Full Range Means All Systems With DS18’s FRP-2.5K!

Its variable crossover filters allow you to fine-tune your sound for optimal performance. Depending on your Band-Pass Adjustments, this Full-Range Amplifier can be used for Bass, Mids, or Highs. Micro digital design maximizes the FRP-2.5K’s power output and efficiency.

DS18’s FRP-2.5K was built for durability and performance. The protective coating on the PCB prevents moisture corrosion and bonded components provide extra vibration protection. This means you can enjoy high-quality sound even in harsh conditions.

Its bass boost feature enhances your low-end frequencies for a richer, more powerful sound. The bass knob also comes with power and clip indicators: with short circuit thermal, DC offset, and high/low voltage protection - your amplifier and vehicle are safeguarded against the most common problems in car audio.

DS18’s FRP-2.5K outputs 700W RMS @ 4-Ohm; 1300W RMS @ 2-Ohm; 2500W RMS @ 1-Ohm; and 2800W RMS @ 1-Ohm (BURST) – perfect power settings to supercharge any vehicle.

Thanks to its compact size, Tiffany RCA Terminals, and coming in three different colors (blue, titanium, or red) the FRP-2.5K fits in any system.

Upgrade with DS18’s FRP-2.5K and bring power to any system.

Great no shows for people with larger feet
Size: Large, Color: (001) Black / Black / Castlerock
Some of my favorite socks!! Great quality, fit, and material. I love that they don't slip down in my shoes, especially considering I have larger feet. I also love that Under Armour offers larger sizes in their socks considering everyone in our household has much larger feet than others.

Best liner socks EVER
Size: Medium, Color: (348) Silica Green / Silica Green / Hydro Green
I have them in every color and used to get them from Sams, but they stopped selling them and I was lucky to find them on Amazon. Got all colors again. They stay, it's all I'm gonna say! And don't show in any of my tennis shoes. Absolutely love them and wear them until they get holes. They last a LONG time too. They're on the thin side and my foot loves them because they tend to get hot. There's no shrinking, they wash great with exception of the white ones I couldn't manage to keep white - they turned a bit greyish.

Great socks
Size: Medium, Color: Pink - 647
Well-made and comfortable to wear. Great for golf and other outdoor activities. Like them because they do not show above shoes.

These ACTUALLY stay put all day long - I was skeptical, but am so glad I took a chance on these
Size: Medium, Color: (014) Halo Gray / Halo Gray / Castlerock
I was so skeptical about whether these would stay on my feet all day without sliding down into my shoe - I’ve tried so many socks in the past with the silicone strip on the heel which failed. I’ve owned these for a couple months now and they have never slipped down - they stay put all day! I love the variety of colors to choose from, and the value per pack is great since six pairs come per pack (I thought it was only three when I first purchased and was pleasantly surprised by the additional pairs). They also have perfect thickness - not too warm to wear during the summer months with sneakers; I live in a tropical climate, though, so I’m not sure how they will do in cooler climates. I’ve washed each pair once or twice and the color and quality of the silicone has stayed so far (knock on wood). Overall: high recommend based on my experience so far!
