Ruthless Audio 1500.4 4-Channel 1800W Full-Range Car Audio Amplifier Sold by AudioSellerz.com
If you need a serious 4-channel amplifier for mids, highs, mid-bass, or a full active front stage, the Ruthless Audio 1500.4 is built for exactly that kind of system. This Class D full-range 4-channel amplifier is made for loud daily drivers, demo vehicles, pro-audio door builds, motorcycle audio setups, and front-stage systems that need real speaker power with the tuning control to match.

The Ruthless 1500.4 is rated at 250 watts x4 at 4 ohms, 450 watts x4 at 2 ohms, and 900 watts x2 at 4 ohms bridged on 14.4V, giving you the kind of output needed for serious speaker systems. That makes the Ruthless Audio 1500.4 amp a strong fit for active front stages, semi-active front stages, pro audio mids and highs, door speaker builds, and even bridged mid-bass duty when the setup calls for more power per channel pair.
One of the biggest reasons the Ruthless Audio 1500.4 4-channel amplifier stands out is that it gives you real multi-channel power without giving up tuning flexibility. If you are trying to run tweets, mids, and mid-bass with more authority than a basic full-range amp can offer, this amplifier is built for that kind of work. It can anchor the front half of a serious car audio system when paired with the right speakers, wiring, and electrical support.
The Ruthless 1500.4 uses Tiffany-style RCA inputs for clean, solid signal transfer and 1/0 gauge power and ground inputs to support the current draw that comes with a high-output 4-channel amp. It also operates on 8V to 16V, giving it the voltage range needed for real-world systems that may see different charging conditions depending on the build.
This amp also brings strong tuning control to the table. The Ruthless Audio 1500.4 features input sensitivity from 6V to 0.2V, a high-pass filter from 20Hz to 800Hz with an x10 multiplier for 200Hz to 8kHz, and a low-pass filter from 50Hz to 800Hz with an x10 multiplier for 500Hz to 8kHz. That makes it a strong option for mids and highs, front-stage speaker systems, pro audio speaker builds, and active setups where crossover control is a big part of getting the sound right.
A built-in clip light function helps you set gains more accurately and avoid clipping your speakers, which is a useful feature in loud systems where protecting expensive drivers matters. The listed THD at 4 ohms is greater than 0.01, and the recommended fuse is 200A, making it clear this amp is built for real output and should be installed accordingly.
The Ruthless Audio 1500.4 is ideal for a lot of serious speaker builds. It works well in active front stages where you need onboard high-pass and low-pass control for tweets, mids, and mid-bass. It also makes sense for pro audio door builds, motorcycle audio systems, and loud daily or demo builds that need strong 4-channel power without stacking multiple smaller amps. In the right setup, it can even be used for bridged mids or small substage duty when configured as a 2-channel amp at 4 ohms bridged.

I recently had a pair of 1 inch JL audio pillar mount tweeters and you could barely hear him so somebody told me that I should try to purchase a pair of yards so I purchased the 2 inch and put them in the tweeters and you could barely hear him so somebody told me that I should try to purchase a pair of yards so I purchased the 2 inch and put them in the side panels and they were completely day and night. Yours were just outstanding and they were great hands down there’s no comparison to. JL Audio. Yours were the best and I ordered a second set.

Easily the best sub I've ever owned. They make my Avatar's and my HCCA's seem like flea market subs. They play everything and they are accurate while doing it. These subs are spec-damn-tacular!
