{"product_id":"4-channel-car-amplifier","title":"4-Channel Car Amplifier","description":"The Pioneer GM-A4704 is a 4-channel Class AB car amplifier engineered to elevate your in-car audio experience. It provides a significant power upgrade over factory systems, delivering 40 watts RMS to each of your front and rear speakers. This allows for clearer playback of finer musical details, especially at higher volumes needed to overcome road noise.\n\nThis versatile amplifier offers multiple configuration options. You can use channels A to power your front speakers and bridge channels B to drive a subwoofer. Alternatively, it can be set to 2-channel mode, outputting 130 watts RMS to a pair of component speakers or subwoofers. The GM-A4704 includes speaker-level inputs, making it compatible with factory head units that lack pre-amplified outputs. It also features selectable high-pass and low-pass filters and an adjustable bass boost for further sound tuning.","brand":"Pioneer","offers":[{"title":"Default Title","offer_id":52663261266232,"sku":"GM-A4704","price":130.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687524670.jpg?v=1784325444","url":"https:\/\/store.motormia.co\/products\/4-channel-car-amplifier","provider":"MOTORMIA","version":"1.0","type":"link"}
