (ish). I'm rocking an x18 in 6.15cft @35hz on a rf p1000bd, for now. I have a ts2.8kw currently in transit! Then the rebuild starts! I am partial to rockford and sundown and this will be my first venture from my comfort zone. Any advice will be received with a listening ear and appreciative attitude. Thanks in advance.
