Two keys to unlocking great sound in a car stereo system are extensive control and serious power — and this amp’s got them both. For control, AudioControl’s D-5.1300 provides an expansive digital tuning workstation with a connection to your laptop. For power, this five-channel amplifier puts out 100 watts RMS to four channels and up to 500 watts RMS to a sub. If you’re into mega-power, competition-type systems, you could bridge this amp to 3-channel mode and drive a couple of high-performance components with 400 watts RMS each while powering a sub with 500 watts RMS — that’s 1300 watts in total.

Computer-controlled digital signal processing

You won’t find any knobs on the D-5.1300 — you make adjustments and save settings via your laptop (PC or Mac). AudioControl’s Smart-User DSP software package includes 12 or 24 dB/octave Linkwitz-Riley crossovers, 30-band equalizers, parametric filters, time delay/alignment for inputs and outputs, phase correction, AccuBass™ bass correction, and real-time analyzers (RTA) for the inputs and outputs so you can visually confirm the improvements in the sound.

It’s made to work with a factory radio

Eight active speaker-level inputs allow you to connect this amp to almost any factory system, even ones that have separate pre-filtered, time-aligned, and amplified signals going to separate factory speakers and tweeters. The D-5.1300 sums them into one smooth, unified signal for you to balance, align, and tune for your high-performance speakers. AudioControl’s Great Turn On (GTO™) signal-sensing circuitry turns the amp on automatically whenever it senses an incoming signal, so you won’t have to run a separate turn-on lead back to the receiver.

Active controls for active systems

This amp will work well, for example, with a 3-way system that uses tweeters, midrange speakers, and a subwoofer. Highly adjustable crossover networks let you set high-pass, low-pass, and bandpass filters so each driver gets only the frequencies it was designed to play. AudioControl’s AccuBASS® circuit ensures maximum bass performance, even if you’re connected to a factory radio that normally turns down the lower frequencies as you turn the volume up
