ok i cant post in the audio section so dont flame me. anyways my sub doesnt hit right. i dont know how to properly adjust the LPF and HPF. the sub only vibrates a little. u can barely notice, but when i turn the LPF up it hits harder but then the amp goes into protector mode. the amp is a Sony Xplode. i dont know what the deal is. i ran 8 gauge power wire to the amp and still the same problem. so help me out guys.
