When your car audio speakers aren't working good while being powered off your stock radio unit, you better hop a nice 4 channel car audio amplifier in. And talking about a 4 channel car audio amplifier that has the capability to go beyond expectations, its the CT Sounds AT-125.4 Class D 4 Channel Car Audio Amplifier; 800W RMS you better look into.

Although most of the car audio amplifiers are class AB but this one is a class-D amplifier with bold outlook and staggering technical specifications. To cover your car audio mids (woofers) and highs (tweets & horns), this 4 channel car amp is a true and bold solution. This amp has got 2 pieces of inline fuses which protects the internal circuits while overloaded/ impedance mismatch. Talking about beauty, this amp has just got it with its LED logo on top and reinforced tiffany style RCAs. You get to place strong and rigid audio push connections with low resistance joints. For those who want some powerful speakers get powered off a powerful amplifier, this amp is the best!
