can you hook door speakers to an amp?

Question 1
can you hook door speakers to an amp?...  can i hook my 6x9s and door speakers to a 2 channel amp with out it over heating? or do i need a 4 channel amp

Answers
1)   you need a 4 channel amp - Juan

2)   I can't feel my legs - Mc Fly

3)   It all depends on the power handling of your speakers,

If your speakers can handle the wattage output of your amp, then you can hook them up without any problems.



You haven't given enough info for us to give a good answer,

such as the model numbers of the speakers and amp.

or at least the RMS and OHM rating of the speakers and RMS @ 4 Ohm rating of the amp. - Aaron

4)   You CAN hook up four speakers to a 2 channel amp.



As long as the amp is "2 ohm stereo" stable, which virtually every single 2 channel amp is. And as long as each speaker is 4 ohms, which most car speakers are.



You will lose fade capabilities, though. Or balance, depending on how you wire the amp. - odinsragess

5)   Well i would suggest getting an 4 channel amplifier, but a 2 channel will be find aslong they are not over powered. - Matt

6)   if they are factory speakers, the wont be able to handle too much. you can run 4 speakers off a 2CH amp, most amps will have no problem with this, however I would also upgrade your stock speakers first, it will sound better even without the amp. - clawless

7)   Usually you can, as long as each channel is stable down to 2ohms.



Almost all stereo amps are stable at 2. - Brad J

Question 2
is 50W (RMS) Total Power Output good for an external speaker?...  so is it good? what is better? is it loud and clear?



Please help me :)

Answers
1)   50 RMS has absolutely nothing to do with quality of sound, loudness, or anything else.



It's just a measure of electrical power.



Think of it this way. Is 100 horsepower good?



In a Go-cart, it's plenty. In a ship, it's nothing. In a car, with poor gearing, sucks. On a skateboard, it's stupid fast.



All depends on how it's used. Number really doesn't matter as much as those bragging about it would like to think.

It's pretty much entirely useless. - Vipassana

2)   not really if your trying to be a douche bag and play your music loud you'll need a lot more - Robbie

3)   that's just what the sub can handle continuously that's it. just go somewhere you can hear car audio and pick out the ones that sound good to you. - NE-truck

4)   I would get something around 200W for a coaxial speaker, more watt will make it more loud and if you want it to be clear make sure its a 2 ohm speaker. Good luck. - The Person 99

5)   Don't worry about the wattage to much, though that seems a little low. Instead look for other things, the craftsmanship of the speaker, the materials, the shape, is it 2-way or 3. These things make more of a difference than than the (RMS). I think that number is really only useful when your considering whether you need an amp or not. And with 50W that is a definite no.



I have a pair of 150W 3-way Rockford Fosgates that sound much better than a more expensive pair of 200W 2-way Infinity's. - Shawnywan

6)   Depends on the size and quality of the speaker. Also depends what you are using the speaker for. If you are using a microphone to make a speech or commentary, then it is more than enough power to do the job. But if you are using it for music for maybe a party or something along the lines, maybe you might need more power. But even that could be enough if you know what you are doing. If it is a car stereo using a car speaker in an external box that you can detach from the car, then yes it is should be good enough using it for mids and trebs. Not good for a sub, however, you will need more power to have nice, hard bass. Make sure that the Ohms of the bass matches the Ohms of the amplifier being used. You also need to know that RMS is the total amount of continued current that is being pushed to the speaker. Has nothing to do with the total amount of watts that the amp uses and has. Whether the amp says 100 total watts or 1000 total watts, that is only the amp and not RMS. RMS is the total amount of current supplied to the speaker in a continous form, while Total Watts are the total watts that the amp has. - Blood_Robot

Question 3
question about my car amp?...  i have a 200 watt amp i went and bought the kit for the amp and i just purchased a 1400 watt amp can i keep the same kit for the 200 watt amp and use it for the 1400 or will i have to buy a kit for the 1400 watt?

