In general, you need one channel for each speaker that you want to amplify. There are also mono amplifiers with a class D rating that are specifically designed to use less power and put out less heat when amplifying subwoofers.
Units that have two, four, or six channels are more versatile. You can use a two-channel amp to power two woofers or two coaxial speakers, or you can bridge it to run a single sub or power two sets of coaxial speakers.
If you want to add a subwoofer and provide more power to your rear full-range speakers, then a four-channel amp will do the job. In that case, you can run each full-range speaker off its own channel, and then bridge the other two to power the sub.
Alternatively, you can power all four coaxial speakers off the same amp, and then install a separate mono amp for the subwoofer. Component systems can be more complicated, and you may end up needing more than one amplifier, external crossovers, and other components.
This will result in better sound than what you would get without the external amp, and it will save you from having to mess around with additional wiring or adapters. With that in mind, taking some measurements before you buy an amp can simplify matters.
Some popular installation locations include:. Checking the measurements of those spaces ahead of time can save a lot of grief down the line. Also keep in mind that you have to provide power to your amplifier, which means you have to run additional wires. You also need to make sure your car's alternator can handle the increased power draw.

Will two pioneer ts-asls4 subs work with an Alpine S-A60M amp? If not then what amp would you suggest? Wondering if this one will be good Boss BE My amp only powers a single 12" sub.
Each sub that blew was bridged at the amp when this occurred. I recently changed the sub to a Power Acoustik GW which is dual voice coil. I have it bridged at the amp and the sub is wired in parallel. It hits loudly and I am satisfied with the sound but after about min my amp goes into power recovery mode. I removed the sub and checked the resistance and both coil read at 4ohm so the sub isn't hurt and tells me the amp just got hot.
What gives? First I was killing subs and now I'm killing the amp?? Any help is appreciated! Both of my subs are rattling, where did I go wrong? RMS power output: watts x 1 chan.

If you want to use your amp in a recording situation, smaller is usually better.
For instance, Jimmy Page used a small watt Supro combo amp in the studio to create the huge guitar sounds on the early Led Zeppelin records. Some guitarists will use multiple amps in the studio and blend their sounds to get the perfect tone. The possibilities are endless. The same pretty much holds true for playing live: Gigantic amps are no longer needed, as most venues use microphones on the amps to better control the sound that the audience hears.
The only real consideration is being able to compete with the natural volume of the drum set. A cab with one or two inch speakers will probably be fine for live shows. For really big venues, a 4x12 cab is sometimes used, especially for heavier bands.
Save the full stack watt amp and multiple cabs for when you hit the big time! The kind of music you want to play will affect what kind of guitar amp you want to buy. A basic understanding of amp tones and effects can help you make your final decision. These controls are usually labeled treble, mid, and bass. These controls help you achieve your desired tone. EQ is an important part of any amp. Most guitar amps will have a gain knob. This controls the amount of distortion in your sound.
For instance, heavy metal and punk bands usually have a thick, distorted tone. Reverb is a standard effect that sounds like an echo in a big empty room. While not every guitar amp features reverb, it can be found on most practice amps. Eventually, though, guitarists may have a need for them. Some amps feature an array of digital on-board effects that you choose from. Many professional players use pedal boards that they customize with several effects pedals.
By having digital effects built into the amp, it allows you to experiment with several effects without having to buy the pedals separately. Another feature that some guitar amps have is the ability to switch between two or three channels that feature different types of sounds. This is usually achieved through the use of a foot switch that allows you to toggle back and forth between the channels. Some single-channel guitar amps also have a foot switch that will turn the effects on and off.
While all these extra features are fun to play with, the overall quality of the guitar amp is a very important consideration. Trusted guitar amp manufacturers such as Fender make great quality amps with a wide range of prices and features. Fender is a GearSelect partner of School of Rock, and we use their amps extensively in our schools and recommend them to our students.
Fender guitar amps are well-built and sound great, which makes practice a breeze. A good practice amp will be able to cover a wide array of musical styles, from metal to country to jazz. This is usually better than being stuck with one sound, and can make practice more fun. There are many different types of guitar amps on the market.
The two main types are tube amps and solid-state amps. Hybrid amps combine tube and solid-state technologies. Tube amps are known for their rich, thick sound and pleasing harmonic distortion. Solid state amps are improving, and some metal guitarists like the quick attack and tight bass of solid-state amps. This makes solid-state amps the better plug-and-play choice for beginners looking for their first guitar amp.
Hybrid amps feature the best parts of tube and solid-state amps together. While some vintage hybrid amps feature tube power sections and solid-state preamps, most modern practice amps have a tube preamp section and a solid-state power amp section. Look for a hybrid guitar amp that features the legendary 12AX7 preamp tubes.
Over the past 25 years, modeling amps have become very popular for beginners and guitar enthusiasts that mostly play at home.
Modeling amps feature the sounds of many amps in one package. This allows them to access hundreds of great tones in a single amp.
