Source: jlaudio.com (verified 2026-07-11) · corroborated by driveinautosound.com. The official JL Audio product page (source) now redirects to Garmin's catalog (JL Audio is a Garmin brand) and renders no spec table, so specs were taken from DriveInAutoSound, which reproduces JL Audio's official published spec sheet verbatim. Its SKU "RD900/5" and UPC 699440986427 confirm this is the exact 5-channel RD-series model, not the HD900/5 sibling or the RD900/5+ variant. That page states, verbatim, Rated Continuous (RMS) Power @14.4V: main channels 70 W x4 @4Ω, 100 W x4 @2Ω, bridged 200 W x2 @4Ω, subwoofer 225 W x1 @4Ω / 500 W x1 @2Ω, total 900 W, main-channel frequency response 12 Hz–22 kHz, S/N >104 dB (referred to rated power), 80 A fuse, minimum impedance 2 ohms, and Class D topology. Both DriveInAutoSound and ClassicCarStereos price it at $679.99 (DriveInAutoSound reg. $799.99); THD+N is left blank on both pages, so thdPercent is null. (Note: ClassicCarStereos lists 75 W x4 @4Ω, which conflicts with JL Audio's official 70 W x4 rating reproduced on DriveInAutoSound, so 70 was used.)
