Install went great but when I higher the volume the bass shuts off then on then so forth and so on. I’m using a ground shaker behind the seat box. I also used the aftermarket plug in play for after market amps. So I just decided to upgrade my bass only on my Sony system. I hope this helps others wanting to upgrade from stock.

I needed to remove the under steering wheel dash panel to make the wiring easy.Ģ) Punch some quality Crutchfield 0/1 power wire through the driver footwell grommet to the battery (+) and route that along the left side sill to the rear of the truck.ģ) I put a power distribution block in back of the rear seats to power both amps.Ĥ) Main left/right/front/back RCAs ran to Kenwood amp and hooked up in bridged configuration as well as remote power turnon from PlugNPlay unit.ĥ) I tapped into the speaker wire harness coming out of the Sony amp mounted at the back wall of the cab. From there I ran a USB wire to program it, a remote turnon wire for the amps and 6 nice Crutchfield RCAs (set of 4 and set of 2) from that unit around the left of the dash and inside the trim piece along lower left center console and to the back of truck.

I can easily upgrade from here if I desire, but to my ears it all sounds great as is. One of the goals was to save money by using bang for the buck components. I thought I'd share my choices and how I did it, there doesn't seem to be a single place to look that has all the information.

Water is responsible for 60 to 65% of body weight among males and 50% among females.All of the trace elements such as iron, zinc, copper and selenium make up less than 10 grams of the human body.The elements in the human body are distributed as water, carbohydrates, fats, protein, hydroxyl-apatite (in bones) along with minerals and DNA.There are 60 identifiable chemical elements present in the human body and of these only around 25 are required for life and good health.

This chapter introduces the principle of the ejector, basic ejector cycle, solar-driven ejector system and its operating. The continuous developments in solar collector technology open the way to the effective utilization of solar energy to power the ejector systems and utilization of environmental friendly refrigerants is also the major concern. Although they have a relatively low coefficient of performance compared to air-conditioning systems using mechanical compressors, the ejector cooling technologies have attracted extensive attentions with ever-increasing awareness and pressures for protecting the environment and have achieved significant improvement in coefficient of performance as compared to other systems. The system could be manufactured at relatively low cost, since inexpensive construction materials may be used. In addition, it has the potential of long life and, unlike vapour-compression systems, produces no noise or vibration. The ejector system has very few moving parts and so is simple in design. An ejector system basically consists of a generator, evaporator, condenser, ejector, expansion valve, and a pump. An ejector heat pump is a heat-operated cycle capable of utilizing solar energy, waste energy, natural gas or hybrid sources (e.g. Ejector refrigeration is one of the most promising technologies because of its relative simplicity and low capital cost when compared to an absorption refrigerator. Using low-grade thermal energy instead of electricity to operate a refrigeration system can have important environmental benefits, especially when it is powered by a renewable energy source. |
