About the AudioControl A1500.1
From our tech experts at CEN
The AudioControl Altitude A1500.1 is a monoblock subwoofer amplifier from the Altitude Series, rated at 1500W RMS at 1 ohm. It delivers 600W at 4 ohms and 1200W at 2 ohms, with a Linkwitz-Riley low-pass crossover variable between 60 Hz and 120 Hz. ParaBASS contouring, Spike Mode, and Valet Mode are built in, and it is compliant with start-stop systems and electric vehicles up to 17V.
Who it suits
It suits enthusiasts building a dedicated subwoofer channel in a car or SUV, where high output, clean signal handling, and thermal stability matter. Valet Mode limits volume to 25%, which is useful if others drive the vehicle. Those needing less power may prefer the Altitude A800.1.
Our tech experts advise
The A1500.1 measures 318 mm wide, 170 mm deep, and 53 mm tall, so check your boot space before fitting. If your factory head unit lacks RCA outputs, an AudioControl LC2i or LC6i line output converter will feed the amplifier a clean signal. Car audio installation is priced per vehicle; contact our Nottingham team to discuss fitting.
