It's entirely possible to use four 70W speakers with a 150W amplifier but the method will depend on the speakers and the amplifier specification. We will assume that the amplifier will deliver up to 150W per channel, so two speakers will be used on each channel.
If the amplifier is rated to drive a 4 ohm load, then two 8 ohm speakers can be wired in parallel and connected. In this instance, take care NOT to drive the amplifier too hard. It will overdrive the speakers at about the same time that it will begin to show a distorted output. This is a condition that can easily damage speakers so be very conservative with the volume control.
If the speakers are 4 ohm speakers, they can be wired in series to provide a total impedance of 8 ohms. If the amplifier is rated to deliver 150W into 4 ohms, then the total power to the speakers will be lower than to a single speaker. The benefit is that no speaker can be over-driven and there is a good amount of headroom for safety.

How do you match speakers with amplifiers watts ohms max power ect?
You always want to buy speakers rated higher than the max RMS output of the amp. I've blown plenty of speakers in my day as soon as I turned it on.Ohms is just as important. Never connect two or more speakers in parallel. This cuts the ohms to less than half and you will blow the amp if its not designed for it . You can connect speakers in series if you like but this cuts your RMS output to less than half and also could blow the amp. One speaker per channel and keep the gain nob one level below max to be safe.Car amps 4 ohms speakers.House amps 8 ohms unless specified.That answer (above) is not much help, nor true. (I wouldn't trust someone who has blown "plenty of speakers", it sounds like a poke and hope job.) Unfortunately, the correct answer is hard to obtain because the people who sell amplifiers and speakers don't always use the RMS power rating for CONTINUOUS power when describing the components. These manufacturers know that we folks are into POWER and they usually advertise the components "PEAK" power rating. WOO HOO!But bottom line, it's easier to blow the amp with higher rated speakers because the the amp is working too hard to fill that big jug so to speak. The rule is to get an amp with about twiceas much RMS value of wattage at 8 ohms as the speakers RMS value at 8 ohms. You'll need to leave the room because your ears will be throbbing before you'd do any damage to your speakers.But yes, it's always important to follow these steps and be sure to connect your speakers and inputs (mikes, instruments, etc.) first, AND have the power level controls SET LOW, then power up, and then adjust the volumes up until you get your sound right.Connecting speakers in parallel is a whole different topic, but it LOWERS the ohms resistance and yes, it takes lesser wattage to blow them.
What is better 16 ohms speakers or 8 ohms speakers?
It depends on the application. If you have an amp that is stable in 8 ohms per channel, then 8 ohm speakers will work best. However, if you wanted multiple speakers on that channel you could use two 16 ohm speakers.
Is it ok to use an amp rated at 4 Ohms and speakers at 8 ohms and why or why not?
yes you can you will have to wire up the speakers in parallel because with 8ohm it gives too much resistance and the amp will produce unwanted sound i.e. low volume.
If an amplifier is AC 220Watt and 12 DC so up to how many watts or ohms speakers you can use on it?
Your question doesn't fully make sense. Let me see if I can answer part of it. If your amp puts out 220 watts, the speakers should be rated for at least 220w, or they may be destroyed if you turn the amp all the way up. Watts are a measurement of power, in the case of speakers they are rated for how much power (watts) they can handle. Ohms is a different thing altogether. Ohms are a measurement of resistance to electrical flow. Amps are usually rated to work with certain impedance level speakers (4 ohm, 8ohm, 16ohm, etc.) the lower the ohms, the harder the amp works. I know it seems backwards but it isn't. each amp is different so you would have to read the amp's spec sheet to see what they reccomend. I have no idea what you are asking for with the "12 DC" thing.
What should the low pass filter be set to?
If it is a subwoofer amp then set it at about 80 hz.
What happens if you play bass on a guitar amp?
Your speakers will blow out. A guitar amp is not meant to handle the low register of a bass. Even on a practice amp.
Can a 250 watt amp push 1300 watt subs?
In most cases, the speakers should be able to handle more watts than the amp can deliver. Doing it the other way around will blow out the speakers.
When hooking up an amp and speakers do you wire the speakers through the stereo or the amp?
Hook your speakers up to the amp.
Will my 2 speakers both 140W blow with a 450W amplifier?
Yes, most likely. If your speakers are rated for 140w each then it's possible to blow them if your amp drives em at full power. If you do hook them up then find a way to limit the volume or output of your amp. Sophisticated amps and stereos have settings that allow you to do this.
How many watts are factory speakers for a 1997 Crown Victoria?
Most factory speakers are any any where from 10 - 25 watts RMS. I wouldn't put factory speakers on an amp unless you want to blow them.
Will 760 watt 2 channel amp power two 300 watt sub woofers?
Yes, but the amp is too powerful and if turned up to full volume will blow the speakers.
Audio cuts out when you turn up radio?
you are exeeding the factory amp and speaker ratings... its so you dont fry the sterio or blow the speakers
Can you blow out your speakers if you use the wrong power amplifier?
Speakers can be blown if the wrong power amplifier is used and damage can be done by either overpowering or underpowering the amp. For example, if the power rating of the speaker is 300 watts capacity you will need a 300- to 600-watt amp.
What should I know before purchasing a new car amp?
Definitely make sure that the speakers you plan for the amplifier to power are strong enough to handle the amp. That means their wattage should meet or exceed that of the amp. Otherwise, the amp will blow your speakers. Also, it's good practice to use bass blockers on the front speakers. These are very inexpensive, and allow you to hear the high- and mid- frequency signals with more clarity while all the "boom" is in the back.
What if you have 2 subwoofer and for 1 speaker its 1500rms how many watts should my amp be?
the amp has to be less than 3000 or it will blow the speakers at full volume., but it can be more so long as you dont turn it up full
How do you connect your speakers to your aftermarket amp in a jeep charokee amp?
The RCA's from the amp will be arn to the CD player, then you need to connect the speaker's wire to the output + and - of the amp, this will cause the amp to have musical power from your radio, and the speakers to have the power from the amp..-Shocker
Can you power 2 door speakers on a mono amp?
A mono amp will not sound good with door speakers. There are to be used with subwoofers
