4-Channel 90-Watt Amplifier

The WUQ Kicker 46CXA3604 is a 4-channel full-range car amplifier delivering 90 watts per channel. It uses Class A/B power circuitry and suits drivers who want a flexible upgrade for factory or aftermarket speaker systems. Buyers needing more channels or higher per-channel output should look elsewhere.

Check Battery Voltage And Speaker Inputs

Verify that your vehicle electrical system can supply at least nine volts under load, as the amp operates from nine to 40 volts. Confirm whether you will connect speaker-level signals up to 400 watts or line-level RCA outputs from the head unit. Ensure you have space for either vertical or horizontal mounting orientation.

Mounting Hardware And Signal Flexibility Included

The box supplies both vertical and horizontal mounting brackets so you can choose the install style that fits your vehicle. A variable 12dB crossover and 6dB KickEQ bass boost let you shape the frequency response. The amp also accepts up to 40 volts of speaker-level input, removing the need for a separate line-output converter in many systems.

Questions about this item

What mounting hardware is included with the Kicker 46CXA3604 and do I need to buy any brackets separately?

The amp ships with both vertical and horizontal mounting hardware so you can choose the install orientation without extra parts.

Should I choose the 4-channel 90-watt version or a different CX-Series model for my system?

This 46CXA3604 delivers 90 watts across four channels; select it when you need full-range power for front and rear speakers rather than a mono subwoofer amp.

How does the 90-watt per channel rating hold up when the amp is running on a typical 12-volt car battery?

The amplifier operates from as low as nine volts up to 40 volts, so it maintains its rated output across normal vehicle electrical conditions.
