Currently I have a Hifionics bxi2610D amp that says it puts out 2600 watts rms. My sub is a pioneer premier TS-W8102SPL which i have wired down to 1 ohm. The Hifionics amp just isn't pushing the sub as well as I had hoped so I was looking into the Crescendo BC3500D amp. It fits my budget and I was wanting to know if it would be a lot better than the Hifionics amp or if there is another brand that would be better for the same price. I have upgraded electrical system with a 250 amp alternator and have two Kinetik HC1800 batteries so I know the power to the amp is good just that the amp isn't putting out the power that is needed. Thanks for your help.
