Review
The Kenwood KAC-M3004 is a powerful, compact, 4-channel amplifier for your car.
It has happened to all of us that we are on a car trip and suddenly we feel like turning up our radio because a great song appears that we want to hear at full volume.
But we have also had to suffer the terrible “pop-up” or backfire, along with the loss of quality, which suffers the factory radios that come in most cars to turn up the volume.
Forget about this problem with the Kenwood KAC-M3004, you can boost all your music with its 50 watts RMS power per channel. And because it’s so compact, you can fit it almost anywhere without a problem, even on a motorcycle.
Something we have loved is that you can install subs, thanks to its 4 channels.
Another thing that we loved about this amplifier is that it has proved to be very versatile, as it accepts the signal from almost any source. We have tested it with RCA cables, even with the factory stereo radio. Also, it turns on only when it receives a signal, so you don’t need an additional power cable.
Features
Compact and resistant to humidity
The amplifier has a compact construction, which is coated to protect it from moisture and dirt. This allows the Kenwood KAC-M3004 to be used on motorcycles, off-roaders, or marine vehicles (among others).
In the case of using its channels, we will also have to take into account that its RMS output at 4 ohms has a power of 50 W. While at 2 ohms it has a power of 75 W. We will have to choose what type of configuration we want.
Circuit protection
Apart from the coating that covers it with moisture and dirt, it has a thermal protector that turns it off when it gets too hot.
Power on with signal detection
Something very popular and convenient that prevents us from having to use an ignition cable.
Crossover
This amplifier is divided into two parts, A and B (independent. Each can be configured for high-pass or low-pass operation or turned off for full range operation. This is great for different configurations.
Mounting
Can be mounted on an installation plate (5/8″ thick or more).
Box Contents
- 4 channel amplifier with a 30A ATM mini-fuse installed
- 9″ speaker output harness (8-pin Molex plug on one end)
- 4 screws (M4 x 16 mm)
- Two 13.5 ” plastic wire ties
- Self-adhesive transparent plastic protective covers for controls (2 sheets)
- Instruction manual / Warranty card
Controls
Power connections / power control
These are 0.35″ wide screws. We will need a 10 gauge wire (minimum) to provide power and ground.
Power control
This cable has to be connected to the remote power supply when using secondary units. We will not need it if we are using speaker inputs. This controller will be in charge of turning on the amplifier when it detects a signal.
Speaker output
With 8 x 16 gauge wires to connect the speakers to the amplifier. These can be connected to a 4 channel system, a 2 channel high power system, or a 2 channel + subwoofer system.
For installation, we recommend that you follow the manual or a video, as it cost us quite a bit.
Line level inputs
It has two stereo RCA inputs. We can decide to use a factory unit or a unit without preamplifier outputs, but we will have to splice the speaker cables to an RCA plug.
