Power on amp switch off when base is turned up

The Kenwood KAC-7252 and KAC-9104D are both great amps, but they have different strengths and weaknesses. The KAC-7252 is a 5-channel amp that can output 75 watts per channel at 4 ohms. It also has a built-in crossover and time alignment, which can be helpful for getting the most out of your woofers. The KAC-9104D is a 4-channel amp that can output 100 watts per channel at 4 ohms. It also has a built-in subwoofer output, which can be used to power a separate subwoofer.
If you are looking for an amp that can power all of your speakers, the KAC-7252 is a great option. It is also a good choice if you want an amp with built-in crossover and time alignment. However, if you are looking for an amp that can power a subwoofer, the KAC-9104D is a better choice. It is also a good choice if you want an amp with more power output.
Ultimately, the best amp for you will depend on your specific needs and budget. If you are not sure which amp is right for you, it is always a good idea to consult with a professional car audio installer.
Here is a more detailed comparison of the two amps:
Kenwood KAC-7252

• 5-channel amp
• 75 watts per channel at 4 ohms
• Built-in crossover and time alignment
• MSRP: $399

Kenwood KAC-9104D

• 4-channel amp
• 100 watts per channel at 4 ohms
• Built-in subwoofer output
• MSRP: $499

I hope this helps!

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?

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.

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

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.

your amp is blown up

Unfortunately some of these speakers today... DO NOT PERFORM up to peak as they should.The on logical reason for this to be happening it that the speakers are NOT very DURABLE and cannot take constant playing. I would recommend to L7 the can take alot more abuse than your average speakers. Good luck and thanks for using FIX YA

you need to check your wiring and check your rca wires to see if they are giving your amp a signal to put out

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.
