Frequently Asked Questions – 4-Channel Amplifiers

How do I choose a 4-channel amplifier for my car?

The choice depends on your speakers and your use case. For a 2-way front/rear kit, a classic 4-channel amplifier is sufficient. If you want to add a subwoofer, opt for a bridgeable model (3 channels). Our team can advise you via the website chat.

What power should I choose for a 4-channel amplifier?
