 A word of advice bridging can be tricky.

Not all amplifiers can be bridged, and not all bridgeable amps work the same.

A few features to look out for are


Almost all quality amps will be bridgeable, which means you can add more amps to upsurge power supply. The more amplifiers, the more speakers and sub-woofers you can have.

Low-Pass Filter

Very few amplifiers don’t have low-pass filters that will avert higher frequencies from getting to the speakers and sub-woofers

High-Pass Filter

High-pass filters work in combination with the low-pass screen, working oppositely than a low-pass filter by preventing lower rates from getting to the speakers or subwoofers.

Band-Pass Filter

Band-pass filters work in conjunction with both high-pass and low-pass filters to create a steady frequency.

Mono Channel Amplifiers

Monoblock or one-channel amps are easy to use and characteristically only support a small set of speakers or one small sub-woofer. They don’t usually work for all-around car audio systems. Yes, they are affordable, but they don’t offer the power you may require.

Multi-Channel Amplifiers

The multi-channel amp can range from 2 to 6 channels, with 4-channels being your most used model. The number of channels allows connecting to larger speakers or sub-woofer. If you are thinking about adding sub-woofers, it is best to have a 5- or 6-channel amplifier.

Enjoy “Jamming” to your favorite song!!
