...rs that demand the heavier power load requirements to be able to perform the way they were made to.
Strapping Capable - You are able to strap two AC4000.1D amplifiers and double the power that is being sent to your subwoofer(s). You now have the ability to connect more subwoofers to take advantage of the extra power.
Variable Bass Boost - Bass Boost allows you to adjust the low bass within the boost range to just the way you like it.
Variable Subsonic Filter - To prevent your subwoofer(s) from bottoming out, the variable subsonic filter filters out frequencies below the subwoofer(s) specified low frequency limits and allows the driver to reach a maximum safe excursion.
Variable Low-Pass Crossover - Subwoofers reproduce sound based on a number of different low-range frequencies. You can set exact sound specifications for the bass frequency reproduction.
