Hello i have 2 sundown SA-D12's in a sealed box with 1cu ft each speaker firing down at the floor under my back seat of 2008 Silverado crew cab. I need an amp recommendation for the 2 subs they are 750 rms each and i would like a remote bass knob. What should i get ? I need something that doesn't fade out after playing hard for an hour or more. Thankyou
