I heard 2 of the G5 10"s today on 800 watts. I must say. I am very impressed. They are a bit pricey at $380 per sub, but the sq/spl on these were amazing. These 2 10's dropped lower then many 15"s I've heard in similar vehicles. The 800 watts the guy said was nothing to them, they could take 1000-1200 easily. Even at that price, they are worth every penny.
