Excess energy is stored until it’s needed instead of being converted into heat. Reduction in size/weight, reduced power waste, smaller heat sink, compact circuitry - 1 Ohm Stable - Able to continuously power loads of 1 Ohm without encountering difficulties such as overheating. Typically made to power up subwoofers 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 AR4000D 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 - Specs - Dimensions: 14.3” x 6.5” x 2.8”, Weight: 7.96 lbs. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B004RS9UTI | | Best Sellers Rank | #39,647 in Electronics ( See Top 100 in Electronics ) #63 in Car Mono Amplifiers | | Brand | BOSS Audio Systems | | Brand Name | BOSS Audio Systems | | Customer Reviews | 4.1 out of 5 stars 586 Reviews | | Global Trade Identification Number | 00791489116404 | | Included Components | Remote subwoofer level control | | Item Dimensions | 14.3 x 6.5 x 2.8 inches | | Item Type Name | BOSS Audio Systems AR4000D Class D Car Amplifier - 4000 Watts, 1 Ohm Stable, Digital, Monoblock, Mosfet Power Supply, Great for Car Subwoofers | | Item Weight | 8 Pounds | | Item dimensions L x W x H | 14.3 x 6.5 x 2.8 inches | | Manufacturer | BOSS AUDIO | | Material Type | Metal | | Maximum Output Power | 4000 watts | | Model | AR4000D | | Mounting Type | Car Mount | | Number of Channels | 1 | | Output Power | 4000 Watts | | Part Number | AR4000D | | Specification Met | FCC | | UPC | 803983124578 807032956639 791489116404 | | Voltage | 10 Volts | | Warranty Description | 6 Year Platinum Online Dealer Warranty valid only on products Sold / Shipped by Amazon.com.
