{"product_id":"j2-320-4-4-channel-amplifier","title":"J2 320.4 4-Channel Amplifier","description":"The JL Audio J2 320.4 is a 4-channel car amplifier designed to power your vehicle's sound system with 60 watts RMS per channel at 4 ohms, or 80 watts RMS per channel at 2 ohms. For more demanding applications, it can be bridged to provide 160 watts RMS to a subwoofer or two speakers at 4 ohms.\n\nThis Class B amplifier utilizes a MOSFET switching power supply for efficient operation. It features differential-balanced inputs to minimize noise and interference. For precise audio tuning, the J2 320.4 is equipped with variable low-pass filters (40-150 Hz) and variable high-pass filters (60-1.2 kHz), both with 12 dB\/octave slopes. A variable bass boost feature allows for 0-12 dB enhancement at 45 Hz.\n\nConnectivity options include both preamp and speaker-level inputs, making it versatile for integration with various head units. The amplifier has a frequency response of 10-25 kHz and a THD of 1% at its rated RMS power. The recommended fuse rating is 30A x 2, and 4-gauge power and ground leads are advised, though wiring and hardware are sold separately. Its dimensions are 15-13\/16\"W x 2-3\/16\"H x 9-5\/8\"D.","brand":"JL Audio","offers":[{"title":"Default Title","offer_id":52662777250104,"sku":"J2320.4","price":199.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687497055.jpg?v=1784320851","url":"https:\/\/store.motormia.co\/products\/j2-320-4-4-channel-amplifier","provider":"MOTORMIA","version":"1.0","type":"link"}
