Bad Subwoofer?!

[bass_addict07]

i have an apline type r 15" and a mrp m1000 running at 2 ohms and wen i first installed the system i had a shittty dual head unit and i wuld crank it up now and then and the amp wuld clip because it wasnt recieving a good enough signal and this happened around 10 or more times. well now i have an alpine head unit and it never clips but wen ever i turn the gain up a little bit and the bass boost up a little bit you can hear like a popping/knocking noise and it sounds like something is loose inside the woofer. so is my subwoofer bad or wat? cuz i kno it can handle the amount the amp is giving it, the gain isnt even halfway.

thanks

turn the bass boost all the way down....and read up on how to CORRECTLY set the input level adjustment.

Its called clipping the crap out of the amp and making the sub sound like ass. I've never heard any mechanical noise from my Type R even while playing 10Hz tones full blast in my t-line.

after adjusting your gain, dont mess with ANY bass/loud/boost settings period.
