Car amplifiers are DC devices. They take the DC power from the car battery and convert it into AC power. The AC power is then used to drive the speakers.
Car subwoofers are typically AC, but there are some DC models on the market. AC subwoofers are usually more powerful and have a higher quality sound. DC subwoofers are typically less expensive and are more compact.
If you have a two-channel amplifier, you can wire two speakers to each channel. This gives you four speakers in total, which is the maximum number of speakers that can be safely powered by a two-channel amp. When connecting four speakers to a two-channel amp, it's best to wire two speakers in series to each channel.
No, higher watt does not mean more power.

For a 12 volt application, I bought two of these, one for the negative and the other for the positive. They were simple to install and solidly constructed to withstand the additional torque required for vibration. I expanded the truck with a number of new goods, and it worked well for establishing connections in the right places. I'm coming back.

It is manufactured of a respectable alloy, and the slotting is turned rather than cast, making it precise and having little run-out.If you're running a 4/0 source line like I am, be careful because the single-side has a 4/0 collet that isn't really designed for retention. To prevent the collet from falling out with a live end, you'll need to tighten the living beans out of the retention screw. Collets aren't present in the two smaller apertures, which I wish they were.A single posi-drive screw that is not in any way covered secures the conductor block into the plastic as well. In order to avoid a failure or unintentional grounding, I filled this up with silicone. As a backup plan, I also used some silicone inside the plastic volume to double the conductor's retention. That exposed, charged screw head bothers me; you're just begging for a short.This was one of the few tiny devices I could discover that supported multiple 4/0 out and 4/0 in. To divide my power distribution between the forward auxiliary and rear auxiliary systems, the supply in my case will start off as a 4/0 before splitting into a 4/0 and an 8 gauge. The secondary 4/0 lead will periodically experience up to 75A, while the 8 g lead will occasionally experience up to 35A. My 1000w inverter, secondary lighting systems, UHF radio systems, radar systems, metering, and so on will not all be running at the same time, and that inverter will only be seeing probably somewhere in the realm of 200-300w steady use. I do not expect these loads to be consistent or normal by any means (with some startups around 1500w).ANYWAY, the point is that I have faith in this conductor. Even though I dislike some of the secondary qualities, I can fix them with five minutes on the workbench and make it safer. With the collet attached, do NOT expect this item to tolerate any pulling on the source wire. With a little force, it *will* pull it out without any issues. Put your lines in a good place and secure them with ties.

It is a relief that the ports on this distribution block are true to size because that information frequently gets lost in translation. Actually, a clear plastic top that latches onto the block with the help of four tabs covers it. I actually had to snap the tab off with the use of a thin screwdriver while being careful not to break it because the tabs aren't the simplest to deal with. The distribution block is attached to the transparent plastic base with screws through four holes. The edges of the screws used to fasten down the wires are slightly serrated and have a beveled end, which may or may not be a good thing. If you have something like a 10,000 strand monster cable, those serrations will gnaw into your cable and actually improve your connection. The drawback is that after you detach the cable, some of the strands may break off, and you'll need to cut the cable down to size in order to recover all of the conductors. Each strand in a starting cable made of 110 strands of 2 gauge, as I do, is thicker and less prone to be broken by those serrations. Starter cable can still be used for automobile audio because, despite not being as flexible, it has enough give to withstand road vibrations when stretched out briefly. Overall, this item fit well, served its purpose, and is attractive.

fantastic stuff I wired it with 1 gauge wire. The clear plastic cover for the splitter (which is bent for the wire) may need to be slightly sanded down if the wire shielding is a little thick. In any case, I was pleased with the outcome and will only use this particular product moving forward.

small size, enduring quality, and affordable. A little more depth would be helpful in the pockets.
When choosing a power supply for your amp, you'll need to consider the wattage, voltage, and amperage. The wattage is the most important factor, as this will determine how much power your amp can draw from the power supply. The voltage and amperage are also important, as they'll determine how much power your amp can use.
There are a few ways to increase the amperage on a 12 volt power supply. One way is to increase the voltage. This can be done by adding more batteries in series or by using a higher voltage power supply. Another way to increase the amperage is to decrease the resistance in the circuit. This can be done by using thicker wires or by using a lower resistance load.
If the amp gain is too high, the sound will be distorted. To prevent this, turn the gain knob until the sound is clear.
A 1000 watt car amp will draw approximately 8.3 amps.
A 1200 watt car amplifier typically draws between 10 and 20 amps. The specific current draw will depend on the efficiency of the amplifier and the voltage of the car's electrical system.
How many amps does a 2000 watt amplifier draw? A 2000 watt amplifier will draw approximately 8.3 amps from a standard 120 volt outlet.
