**Alpine Type-R Making Popping sound - subwoofer not blown - amp not clipping** ( Just fixing the title lol )
First post here //content.invisioncic.com/y282845/emoticons/veryhappy.gif.fec4fed33b4a1279cf10bdd45a039dae.gif BTW great forum, ive learned so much from here, kudos to the contributors.
I am facing a little issue with my subs, bought them used. I got two Alpine Type Rs 1243D 600 Watt RMS and hooked them up to Hifonics Brutus BRX 1516.1D.
Wired them down to 1 Ohm since both are 4 Ohm DVC.
The sub-woofers work fine at low volume, but they make popping and cracking sound if I give them even around 300 RMS each. Spider is intact, but i fell like its very stiff. I can push down on them but no crunching or scraping noise when i push down on the cone, its smooth. Checked with a volt meter the impedance of the coils, they are all giving around 4 Ohm so I know the coils are fine. Gain is at 50%. my JL w3s that are 500RMS bang hard with gain 75% no distortion same setup.
Im really not sure what the problem is, im so confused. Thanks for the help in advance //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
