Now what is wrong?

Ok so I was told to upgrade my amp since it only put out 360 watts rms and my subs are each 300 watts rms. I got a good deal on an UltraLinear ulz1001. I read good reviews on it so I said why not. It is rated at 1000watts rms @ 2 ohms. I have my subs hooked in parallel to the 1 channel since it's a mono amp. I've been very disappointed, the subs move a lot more than they used to it seems, but the bump is not there. I am running 4 gauge power and ground and 12 gauge speaker wire. I was wondering what could be the problem. How can I check to make sure my ground is good and the amp is getting enough power? Is my power and ground big enough? I've fooled with all of the adjustments on the amp but can't really figure anything out with that. What should they be set to. There is a gain, lpf, sub sonic and bass boast knob. There is also a switch for full or LPF. These two 10" subs are in sealed boxes. Do I need to upgrade my alternator? Do I need to do this Big Three Upgrade? Cap? I'm really clueless as to what I need to do. Thank you guys.

Make sure your low pass filter isn't all the way down, I know I made that mistake when I tuning my amps for the first time. Also, do not get a cap they are a waste of time and money.

Make sure your subs are not wired out of phase.

Problem: You want the "bump".

Reason you have a problem: 300w RMS.

I figured it out. One sub was wired opposite inside the box. Now they boom just fine.
