We consider it our mission to use our expertise in developing the latest technologies and to bring you the absolute best sounding amplifiers on the market at a reasonable price. From its clean, sleek design to its high quality components, you will be amazed at the quality and power that these new Phenom amps offer.\n\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-family: Arial; color: #000080;\"\u003eBefore we talk about the actual amplifier, I wanted to point out that we included a microphone. Most brands do not do this. We wanted to provide you guys with the best sounding marine amplifier of course. But we also wanted to give you the ability to have a microphone so you can use all the power of the system to communicate when out on the water. This will give you many new applications of what you can use your marine system for. We included a special circuitry in the amplifier that when you talk through the microphone the music will get lower and when you are done talking the music will go back to normal volume.\n\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-family: Arial; color: #000080;\"\u003eThe RXM-F4 is a 4 channel amplifier with 2,400 Watts peak output, 400 Watts Dyno Certified RMS power (4 x 100 @ 4 Ohms). You can also bridge the amplifier and get  2 x 1200 Watts RMS @ 4 Ohms. Here at Rockville we offer the best value in car audio. We therefore want to make it easy for you to compare our products to any brands on the market. The peak rating can be used to compare with brands who use peak ratings such as Boss and Power Acoustik while the Dyno Certified RMS rating can be used to compare with top brands such as Kicker, Rockford, Alpine, etc.\n\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-family: Arial; color: #000080;\"\u003eThe RXM-F4 has a conformal coating on its PCB (printed circuit board) in order to protect against moisture, dust, chemicals, and temperature extremes. This coating protects the amplifier from the elements of the ocean. If water gets sprayed on the amplifier you will not have to worry. The exterior screws are made of stainless steel to better withstand the elements. This amplifier is fully marine-rated from start to finish.\n\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-family: Arial; color: #000080;\"\u003eOne of the tricks to determine the real power of a car amplifier is to multiply the fuse rating by 10 to determine the true RMS power. This formula almost always works within 20%. RXM-F4 features a 2 40 Amp Maxi Fuses. Compare this to other amps on the market with similar fuse ratings and you’ll see that with the RXM-F4 you are getting your money’s worth and then some.\n\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"font-family: Arial; color: #000080;\"\u003eThis unit also features a high speed MOSFET power supply, studio-grade bipolar output stage transistors and ELNA brand audiophile capacitors. It has a fully adjustable 12dB\/Octave cross over with differential circuitry. With RCA inputs and High Level speaker inputsyou can run the signal to your marine stereo system weather you have an available preamp output available on your receiver or not. This amplifier is completely universal. It can be installed to any marine system.\n\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"font-family: Arial; color: #000080;\"\u003eOther features include Auto-Start Smart turn-on (This function senses when there is a signal from the head unit and automatically turns on the amplifier hence no need to run a Remote Turn-On wire), a fully adjustable 12dB bass equalizer, 2 ch\/ 4 ch input mode switch, mute and delay soft start technology, and a crossover band-pass control. The RXM-F4 is protected by a full IC controlled circuit and has professional peak limiter circuitry guaranteeing distortion free musical playback at all levels.\n\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-family: Arial; color: #000080;\"\u003eOne last point I want to make about this amplifier is efficiency. The circuitry of this amplifier is a class A\/B circuitry. Class A\/B is known to have amazing sound quality. Pro audio amps usually all are class A\/B. Class A\/B however is not known for its efficiency. To make this amplifier more efficient we simulated a class “G” amplifier. Class G is technology that switches the rail voltage depending on how much power is being used. We have similar technology built into these class A\/B amplifiers which make these about 65-70% efficiency which is just amazing for a class A\/B amplifier.\n\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-family: Arial; color: #000080;\"\u003eWe are so confident that you will be extremely satisfied with this amplifier that we are giving every customer a 30 Day money back guarantee. So purchase the amplifier and try it for 30 Days. If you are not happy, we will call tag it and cover return shipping costs and refund you all your money back.

All Rockville products go through the most rigorous quality control standards in the industry. Products go through months of extensive testing before they reach your hands. All user functions are tested and all internal components are tested for quality. Rockville makes products that are virtually un-breakable! Rockville is one of the only brands in its class to test every concept model for weeks or months before starting production. Once production begins, Rockville sends product engineers to their factory to quality control every line of production. During production every product is tested and on top of that Rockville goes the extra mile and has their high level product engineers do an additional quality control. They test a certain percentage of all products from the production line a second time to ensure that the quality meets their vigorous standards, and to make sure that there is never a batch of products with even a slight problem. All Rockville DJ\/PA speakers are backed with a full 1 Year warranty, though it is unlikely that you will need to use it.\u003c\/span\u003e","brand":"Rockville","offers":[{"title":"Default Title","offer_id":46935453827373,"sku":"RXM-F4","price":169.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0672\/0805\/3037\/products\/98017d50-46a5-415e-85d6-c6fae5b79c8d_878f55cd-d539-43d6-9b84-9b8002ed24f4.jpg?v=1702589359","url":"https:\/\/audiosavings.com\/products\/lowersubstitute-e5231","provider":"Audio Savings","version":"1.0","type":"link"}
