The new MB Quart Reference MYKRO amplifiers are
available in a 4-channel, 5-channel, and a monoblock configuration. All of them use Class D technology, and the four and five channel are both full-range Class D amps.

The new MB Quart Reference MYKRO amplifiers are available in a 4-channel, 5-channel, and a monoblock configuration. All of them use Class D technology, and the four and five channel are both full-range Class D amps.

Each amplifier has a Q-Stasis pre-amplifier circuitry stage. This circuitry rejects noise and assures that clean signal is introduced into the amplifier circuitry. The signal that comes into the amplifier from the source unit can vary widely and depending on the length of the RCA cable, there is a nerly certain chance f noise being injected into that signal wire. Signal from a head unit can be as low as 2 volts and as high as 8 volts. It is critical that an amplifier be able to balance this input signal without allowing noise into the circuit. The Q-Stasis Pre Amplifier Stage keeps the signal in balanced, quiet, and ready for the amplification circuit.

These amps are the definite choice for those limited with space in their installation, but still want have a clean, powerful amplifier. The Hybrid Class D topology is designed for a small footprint, but has exceptional sound quality.

Top Locations to Mount a Car Amplifier

There’s no greater accomplishment than installing a sound system on your own. Sometimes you’ll run into road blocks along the way, like finding a location to mount your new amplifier. There are many places that are acceptable to mount an amplifier, and it’s a matter of finding the one the works best for your application.

Underneath the Seat

One of the most common locations to mount an amplifier is underneath a seat. This method will keep your amp out of sight and leave your car looking factory. If you’re installing a 4-channel car amplifier to power your door speakers, by mounting it under your seat you will have a central location to rout all of your speaker wires. Keep in mind you will need to hide any connections that could potentially be kicked or stepped on by passengers.

Trunk or Hatch Area

Another option is to mount the amplifier in your trunk or hatch area. This is most commonly done with subwoofer amplifiers, as it’s easy to keep the length of the speaker wire leading to your subwoofer down to a minimum. Keep in mind if you have a vehicle where you can see into the trunk area, this may not be the best location.

Amplifier Rack

If you’re going for a custom look for your installation you can build what’s called an amp rack. An amplifier rack can be anything that you’ve built to hold one or multiple amps in place. You can mount amplifiers in places like under the rear deck of a sedan, hidden in open cavities of your car or any other place you can think of. If you do build a rack to hide your amplifier, make sure it has lots of ventilation as it will get hot.

Final Tips

If you want to mount a car amplifier to the back of an enclosure, add a rubber gasket wherever you put a screw in. This will reduce vibrations that travel to the amplifier, potentially causing damage. If you decide to mount your amp to the back of a seat, remember to leave a couple of extra inches on each wire in case you need to fold your seat down. Strategize your installation and plan things out before you start screwing things in. You can do it! Let us know where you prefer to mount your amplifiers in the comment section below!

Brief Look at the Basics of How Car Amplifiers Work

At some time you may wonder, how does a car amplifier work?  Car amplifiers enhance the signal that runs through the sound system and plays them through the speakers. There are many confusions and mix-ups about how a car amplifier works.

Car Amplifier Circuit Board

Car Amplifier Circuit Board

First, an electrical signal moves into the amplifier, through a circuit board, and out the other side through the speakers.  The electrical signal may originate from wherever the sound source is, such as the radio or from the CD player. These devices direct a signal to the circuit board.  The circuit board boosts the signal as it moves through the sound system of your car.

A frequently misinterpreted functioning of car amplifiers is their output.  The output of each car amplifier differs and can be determined very easily.  The RMS (root mean square) rating of the amplifier does not tell you very much about the amplifier because most amplifiers will only reach this level for a segment of a second at a time.  Instead, you can calculate the actual output of your amplifier by multiplying the peak output by 0.7 and then subtracting the amp’s announced peak performance number from the number you just calculated.

Another characteristic of the car amplifier that is normally mistaken is the bridging.  An amplifier that is bridged or can be bridged is simply an amplifier that can create one power supply out of the left and right power supplies.  This can significantly boost the power supply to one subwoofer.

When looking at bridgeable amplifiers the term “bridgeable” basically means that the amplifier has the ability to combine the left and the right channel wattage into a single output for one subwoofer. Many amplifiers are not bridgeable either way make sure to read the manufacturer’s recommendation before bridging the channels. To bridge an amplifier, simply place the negative cable of the speaker to the negative terminal of one channel, and the positive cable to the positive of the other. The united power will send the total of both channel’s power to one speaker.

Want to hook up your own subwoofer?

Lately I’ve been doing a lot of research on car audio (being that I am one of the newest team members here at Sonic Electronix) and even though I highly recommend you get this done by a trained professional, there is always an opportunity to learn something new and try it yourself. Stereo systems are at least as simple as most other single accessory electrical systems, but they are still electrical systems. Physically wiring the system is the easiest part of installation. The rest of it is knowing what you’re working with and figuring out what to connect to what and in what way. But once you know what all those numbers and ratings on the amps and speakers mean, the process pretty much explains itself.

First and foremost you need to determine your amplifier’s minimum stable impedance  in ohms of resistance. You’ll typically find the stable impedance rating between 1 ohm for a powerful amp and 5 to 10 ohms for a less powerful one. The lower the amp’s stable ohm rating, the more power it can transmit through a single channel without frying. For this blog, I’m going to explain this if I were using an amplifier with a 2-ohm minimum staple impedance.

Now go ahead and check your subwoofer’s ohms of impedance. This works the same way as the amp does; a massive, powerful subwoofer has large coil windings that provide little resistance to power flow and a smaller speaker provides more resistance. This will determine whether you need to wire the subs in parallel or in series. Compare your amplifier’s ohm rating to the speakers. If the speaker ohm reading is lower than the amp’s, then connecting that single speaker directly to the amp output will fry your amp. You’ll need another speaker and you’ll need to connect the speakers in a series circuit instead of a parallel circuit.

Connect a parallel circuit in just the way you’d think ( positive to positive and negative to negative). As long as none of the speakers in your system have a lower ohm rating than the amp, then you’ll want to connect them directly to the amp terminals. This will give you the best chance at nailing down the ground pounding power you are looking for.

Connect the first part a series circuit by wiring the positive lead of one speaker to the positive terminal on your amp. Connect the negative terminal on that speaker to the positive terminal on the next in your series. If you only need two speakers to meet your amp’s minimum impedance, then connect the negative terminal on the second speaker to the negative terminal on your amp.

Wire as many speakers into the series as you need to meet your amp’s minimum amp impedance. Connect them all positive to negative with the positive and negative terminals on the speakers on the ends of your series connected to the appropriate terminals on your amp.

Now do remember that every car is different, so if you have any questions feel free to contact us here and Sonic Electronix and we’d love to help you out. Of course it’s going to be a little intimidating, but please make sure that you never work on your cars electrical system unless you are absolutely comfortable with it.
