The Skar Audio SKv2-4500.1D is the flagship amplifier of the brand and is the most powerful amplifier we have ever designed. Engineered for the most serious audiophiles, the SKv2 product lineup is built for competition and will provide extremely high levels of power output. These amplifiers utilize a heavy duty aluminum heat sink, which when combined with the advanced internal circuitry design, allow them to operate cooler for maximum efficiency. In addition to being 1 ohm stable, the SKv2 series are conservatively rated, and will outperform others in their class with ease. Furthermore, these amplifiers all feature 4-Way protection circuitry, which allows the user to push them to their limits, but all while having the peace of mind that the amplifier will protect itself to ensure for long term reliability and use.

The Skar Audio SKv2-4500.1D is the most powerful monoblock subwoofer amplifier we have ever built, and is for use in applications where the highest levels of power and performance is required. Stable at 1 ohm, and featuring high-speed MOSFET power supplies, this amplifier is capable of extreme levels of power output for extended periods of time. For maximum current flow and sustained power output, the SKv2-4500.1D utilizes dual over sized 1/0 gauge power and ground input terminals. The advanced heat sink design allows for maximum heat dissipation and the 4-way protection circuitry will keep this amplifier safe providing long term reliability.

Ordered this Amp on back order and it still got delivered pretty quick. Skar audio is definitely doing a great job for there customers.

Bad ass

I have this beast on 4 zvx 8s d2 wired to 1ohm.. and it’s literally beating my truck apart.. I couldn’t be happier.

Non stop power amazing amplifiers

After year of playing my 2 SKv2 4500 on 4 18" Skar TXLs, I'm still impressed. This is the first time I didn't upgrade for the next season.

Excellent powerhouse.

This amplifier is an absolute behemoth. Worth literally every single penny. I have two of these 4500.1s on four Skar TXL 15s walled off in a Charger. Lets just say we like jello. Only thing id say is to make power from these savages, you need batteries. I have six Kinetik 2000s and its barely enough. They draw alot of power therefore you need a big reserve. But if you have it, I promise it will give you what youre craving. I need two more batteries to make it push its full potential. Actually if you have one big lithium I think it would be just fine. Go on. Get one.....get two.....

Under rated.

This monster is a power house so connect with caution because it will push anything you connect to the max and beyond.
