Alpine 300-Watt RMS Mono Marine-Grade Amplifier @ 2-Ohm or 200-Watt RMS Mono @ 4-Ohm

Get big amp performance in a compact, resilient package. With Alpine’s exclusive technology, Dynamic Peak Power (D.P.P.), the KTA-30MW Weather Resistant Tough Power Pack is sure to deliver powerful bass output for subwoofers used in those open cab vehicles and toys. This small and efficient amplifier can be installed with an aftermarket or factory head unit while adding up to 600 watts of D.P.P. power. Its weather resistance makes the KTA-30MW a good choice for use in exposed installations like side-by-sides, boats, open-top vehicles, and motorcycles saddlebags.

The KTA-30MW is ready for your adventures. It is weather resistant, rated at IP66 for protection again dust ingress and high-pressure water spray.  Its rugged chassis and high-quality waterproof connector can be used in installations where it will be exposed to the outdoor elements.

The KTA-30MW is perfect for when you want to add subwoofer power but don’t have the space for a large amplifier. It is compatible with an aftermarket or factory head unit and provides up to 600 DPP watts to the subwoofer of your choice.

The KTA-30MW features Alpine’s exclusive Dynamic Peak Power (D.P.P.) technology which intelligently adjusts the gain to automatically adapt to musical needs. D.P.P. prevents the amplifier from clipping music signals by supplying up to double the power to support power hungry, rhythmic peaks like a snare drums, trumpets, or high-hat cymbals. During these dynamic musical passages, D.P.P. instantly delivers bursts of power to rise to the peak demands of the music and very quickly rolls back down to maintain its efficiency.

The KTA-30MW measures just 9-3/16” (W) x 1-5/8” (H) x 3-3/4” (D), so its small footprint lets it fit where most amplifiers won’t, like  under the dash or in the glove compartment, installed under the dash of a side-by-side, placed in the saddlebag of a motorcycle, or used in other places where space is an issue.

EXCELLENT FEET MOISTURE PROTECTION
Size: S (up to size 7)-Beige, Size: S (up to size 7)-Beige
Why did you pick this product vs others?: I have burns on my feet and needed something that I could put burn creme on and still walk around in with. I tried other silicone footsie but they would teae really easily. So far these are doing really well for this purpose. They are holding their shape too. The only caution I have is the same with all silicone footsies: They can be slippery on wet floors, so also wear with socks over them. The biggest issues is when they say a size they mean it. The silicone used in these have little give in them, so they won't stretch out and loose their shape. That can be a good thing, or not so good, depending on how well they fit your feet and what your intent is with wearing these. The other issue is if they fit snug around those toes, that tends to be where the first tear in the material will happen. Because of how these are made, the tear is actually more like cracking in the material and once it occurs you won't be able to get much use out of the sock after that. If you are planning to wear them around the house or for long term use, I suggest going up a size or look for the toeless options.

Silicone socks
Size: M (up to size 9)-Beige
The socks are sized large. The quality of the silicone is good. But they slide around on your feet if you try to walk, making them difficult to use and a bit uncomfortable. Unless you are able to sit for long periods of time the likely will not work well. Recommend looking for a better value.
