This car graphic equalizer features high-level speaker inputs, which means it can accept the speaker-level signal directly from a factory (OEM) head unit — no RCA pre-outs required. This makes it an excellent upgrade for vehicles with stock stereos.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can I use this equalizer on a boat or motorcycle?\u003c\/h4\u003e\n\u003cp\u003eA: Absolutely. The unit is designed to work on any 11–15V DC negative-ground electrical system, making it compatible with cars, trucks, RVs, boats, and motorcycles. Ensure it is mounted in a location protected from direct water exposure for non-automotive applications.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What is the subwoofer frequency range on this equalizer?\u003c\/h4\u003e\n\u003cp\u003eA: The subwoofer output covers a frequency range of 35Hz to 250Hz, giving you broad control over the low-end performance of your car audio system. The dedicated subwoofer volume control lets you dial in the exact amount of bass you want independently from the rest of the mix.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How difficult is it to install this car graphic equalizer?\u003c\/h4\u003e\n\u003cp\u003eA: Installation is straightforward. The package includes mounting brackets and screws, and a full instruction manual walks you through the process. Most users with basic car audio wiring experience can complete the installation without professional help. Always disconnect the vehicle battery before beginning.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"Is this 7-band car equalizer compatible with factory head units?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Yes!
