dude ya one is enough as i took the 2 im selling and and a homie in club took out his big jl 15 and set my box in his car he has a 1000 watt amp and one hit harder and cleaner than his 15 easily,then hooked up both and sounded just as good, but needs more power as the cones barely hit and still rattled his lowrider, hes interested after hearing them, just waiting for his income tax, hopefully mine are sold, my 67 cj 5 just wont fit these lol, ya the k-5 blazer i was restoring has both glasses cracked where they latch on shell,had to unlatch them or would shatter the rest lol. yep when that big lifted k-5 rolled up with 4-6x9s,2-6.5s,2 13w7s with a hifonics bk1605 super d on each and the audiobahn for the highs hittin, ya felt it from the neighborhood, it flat out would hurt ya chest,i was the onlyone at the stolights ya could hear lol.anyways these w7s are bad *** subs, wish i could find something to put them in,but selling mainly to make a point to my nephew who the k-5 and all this was for to graduate, but he messed up, so im letting it go to show him a lesson.
