Watts of the kac 9020 - Car Audio & Video

The KAC-624 is a 40 watt x2 @ 4 ohm RMS amp. 55 watt x2 @ 2ohm. 110 watt x 1 Bridged I assume at 4 ohm. Manual does not specify. It can run 2 ohm in stereo mode but is unclear on mono impedance requirement. It can run 4 ohm mono at 110 watt but at 2 ohm?

Kenwood KAC-9104D

Product Features

• Mono subwoofer amplifier
• 500 watts RMS x 1 at 4 ohms (900 watts x 1 at 2 ohms)
• Variable low-pass filter (50-200 Hz at 24 dB per octave)
• Bass boost (0-18 dB at 40 Hz )
• Subsonic filter (15/25 Hz, 18 dB/octave )

This amp is stable down to 4 ohms bridged at 120 Watts or 2 ohms stereo at 60 Watts X 2. If you are going with the bridged mono hookup just make sure the impedance of your subwoofer is no less than 4 ohms. A good rule of thumb is to be at least double of what your amps rated output power is. So if your amp can put out 120 Watts into 4 ohms then get at least a 240 watt subwoofer.


Do not exceed the rated load for your amp, you will damage it. Here is the datasheet for your amplifier

turn down your gain control.

80 Watts x 4 + 240 Watts x 1 It all depends on how you have it hooked up. Let me know if you need additional information on this.
Thanks

is the amp 2 ohm stable? does the amp have enough watts to support the rms of the sub

Power control wire - tells the amp to turn on, usually connected to the blue/white or blue wire when blue/white is not present on aftermarket radios. On factory systems you usually want to hook up this connector to an acc source on the car

Hi and welcome to FixYa,

To my understanding, a Kenwood KAC-628 is rated with max power of 100 watts X 2 at 4 ohms per channel. Incidentally, it is bridgeable resulting to 300watts X 1.

Good luck and thank you for asking FixYa.

150/ch into 4 ohms
230/ch into 2 ohms

Spec Sheet

If the KAC-7252 is to be bridged, the operation mode switch on the top of the amp is set to mono. When switched to Mono, the signal from the left channel input only is used. Bridging creates 4 times as much power so the KAC-7252 delivers 170 Watts per channel so that 340 watts total so that value 340 is multiplied by 4 and that gives you 1360 watts of power. so it will drive them.
