Specification Brand : Planet Audio BulletPoint1 : Power - 4000 Max x 1 @1-Ohm, 2000 Max x 1 @2-Ohms, 1000 Max x 1 @4-Ohms, 8000 Max x 1 @2-Ohms strapped BulletPoint2 : MOSFET Power Supply - A MOSFET is an electrical switch that allows the flow of electrical current. It controls the output voltage and current precisely by removing the output current sensing loss & eliminating all secondary feedback circuitry BulletPoint3 : Class D - Power loss is significantly reduced making the amplifier highly efficient. 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 BulletPoint4 : 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 BulletPoint5 : Strapping Capable - You are able to strap two PL4000.1D amplifiers and double the power that is being sent to your subwoofers. You now have the ability to connect more subwoofers to take advantage of the extra power BulletPoint6 : 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 BulletPoint7 : 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 BulletPoint8 : Specs - Dimensions: 13.90” x 7” x 2.39”, Weight: 8.2 lbs., Speaker Impedance: 1 to 8 Ohm, THD @ RMS Output: 0.01%, S/N Ratio: 100 dB, Frequency Response: 15 Hz to 250 Hz, Fuse Quantity: 3 40 Amp ATO Blade BulletPoint9 : Planet Audio provides a powerful 6 year Platinum Online Dealer Warranty so long as the purchase is made through Amazon.Com.

What do you do to convert the vehicle's unique antenna plug to the standard DIN (Motorola) required by most aftermarket radios and modulators? Simple, you add an antenna adapter cable. That will convert the factory unique antenna plug (car side) to standard DIN plug required by most aftermarket products in need of an antenna signal. These antenna adapters are small jumper cables, usually less than 6 inches in length. And Vise versa for Female Plug. This combo pack includes two adapter cables. Antenna Adapter Kit Antenna adapters with snap lock For adding CD changer or other external device with built-in FM modulator Parts Included : 1 - Vehicle Antenna to Standard Male Motorola - 6" Long 1 - Factory Radio to Standard Female Motorola - 6" Long INSTALLATION: 1. Connect the Male Adopter to the factory unique antenna plug (car side) 2. Connect the Fe-Male Adopter to the Aftermarket Radio or FM Modulator antenna plug (Equipment side) ProductSiteLaunchDate : 2016-03-10T08:00:01.000Z Size : 4000 WATT SpecificationMet : certified frustration-free StreetDate : 2014-05-15T00:00:01Z Style : 4000 Watts Monoblock SupplierDeclaredDgHzRegulation : not_applicable SupplierDeclaredDgHzRegulation1 : not_applicable SupplierDeclaredDgHzRegulation2 : not_applicable SupplierDeclaredDgHzRegulation3 : not_applicable SupplierDeclaredDgHzRegulation4 : not_applicable SupplierDeclaredDgHzRegulation5 : not_applicable UnitCount : 1 UnspscCode : 52161547 Voltage : 16 volts WarrantyDescription : 1 Year Replacement Warranty Wattage : 4000 watts
