HCP 4 is an amplifier designed to reproduce any musical genres with four separate channels for multiple configurations. Pre-amplified (Pre-In) inputs and high-level (Speaker-In) inputs allow for connection with any head units. Built to work both in mono, as part of a three-channel system with sub and front, and in stereo for a powerful two-channel system, HCP 4 is a unique model in terms of versatility!


All the Hertz Compact Power amplifiers are assembled with high-quality components and feature a complete and by-passable crossover system. The dissipation system is optimized with the heat being transferred to the heat sink and then dissipated through the sides of the amplifier.

Using the optional HRC accessory (Hertz Remote Control), HCP 4D offers the ability to remote control the subwoofer volume with extreme preciseness.

Features

  • Compact design built from an extruded aluminum heatsink with the top side ensuring effective transfer of the heat generated by the power electronic components.
  • Special balanced input circuitry to reject electromagnetic disturbances present on the Pre-amplified or Speaker level inputs.
  • Input featuring both Speaker-In (OEM radio) and RCA-In (Aftermarket radio) inputs.
  • Selectable ART, Automatic Remote Turn-On/Off function, automatically turns on and off the amplifier when the OEM radio turns on and off (available on Speaker-In only).
  • Power supply stage featuring multiple winding transformer, Low-ESR 105°C capacitors, D-Class 2 ? stable.
  • Pre-out, also available when using Speaker level inputs.
  • Mono operation mode (selectable) to realize a sub + front three-channel system, or a powerful two-channel system.
  • Bass Boost (50 Hz) selectable to 12 dB, to increase the subwoofer punch.
  • Lo-Pass and Hi-Pass 12 dB adjustable (50 Hz to 3200 Hz) filters, providing the ability to realize a front + rear system, a multichannel woofer + tweeter system or a powerful sub + front system.
  • Selectable full range power outputs.

Amazon Essentials Women's High Stretch Jeans
Size: 14, Color: Iced Blue Light Wash
Amazon Essentials Women's High Stretch Jeans receives positive reviews from me for their significant stretch, comfort, and flattering fit. The jeans are great for everyday wear, they feel soft and thick yet move well. Although some folks find sizing inconsistent, occasionally needing to size up or experiencing a slightly odd fit in certain areas. They're praised for looking good, offering good value, and being versatile enough for various occasions. Sizing can be hit-or-miss for some, but not for me.

These Are NOT Skinny Jeans.
Size: 18, Color: Medium Blue
Unfortunately, I'm having to return mine. I purchased these expecting to receive skinny jeans and these are not skinny jeans. These are a relaxed fit, straight leg jean. I'm not too sure about the stretch because they were so big in the leg, I couldn't really tell how well they do stretch. They feel like a nice quality jean other than the fit and they're comfortable around the waist.

Weird garbage
Size: 12 Long, Color: Iced Blue Light Wash
Very strange fit, saw the reviews about weird fit but so many others said great fit so that's on me. Got them for under 10 bucks so hard to complain..... however..... Got 12 Long. They are at least a size too big but I generally do that to accommodate shrinking especially length. On what planet these would be considered long I dunno. I'm only 5'8". If you pull them up to where crotch is not sagging, barely to my ankles. Almost long enough if you want the crotch to droop several inches. Fit loose but comfortable in butt and thighs. The waist however is about 4 inches too big and gaps horribly. Almost like waist is actually wider than hips. Strange. Not skinny cut except for right at ankle. The left leg inseam is cut horribly crooked and runs down almost front of leg so altering them is not worth the trouble. They are fairly thick and do stretch, like the denim wash very much. So disappointed. So the great deal I thought I was getting was garbage . Should have know for that price they were unloading their trash

Perfect fit for 5'10
Size: 10 Long, Color: White
White jeans size 10 long fit perfectly. Im 5'10 130 pounds Always have trouble with length and overall fit. These were on sale for less than 11$! Material has some stretch, not too much. I'm going to hang to dry don't want any shrinkage. Fit is less tight than an earlier version of these jeans.
