Query: what bump where?

Uh, I bought this about 2 days ago. Very happy about the shipping, got here super fast. However, I'm pretty sure my 250 watt mono amp hits so much harder then this. I'm actually 90% sure i'll end up returning this shit. Easy set up, but I might just get my money back, and put a little more for a bit better.
