Designed for drivers who need clean power in tight spaces, it supports RCA inputs, fixed low-pass filtering, and industry-standard wiring gauges for straightforward installation. Built with thermal management and a simple control layout, it balances performance and usability for door speakers, coaxials, or a focused sub\/bridge configuration.\n\n\u003ch3\u003eHow does the TS 400x4 improve my car's sound quality?\u003c\/h3\u003e\n\nThe amplifier provides stable power delivery to reduce distortion and let speakers reach their proper dynamic range. Its Class D design keeps noise and heat low, resulting in clearer mid and high frequencies compared with undersized head-unit outputs.\n\n\u003cul\u003e\n  \u003cli\u003e400 watts RMS total across four channels for cleaner headroom\u003c\/li\u003e\n  \u003cli\u003eFixed 90Hz low-pass filter (-12dB\/8º) to protect speakers and shape bass\u003c\/li\u003e\n  \u003cli\u003eLow-noise RCA input stage for cleaner signal transfer\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCan I bridge channels or run a mixed speaker\/sub setup?\u003c\/h3\u003e\n\nYes — two of the amplifier's channels can be bridged to provide higher power to a single speaker or small sub, while the remaining channels feed separate speakers. The amplifier's channel configuration supports flexible layouts for front\/rear systems or a powered subwoofer alongside full-range drivers.\n\n\u003cul\u003e\n  \u003cli\u003e2 bridged channels option for increased output to a single load\u003c\/li\u003e\n  \u003cli\u003eMultichannel routing for front and rear speaker pairs\u003c\/li\u003e\n  \u003cli\u003eRCA inputs simplify integration with most head units or processors\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat are the installation and wiring requirements?\u003c\/h3\u003e\n\nTaramps includes clear wiring specifications so installers can choose the correct cable sizes for safe and reliable operation. The amp uses common automotive wire gauges and requires a 20A circuit breaker or fuse to protect the power feed.\n\n\u003cul\u003e\n  \u003cli\u003ePositive\/negative power cable: 11 AWG for stable current delivery\u003c\/li\u003e\n  \u003cli\u003eOutput wires: 15 AWG for speaker runs up to moderate lengths\u003c\/li\u003e\n  \u003cli\u003eRemote turn-on wire: 18 AWG and recommended 20A fuse\/circuit breaker\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow does the amp manage heat and long-term reliability?\u003c\/h3\u003e\n\nThe TS 400x4 uses Class D efficiency to limit heat generation and a heat-dissipating chassis design to move the remaining thermal load away from sensitive components. This combination supports consistent performance during extended use and in warmer vehicle environments.\n\n\u003cul\u003e\n  \u003cli\u003eCompact, ventilated housing for effective heat dispersion\u003c\/li\u003e\n  \u003cli\u003eLow-heat Class D topology reduces thermal stress on parts\u003c\/li\u003e\n  \u003cli\u003eDurable connectors and mounting points for secure installations\u003c\/li\u003e\n\u003c\/ul\u003e\n\nWho is this for\n\nThe Taramps TS 400x4 is aimed at car audio enthusiasts and installers who need a small yet capable multichannel amplifier for door speakers, coaxials, or a hybrid system with a bridged sub channel. It works well for compact builds where space is limited but reliable power and sensible control features are required — ideal for daily drivers, small show cars, and audio upgrades from weak factory amps.\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: What speaker wire gauge should I use with the TS 400x4?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Use 15 AWG for speaker outputs as recommended; use 11 AWG for power leads and 18 AWG for the remote.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Does the TS 400x4 include a crossover?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes, it includes a fixed low-pass crossover at 90Hz (-12dB\/8º) to shape bass response.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"Taramp's","offers":[{"title":"Default Title","offer_id":54581967389011,"sku":"B07YVMJFB9","price":80.51,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1095\/4257\/2371\/files\/taramps-ts400x4-front-panel.jpg?v=1786642087","url":"https:\/\/findsworth.co.uk\/products\/taramps-ts-400x4-4-channel-car-amplifier-400w-rms-compact-class-d-bridgeable-channels","provider":"Findsworth","version":"1.0","type":"link"}
