SUNDOWN AUDIO SFB-1800.5D ( 5 Ch Full Range Amplifier)

Amp creates a lot of noise that plays through channels 1-4, I double checked my whole setup before contacting sundown and was told that this 600$ amp was one of their budget models and it was to be expected. Extremely disappointed with that but noise goes away by lowering gain to almost quiet and cranking head unit up. It bumps well and sounds great otherwise but really disappointed that Sundown (a top tier brand) would consider this normal behavior of any of their amps.

Had this amp over a year already. Running component 6.5s and 6x9s as well as a pair of Alpine Type R 12s at 1ohm . One amp runs the whole system with loads of power. Only downfall is amp does produce some noise at idle. Even with the gains set with a DD-1, Ground loop isolators and a capacitor.

First, JP and the team are awesome! My amp arrived fast, packaging was good with a thank you and a lollipop. Keep up the great customer service! Oh, the amp is a powerhouse. Lovin’ life!

Powerful and great sounding amp!

One amp powers whole system, this all you need,its clean and very efficient.Down4sound youre the best,no sales tax, free shipping and two day delivery.

Quite impressive for the price. Sundown never fails to amaze with their products and Jonathan Price never fails at keeping his word with super quick shipping. Only place I will buy car audio products
