I had this subwoofer in a custom ported enclosure, hooked up to a Hifonics Brutus BRZ2400.1D. I ran it wired in parallel for 2 ohms (EXACTLY like every other dual 4 ohm sub I've ever had) at about 1500w RMS. All levels were turned down to less than 1/2. The sub lasted for four minutes at 15 out of 60 volume on my head unit with NO bass boost. After the initial song (Blunt Blowin' by Lil Wayne, not exactly a banger), I turned up the volume to 25. Within a minute, the sub blew. Cut it apart to see the damage and sure enough, both coils blown. I'm not impressed. As a matter of fact, I'm disgusted. Four minutes WAY below RMS? I understand its cheap, but damn.
Pros: Cheap and loud, while it lasted.
Cons: Cheaply made, poor sound quality even at low levels, power is FAR over-stated. I was only going to run it a few days while I waited for my new subwoofer to come in, I was anticipating blowing it. But not after four minutes, and definitely not at the wattage/volume I was running it at.
