If your boot is packed already (shopping, child buggy, items for the local charity shop), but you’re craving serious sound, these new amplifiers from JL Audio, now a Garmin company, are worthy of a look. Just launched are two models in the RD line: the six-channel RD800/6 (800W total) and the five-channel RD900/5+ (900W total), which has a 3-way crossover advantage over its predecessor.
Each amp offers four channels of 100W into a 2 ohm load, then the six-channel has a pair of channels capable of 200W each into a 2 ohm load, while the five-channel has a 500W channel for a subwoofer. All channel pairs are bridgeable, with the RD900/5+ offering a 12 dB per octave high-pass filter, additional bandpass filter on its rear channels, and dedicated low-pass filter for the sub channel. The RD800/6, meanwhile, has triple high-pass filters or full three-way crossover capability.
They’re compact, efficient, and designed to pack a punch without cooking your wiring or sacrificing your boot space. Key features include NexD switching technology and low distortion under load, so if you’re building a serious install in a car that doesn’t have room for a full rack, these amps make a lot of sense. Pro audio performance meets everyday usability. Expect to pay around £500 for the RD800.6 and £570 for the RD900/5+ upon release.
