You can easily connect 4 speakers to a 2 channel amplifier just by keeping in mind the impedance of speakers and dividing the power equally to both the channels. There are both methods available to connect 4 speakers i.e series and parallel.
Generally you should pick an amplifier that can deliver power equal to twice the speaker's program/continuous power rating. This means that a speaker with a “nominal impedance” of 8 ohms and a program rating of 350 watts will require an amplifier that can produce 700 watts into an 8 ohm load.
All the difference is about the number of the channel which connects with the number of speakers or subwoofers. A 2 channel amp can join with fewer speakers whereas a 4-channel or more-channel can connect with more speakers or more subs.
A 2-channel amplifier will be the practical solution when you only need to power a single pair of speakers. But if you like rear-fill sound in your car and want to retain front-to-rear fade control, get a 4-channel amp — one channel for each speaker.
You can connect 6 speakers to 4 channel amp either in series or parallel. Both have their advantages as well as disadvantages. The choice will be yours. Suppose you have 4-ohm speakers that people purchase mostly.
Yes, bridging is how it has to be done-if your amp has that option, hopefully. stop telling to bridge without knowing the subs, if it is a dual 4 ohm sub then no, you will not bridge, only if it is a single 4 or a dual 2 ohm sub can you bridge .
Do you want to connect 6 speakers with only 2 channel amp? Don't worry, you can do this.
If you're looking simply for more power for your front and rear speakers, a 4-channel amplifier is the way to go. 50 watts per channel amplifiers work well for most people, producing plenty of volume in most vehicles.
By doing so, class AB amplifiers can keep a higher level of audio fidelity closer to class A amplifiers, while staying cooler and more efficient like a class B. Class D amplifiers take it a step further and they are even more efficient, and less hot, than their AB counterparts.
- Alpine MRV-F300 – Great sound, quality, and compact design.
- JL Audio RB XD400/4v2 – Music the way it's supposed to be heard + modern amp tech & features.
- Rockford Fosgate Punch P400X4 – Great sound in a small package – plus cool set-up features built in.
A 6 channel amp would be the most straightforward thing to do - but depending on what the speakers are and where they are, you have a lot of options. You might even want to run one pair off the head unit itself and then just use a 4 channel amp.
However since subwoofers primarily reproduce low frequencies, and with the incorporation of low pass crossover filters, this distortion is minimized and is the reason why Class D amps are an excellent solution for subwoofer amplification.
ONLY OTHER LANZAR AMP SERIES worth while is the VIBE series (1200d, 1800d). they do rated power and are fairly efficent as far as heat goes. you can beat the hell out of them and they barely heat up, even off a not so great electrical. Lanzar IS made by the same manufacture as legacy, plye, pyramid,and pyle pro.

Things to know about Bridging An AmpThis is because the power of the first channel goes into the second channel before going into the speaker. Extra power to the speaker will not make it play louder or do anything else that might be positive. Instead, like the amp, extra power to the speaker will damage it.
Using the negative signal of one channel with the positive signal of the other channel effectively doubles what each channel alone could put out through a 2-ohm load. Usually, this is the maximum wattage the amp can put out. So, when you bridge your amplifier, you're also optimizing your system's power potential.
He wanted to bridge 4 channel amp into 1 channel. It is not possible. 4 will become 2, and 2 channel can become 1.
The kind of resistance that the sub has will determine the loudness and quality of bass you'll get. Basically, a 2 ohm subwoofer demands less power from the amp and tends to deliver louder bass. On the contrary, a 4 ohm subwoofer will demand more power from the amp and deliver less loud but higher quality bass.
Yes it is possible to do, but it can and the eventually will fry your head unit if it is can't handle it. Plus the gain in a head unit will be very minimal. Most head units run 4 channels at 20watts peak, about 10-12rms. Bridging will give you possibly 35watts out of the two channels and about 15watts rms.
A mono block amplifier has only 1 channel and cannot be bridged. The 2 outputs of a mono block amplifier are there to easily connect multiple subwoofers. If you are not sure whether your amp is a mono block or a multi-channel model, look at the speaker terminals.
Amplifier BridgingBridging an amplifier refers to the process of combining two of four channels into one or two channels with half the ohms. The technique has become very popular among many car owners because it allows amplifiers to send out a more powerful mono signal to the subwoofer or speakers.
Two speakers in series will sound a little quieter than a single speaker, for the same amplifier setting, but not very much. Although on paper the total power is halved, the ear is very non-linear to changes of level, and it will sound 'almost as loud', not 'half as loud'.
resistance doesn't affect sound quality. Like Blaine said, 4 ohms is better, but usually not enough to justify 4 ohm over 1 ohm for most people. There's so other factors to worry about in a system before worrying about which ohm load sounds better.
Your amp needs to have more wattage than your speakers, otherwise you risk blowing both. Your amp needs to have more wattage than your speakers, otherwise you risk blowing both.
The great news is that generally, car tweeters with crossovers are fairly easy to connect to amp in your current (or new) mobile audio system. Most of today's 2 and 4 channel car amp products can handle both a 4 ohm full-range speaker and a 4Ω tweeter connected in parallel at the same time.
Most mono amps only "support" about 15hz to 200hz and anything above it doesn't handle, if that's the case then you can't use it. A sub specific amp generally won't work with speakers. It'll "handle" it. There's just a lot of high frequency distortion so anything above mid-bass sounds terrible.
