Quality, Efficiency, and Convenience with JL Audio XD Amplifiers

JL Audio's XD400/4 4-channel XD series amplifier encompasses high quality at an affordable price. When JL Audio sets out to make an affordable amplifier the one thing that you can bet they will not do is compromise on quality and performance. XD amplifiers feature NexD Class D Technology, that reduces distortion and increases efficiency. The use of an Advanced Rollback Protection system will allow the XD amplifiers to maintain both thermal and low-impedance protection by either limiting available peak voltage when overheating or rolling back peak voltage when low impedance is presented at the outputs. In order to minimize engine whine or alternator noise, XD amplifiers feature differential-balanced inputs that eliminate voltage sensitivity between one input terminal and ground thus reducing the occurrence of interference. In addition to all these great technologies, XD amplifiers also feature a relatively small chassis, making them easily mountable in any vehicle without extraneous hassle. When looking for a space-saving amplifier loaded with the latest technologies and unsurpassed quality and performance, then look no further than JL Audio's XD series car amplifiers.
