That really depends. Those PB4ks are very solid reputable amps. i was going to buy one a while back from a local shop willing to help with a competitive price. if i remember right it was $850 all in. These VFL 200.1's are one of the best amps i have had the pleasure of owning and playing with. we clamped 2300rms at .5 dropping tto 11.6v!! and rising to 2.3ohm! thats amazing for a 2k rated amplifier. it doesnt get hot even in those conditions. however the American bass vfl 200.1 is nearly as expensive as the pb 4k if u can get competitor pricing on the PB.

my plan is to run 4 vfl 200.1's on the 4 XFLs. That will be a long term project as funds are not the most plenteful for me.

the pb amps here $1000 plus tax and thats supposibly is competitor pricing. think your getting a way better deal. My amp has 2 xw power batteries running it and it clips when drops in power and gets hotter then a fire cracker, even to where it goes into thermal protection. I think some of that mind you is cause by the tuning i have on amp that i plan on changing. either way I was just thinking i'd be better off running 2 2k's then one 4k, and them ab amps look strong.

what impedence are you using your pb at? are you sure your not clipping the crap out of the amp from bad signal?

my pb runs a 1 ohm load. I have 6 runs of zero gauge from the battery under hood to battery in trunk. 3 positive runs and 3 negative runs, also have the big 3 done. In the trunk for battery power I have a xs power d3100 and a xs power d2700. I have the amp set to about half gain and low pass is set to about 30 and I use no bass boost.

thats weird those amps are usually very very sturdy. maybe you have a dud.
