The lightning from walmart is not the 3hp lightning sub, not even close. It was a 300/400 rms in 10/12 very nice cheap sub. My friend had 2 12's sealed, not the greatest SQ by far, but would outwang 2 PR-12's sealed anyday off the same amp.
I have used those older VR3 amps for midbass channels only, I did like them for a low power kit. Very clean sound, with no whine or thump. I have seen those ribbon tweets, my walmart audio worshipping nephew just bought a pair and is gonna hook em up. I aint seen em, but he claims he gonna run em on his 250.4 Directed with his other components..........
