Our take on the Down4Sound JP154 | 1000W RMS Car Audio Amplifier

The Down4Sound JP154 is a Class D four-channel car amplifier rated at 1000W RMS total. It puts out 4 x 150W at 4 ohms, 4 x 250W at 2 ohms, or 2 x 500W bridged at 4 ohms, tested at 14.4V and 1% THD. Adjustable high-pass and low-pass crossovers plus a x1/x10 multiplier let you tune mids, highs and bridged sub duty from one compact chassis. It suits multi-speaker builds that want flexible tuning without a big footprint, and it competes with other compact Class D four-channels on channel count and crossover range rather than raw wattage.

Questions and answers

Is the 1000W rating per channel?
No. It is the total across all four channels. Each channel is 250W at 2 ohms, or 150W at 4 ohms.
Can I bridge it to run a subwoofer?
Yes. Bridging two channels gives 500W at 4 ohms, so one amp can run a sub on two channels and speakers on the other two.
What crossovers does it have?
A high-pass filter from 20Hz to 800Hz with a x1/x10 multiplier reaching 8kHz, and a low-pass filter from 50Hz to 800Hz.
Does it need an external DSP?
Yes, if you want time alignment or per-channel EQ. The JP154 has crossovers and gain but no DSP.
What power supply does it need?
Ratings are taken at 14.4V. Plan on an upgraded alternator and wiring so voltage holds up under load.
How much input voltage does it accept?
Input sensitivity runs from 0.2V to 6V, so it works with most head units and line-output converters.
