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
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
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 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
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: 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

Customers say
Customers find the amplifier to be of good quality and value for money, describing it as a nice affordable mid-size unit with great sound that bangs louder. The functionality and wattage receive mixed reviews – while some say it works well and has plenty of power, others report it stops working and doesn’t deliver the rated power. The heat level is also mixed, with some saying it never gets too hot while others report it overheats very quickly. Additionally, the longevity is concerning, with multiple customers reporting it dies after only two months of use.

Great amp
I used this to replace a Kenwood that finally died, I’ve got 2 memphis 12 street reference and this amp pounds them better then the Kenwood did! If you know how to properly adjust your amp you won’t have any issues!

Years later pleased purchase
Had for 2 years in a Challenger. 2 10âs and 1 12. During the 1st months I drove to places like Las Vegas to Reno and Las Vegas to Phoenix when I stayed in Vegas. Never overheated. Never just randomly shut off and if you know them are hours of constant use. Now back in Ohio I still have it, still going strong and no problems. Also have a Pioneer radio.

Overheats rms ratings fake
Terrible subwoofer, the rms ratings are completely false not even half the number it claims. Pushing one skar 12â it overheats in 40 mins and even when I turned the power down the outcome is the same. I did more research and learned that mostly all planet audio RMS ratings are not true at all. Will never go with planet audio and alternative is skar itâs new a some may never heard of them but itâs worth the extra bucks to be able to get the RMS you need and want for the bass heads.
