Speakers need not match in size. Feel direct utilizing a similar brand and barbecue plan for each. Trim and join the layout to the mounting surface. Utilize a 5-inch opening saw to cut the fundamental opening. Oval speakers will require a saber saw to cut the oval opening. Then drill every one of the mounting openings. Angle each opening to keep the gelcoat from breaking.
Place the froth gasket on the rear of the speaker, adjusting it to the mounting openings, and connect the speaker wires to the spade fittings in the speaker, ensuring the extremity is right. Slide the speaker into the primary opening and secure it with the mounting screws. Your email address will not be published.

Finally, you connect a wire from the negative lead on speaker 2 back to the negative lead on the amplifier.
The whole thing forms a loop. With this method the resistance increases with each speaker you add. Two 4 Ohm speakers wired this way create 8 Ohms of resistance. The result is basically as follows. If you have a 50 watt channel on the amplifier, the power is divided between the speakers, 25 watts to each. Keep in mind that there is a limit to the level of resistance an amp can handle. In most cases you don't want to exceed 8 Ohms on a channel so generally no more than 2 speakers on one channel.
Parallel This is when you wire the positive and negative leads from each speaker directly back to the positive and negative leads of the same channel on the amplifier.
Interestingly, this has the opposite effect and actually decreases resistance in the channel. Two 4 Ohm speakers wired this way will lower the resistance in the channel to 2 Ohms. If you have a 50 watt channel, each speaker receives 50 watts, essentially doubling the power output.
Again, keep in mind that not all amplifiers are built to successfully do this, so read the documentation for your amplifier. When wiring speakers in parallel you can see the benefit of starting out with speakers of higher resistance such as 8 Ohm speakers over 4 Ohm speakers so that you don't lower the resistance in the channel too much by adding speakers.
On the other hand, if you only want to use four 8 Ohm speakers in your system, you may be better off to wire them in parallel to only 2 channels of your amp, rather than one speaker on each of 4 channels. Using a marine stereo in a backyard or other non-mobile application Many of our customers use our stereos in backyard barbecues, pool and hot tub areas, and other land based outdoor applications.
An important consideration is that all of our stereos are made to run off of a 12 volt marine or car battery so you will need some kind of power adapter in order to power one of our stereos from household current. We sell a high quality 10 amp adapter for this purpose or you can pick one up inexpensively at an electronics store like Radio Shack. The important thing is that the adapter provides enough amperage for the stereo.
Many adapters just don't have enough amps. You will need a minimum of 5 amps to power your stereo adequately. Sometimes people will use a notebook computer adapter because they usually have higher amperage. Power adapters are not waterproof, so they will need to be positioned in an area where they are out of the weather. If necessary, you can run longer wires between the stereo and the adapter in order to position them where you need them.
Use solid core doorbell wire for this purpose which is perfect for low voltage outdoor situations. Our head units are both UV and water resistant.
We offer high-quality marine amplifiers that are water resistant and able to run efficiently off of batteries, so you can keep your music playing longer. Wire and Cables. Proper wiring is a crucial component of your complete sound system. We install systems that look as good as they sound. In addition to sound systems, we offer marine lighting installation. Add LED color lighting to your deck, or custom accent lighting. We can also amp up the look of your sound system with trim ring lighting for your speakers, and other custom touches.
