Sound Storm Laboratories CG12D 12 Inch Car Subwoofer - 1200 Watts Maximum Power, Dual 4 Ohm Voice Coil, Sold Individually

Sub slaps. Have nothing bad to say about it. Maybe I'm one of the lucky ones. I'm running on a power acoustic 2500w amp in a small ported box tuned to 28hz and it sounds great.

for the price,Exceptional quality ,durable construction, just make sure to adequately "break it in. " on low to medium.. just put it in a box, and jam some bass testers on low volume with no gain for 3 hours... it helps allow the rubber poly to be more flexible.. , also.. since it is dual 4 ohm. Vc , connect the positive to the positive and negative to negative on the speaker with a short wire.. and it will run at 2 ohm. 600w Rms.. only do this if your amp is 2 ohm stable.. and you have an adequate size power wire .

for now they are working fine we will see what happens when i put the watts to them

After wondering why 2 of these didnt do well and locked up. I cut the apart and found out it has been fighting the epoxy/resin they used was alll over the coils and motor making it sticky. I didnt know that was the problem until they blew. No i didnt return them because i wanted to know if it was me or the manufacturer. I blame ssl for the epoxy on the coil and motor and all in the dust cap. Poor quality control. Just an fyi for all that say the marks came from it blowing. You are incorrect. I have cut open many woofers these qc issues happen. From original when i installed them. They was stiff at first "epoxy in the motor".

Wasn't flush after mounting