Answers
1)   probably not unless you have a 4 gauge kit. With the added power you are going to be drawing more amperes which need a larger wire, or it will heat up the wire and melt it. With 1400 watts you might want a 2 gauge kit or even a 0 gauge wiring kit - That Guy

2)   Probably not. You should get a 0 gauge wiring kit, so in the future if you choose to upgrade your other components, you won't have to upgrade your wiring kit! - Erik

3)   Probably not, do you have the model numbers of both the amps or a better description of the wire too? The main problem with the wiring is the resistance and voltage drop when a high current is used you also have to check if your 1400 watt amp is peak i'm assuming unless you paid like 1k for it in which case i don't know why you'd care about another hundred to drop on a wiring kit. see how it sounds first if you need to upgrade it upgrade it. odd's are if it is a problem the fuse will blow and that's how you'll know to go bigger - steve

4)   Only if you have short power lines, the longer you need to run a power line, the bigger the gauge you need.



Yeah, you'd probably need at least a 4 gauge at minimum, depending on how many amperes your amp is drawing, 2 gauge would do the job, 0-gauge to be safe. - Aaron

5)   I would say keep your wires if its a 4 guage wire kit. If theyre smaller wires, then yes i would upgrade to atleast 4 guage. 0 guage sets are over doing it, they are super thick and you wont be drawing that much current from a 1400W amp. - WigSplitta

Question 4
What are the best type of 12' subwoofers.?...  I have a pontiac GT G8 and want some boom in the trunk..



:)

Answers
1)   Try anything from Memphis, Alpine, MTX, JL audio,

I have the Memphis M3 series the 10" handles 500 RMS sounds great - joel

2)   Incriminator Audio makes some great product for a cheap price



http://www.soundsolutionsaudio.com/store/products/12%22-187-Series.html



They get so loud it hurts my ear, and im used to a lot of bass - That Guy

3)   Alpine Type-X's are great. I have two 12" Type-R's (a model lower than the Type-X) and they are great. The Type-X has twice the power handling of the Type-R's. They handle 1,000w rms each. That's quite powerful for a 12" sub. - Erik

4)   Elle, the "best" is subjective, and everyone has opinions on what is the best. There are 15+ brands that are good quality and have products to fit almost anyones needs.



All the answers above me are good. The amp and box is JUST as important as the sub itself too! - odinsragess

5)   ok bla bla bla lol now thats over eveyone has a different idea of what sounds good !! the best thing to do is go to the store and see what sounds good to you.

there is SQL (sound quality level)

and SPL (sound pressure level)

one sounds good and one sounds loud

so if you want a lot of bang for a little buck then go for SPL but if you want sound quality get SPL

you can have best of both worlds and get a high end SQL sub that can hold some power. but it does get expensive. in all honestly a good in between SQL and SPL is MTX they have a good sound and you can pound on them out of the box. - NE-truck

Question 5
i dont know wat can cause this problem?...  i got two 12" 250 wats a piece i had a 600 wat amp powering them for some reason i turn my car on in the morning tryed to put my music on nothing the green light was on the amp i changed the fuses on the amp nothing i know for a fact everything was hooked on properly i took the amp of took it to my buddy he gave me a bran new one i hooked it back up it worked perfectly until the next day i had the volume turn up fairly high then the subs cut out i knew it was the amp i took it off brought it back he gave me another one i hooked the third one up now every time i crank it the amp gose into protection mode but only when i crank it im really curiouse wat could cause this issue

Answers
1)   Try hooking the subs up in someone elses car. The problem might not be the amp. You could have a bad coil. - Joe

2)   subs wired incorrectly for this amp, the amp isn't stable at the ohm level your showing it. - clawless

3)   buy a toyota camry to fix the problem - James

4)   Take it to somebody that knows how to match the impedance of the subs with the amp. It sounds like your load impedance (subs) is too low for your amp to handle. Check the impedance stability rating of the amp then see if your subs are in fact wired to a lower impedance. I could tell you how to do it but you didnt mention anything about the subs other than 250W a piece. Not enough info. But send me an email if you need more help - WigSplitta
