Doesn't it have 3 cylinders? 1 for tilt and 2 for trim?

This diagram looks like it is showing a head unit with line outputs (like preamp outputs) for the main amp(s) and sub. With a separate sub amp, there is usually an electronic crossover involved which splits the audio so everything from mid base and up goes to the main speakers and only low base goes to the sub. If the receiver has actual speaker outputs that go to the power amps, the power amps must be able to accommodate that type of input. In this type of system, the crossover is usually in the 4 channel amp. If you add two speakers to the front channels you will be lowering the load impedance on those channels. If the amp is not rated to operate at the lower impedance, you could blow the amp. When you wire two speakers in parallel like in the diagram Chas0218 posted, the load impedance on the amp will be half that of one of the speakers. If both speakers are 8 ohms, the impedance will be 4 ohms. Most mobile audio systems are rated to handle that and the power output will be higher with a 4 ohm load. But many of the speakers are 4 ohms and if you put two 4 ohm speakers in parallel, the load on the amp will be 2 ohms which may overload, overheat and possibly burn out the amp. You must check the specification for the minimum load impedance rating of the amp. Funny it doesn't show a power lead going to the receiver. I think each electronic component should have it's own fuse also.

I am thinking about it in relation to Waneta Lake in particular. The lake is already eutrophic. There is a golf course and dairy farm overlooking the lake, from which there is probably a considerable amount of nutrient runoff. There is also no sewage system so there is probably a lot or nutrients leaching from septic systems. They have been treating the lake with herbicides for quite a number of years now. When weeds are killed off, the nutrients (phosphors and nitrates) from the weeds go to the bottom of the lake (so they stay in the lake) and the decay of the weeds depletes oxygen. Those nutrients help feed the growth of algae which in turn creates toxins as well as cause further depletion of oxygen. Fish need oxygen to survive. The lake becomes an algae factory. Also, in the last two years there has been substantial heavy summer rains which may have caused more nutrient runoff than usual from the golf course and the farm to help feed the algae factory. There is very little runoff control in the heavy rainstorms and there is heavy runoff all around straight into the lake. So they probably believe they are improving the lake by using herbicide but I wonder if they are actually accelerating the eutrophication of the lake. One of the latest things I heard is that they want to put a bubbler system in the north end of the lake to help raise the oxygen levels. If they hadn't killed off most of the weeds in the lake, there wouldn't be as much of a problem with low oxygen. They would probably be better off working at reducing runoff of nutrients from surrounding land and making plans to install a sewer system and sewage treatment facility. They could probably get State and Federal funding toward these things.

Eutrophication is a very interesting and important topic and I am glad it was brought up because it has led me to further exploration of the problem. It is however, off topic for this string. I do however, think it deserves it's own discussion. I am now wondering if the herbicide treatments at Waneta Lake are just treating a symptom of eutrophication and at the same time exasperating the problem which may have the effect of accelerating the demise of the lake. http://www.nature.com/scitable/knowledge/library/eutrophication-causes-consequences-and-controls-in-aquatic-102364466

Thanks for posting this. It is thought provoking. Just imagine the effect on the smaller lakes. With some it seems clearly visible. But I also wonder if this is something that can occour naturally, depending on the surrounding landscape. I have commonly heard that dairy farm runoff is a serious problem at some lakes.

I am not a perch fisherman. I can say that I love a good perch fry (or walleye). But I don't know anything about quantity or quality of perch fisheries in various waters. If through studies of a fishery over multiple years, it is determined that there is a serious and continuous depletion of the population or size or a serious problem of disease, then the DEC will consider possible actions including changes in regulations. But they will not act without reliable data. If a concern is raised the first thing they will do is work to gather reliable data. If a group of citizens have a concern they need to first bring their concern to the DEC and fisheries management community so that a proper assessment can be made through collection of reliable data. You may even find out that the situation is already being monitored. The key is to start with the facts or get the facts and go from there. There can always be, and almost always is, multiple factors involved with changes in fish populations. Solutions also have to be practical. There can be other influences that have nothing to do with the health of the fishery. Influences such as local interests, selfishness, commerce, tax revenue and pressure from other influential groups such as tournament sanctioning groups and tackle industry. There seems to be many who are concerned about bass but there is so much influence from various groups and so much revenue (and tax) generated from bass fishing related activities, they seem to be reluctant to make any regulation changes. There are many who feel that the early catch and release season is severely hampering spawning activities. I really don't know if they are taking a serious look at these concerns. There may be too many powerful political and commercial influences so that nothing will be done until there are dire consequences. The DEC is trying to simplify the regulations and are trying to keep special regulations to a minimum so they might not even want to consider any new special regulations for perch in certain waters or regions. If there is a problem with a particular body of water being over fished, you can always start a group of concerned fisherman to advocate for more conservative practices. That is what catch and release is all about. You could try to encourage fisherman to only catch what they need or what is legal if you want your children and grandchildren to have fish to catch. Regulations may help, but public conscience can go a long way too. Act for the better good of the fishery. Unfortunately there will always be those who are selfish and even with regulations in place there will never be enough officers to enforce them everywhere.

You will have to find a way. I don't know what is involved in removing the padded panel and if there is metal behind it, that won't do you any good. If the panel below, that the connector is in, is attached with pop rivets, you might have to drill them out and then replace them when you are done. You should use aluminum pop rivets. It is best if the pin is aluminum also. Herb's Fastener Supply or Hewes Fasteners in Rochester should have them so you can get the right diameter and length.

For the bow mount, if the panel that the power connector is mounted to is in the way, you will have to remove it. Then you will have to drill the holes from the top and install bolts from top and reach under to install washers and nuts. Stainless hardware and nylock nuts are appropriate. If the bow panel is not sturdy enough, you may have to install something under the panel to reinforce it, such as an aluminum (1/4 inch) or plywood plate. But since you have a connector for a bow mount and battery compartments for it, the bow is probably already sturdy enough. For the wire to the downriggers, use marine grade wire (it is more resistant to UV, moisture, corrosion and vibration than automotive wire) and make sure the wire gauge is heavy enough to carry the current demand. Keep in mind that the longer the wires, the heavier the gauge must be. Google "12 volt system wire gauge chart". You must have circuit breakers of the proper rating close to the battery.

It might be just some jokers trying to start a riot for the hell of it.
