SKv2-4500.1D | 4,500 Watt Monoblock Car Amplifier

MSRP: $ 1,499.99

  • The Skar Audio SKv2-4500.1D is a competition grade monoblock class D subwoofer amplifier that was designed to deliver unequivocal performance and power output. As a part of the flagship SKv2 series of amplifiers from Skar Audio, this model utilizes only the highest quality internal components and features advanced engineering enhancements that allow it to outperform anything else on the market in its power class.

    Whether you are competing in the SPL lanes, or looking for the absolute best amplifier to power your "daily driver" audio system, look no further - this is the amplifier for you. The SKv2-4500.1D is conservatively rated at 4,500 watts RMS power, and at max power output can produce more than an astonishing 7,400 watts. In addition to its extreme performance capabilities, this amplifier features an advanced heatsink design that allows for maximum cooling, as well as 4-way protection circuitry, enabling the amplifier to operate efficiently at peak output levels for hours on end.

    Furthermore, you'll have full reign over your amplifier with the built-in user control panel, featuring variable adjustment tunings for gain level, subsonic filter, bass boost, low-pass filter, and phase control. Versatility is key, and so you have the ability with the SKv2-4500.1D to run them strapped if desired, which is unique to our SKv2 series of amplifiers. In addition to all the above features, it also has both RCA inputs and outputs so that you can easily daisy chain multiple amplifiers together, and utilizes two sets of 1/0-gauge power and ground input terminals (2 of each) which allow for maximum current flow and therefore higher power output.

    RMS Power @ 1 Ω 4,500W x 1 Ch (14.4v)
    Peak Power @ 1 Ω 7,400W x 1 Ch (14.4v)
    Power & Ground Input Size 1/0 Gauge

Haven't had any problems with my new amp

I had one last these and it blew after like a week but skar was very quick with the warranty process and got me my replacement back to me after about a week and a half and the new one has had 0 issues after a couple months

Super banging

Wish only I had gotten 1 ohm subs to use more of this amp but sounds good on these ZVX 12 DV2ohm better get a good box when you have this and be able to supply enough power with high output alternator

Updated review!!!

The last review I did my 4500 wasn’t installed, It’s now installed and it’s a monster!!!

Have all skar in 4 vehicles going on 5

I originally had 1 zvx 12 2ohm. Bought 2 1ohm subs and them bought my wife a zvx15 2ohm. Wish I went with 15s . But I took to long building the box. I'm a week passed the return date! But I did have the rp2000.1d.
Bought the sk4500 for my 12s and a sk3500 for the wife. She has the sdr12s bundle in her other vehicle along with all the 6x9 and 6x8s. I'm gonna see if I can sell the subs at a loss just to get 15s.

Awesome quality sub and amp

I'm digging the quality of the subs and amp. I can't wait to install the new setup. I have already upgraded the big 3 and alternator. Next up is to install the subwoofer and amp and set the frequency/gains properly to hear the power.
