Our take on the Jensen JA4CH 4-Channel Class-D Car Audio Amplifier

The Jensen JA4CH is a compact Class-D four-channel car amplifier rated at 80 watts RMS per channel at 4 ohms, with bridged output up to 240 watts RMS and a 1000-watt peak figure. It runs cool and draws less current than older Class-AB designs, which makes it easier to install in tight spaces and in vehicles with modest charging systems. Selectable high-pass, low-pass and full-range crossovers plus a variable 45 Hz bass boost let you tune front speakers, subs or a mixed system without extra processors. It is a budget-friendly way into four-channel power, but it sits below premium brands on clean output and build refinement.

Questions and answers

Is 80 watts RMS per channel enough?
It is enough for most factory-replacement speakers and moderate-volume listening. Demanding component sets or subwoofers will want more power.
Can I bridge it to run a subwoofer?
Yes. Bridging channels pairs them for up to 240 watts RMS, so you can run two channels to fronts and bridge the other two to a sub.
Does it accept a factory radio?
Yes. It has high-level speaker wire inputs as well as low-level RCA inputs, so it works with stock head units that lack RCA outputs.
What crossovers does it have?
Each channel pair offers selectable high-pass, low-pass or full-range operation, plus a variable bass boost at 45 Hz.
Can I add a second amplifier later?
Yes. RCA pass-through outputs let you feed signal to another amp without running new cables from the head unit.
Is it good for an ATV or golf cart?
Its compact size and low current draw suit small vehicles, but check that your charging system can handle the load.
