How to run 4 speakers off 2 channel amp.

[Arctikz]

Hey guys i know its possible to do but i just dont know how to do it.

I have the alpine type-x component setup and i have a mtx 2 channel amp that puts out 40w rms at 4 ohms per channel and 80 rms 2 ohms per channel. I have inline crossovers that i need to use on them. The speakers have a 60w rms and 180w rms. But im not sure what the ratings are for each speaker.

Do i divide those numbers by 4 since its 4 speakers so they are at 15w rms each?
How would i wire these speakers together to get a good power rating to each speaker?
Do i run the woofer and tweeter in series or parallel for each side?
Does anyone know of a wiring diagram for this kinda thing?

Also if this amp doesnt work, Should i get the alpine headunit power pack or should i get the alpine f300 4/3/2 channel amp and power them. The Alpine amp is 50w rms per channel at 4 ohms. The head unit is 45w rms to 4 channels but it just seems more confusing to me since i dont know how it would work well with the stock amp. The guy at the audio store said i should get the headunit power pack and then wire it to the front speakers and still use the factory amp because it will just power it even more. This seems weird sounding to me.

Do you mean 4 speakers, or a pair of components?

If components, just run the amp to the crossovers. There should be a +/- in, and then +/- out for the woofer and one for the tweet. Your crossover should sort out the wattage. Just don't crank the gain up all the way on the amp.

[Arctikz]

ok so what wires go where? and yes its a pair of components

[JDMrecovery]

I'm hoping this is what you're asking for...

[Arctikz]

heh. theres two positive and two negative inputs on the cross over. And i just hooked it up yesterday and something is def wrong. I think my head units RCA ports are messed up. I beleive this because i have had my alpine type R sub working for 3 months and ever since i plugged my second amp in, the sub wont work right without the 2nd set of RCA cables to the mtx amp being plugged in. And it doesnt matter if its the right or left.

So basically, The mtx amp can be unplugged from everything, (ground, power, remote, speaker wire) but the RCA must be plugged into it for the sub to hit. I mean the sub WILL hit without the RCAs being plugged into the mtx amp, but not hard at all. I can even unplug the RCA;s completely from the back of the headunit and still the sub wont work right. Its basically acting dependant on the mtx amp to work right. And the RCA are run on opposite side of the car. So ive deducted that since Pioneer is famous for being shitty on the RCA side of things, im buying a new alpine head unit to fix the problem hopefully. And i think that the rca's got messed up because i switched the rcas on the back of the headunit with the headunit still on.

But just to make this clear, I have a input for tweeters and input for woofer so i have a (+/-) (+/-) on the input side. Do i hook it up like this? (+/-) (+/-) in a bridged manner of somesorts. Or do i run two speaker wires from each channel leading to each input?

suggest you find a local installer.

Gr i hate people that say that kinda stuff. I mean thanks but if i wanted to go drop a couple 100 dollars on something that might be simple, i will. But i cant just take my car into a tech and say find the problem fix the problem, because they will find 1000 dollars to fuck me over with saying

"we found little unicorns in all your wires so we had to replace all the wiring in your car and also the subwoofer had a gnome chillin in the box so thats why it was messing up, but we threw it out and got you new stuff at the low low price of double what it originally cost you so dont worry, your all taken care of." End exact qoute.

I want insight, not a general comment that i see in every single thread.

If you could post some pics of your crossover it would help. Some of what your saying sounds a bit off.

Post pics of your amps too and it will be easier to help.

Not every store is out to "fuck you". I would say most shops are honest.

I have to agree with attack eagle. From this and your previous threads you really have no understanding of how a sound system should be wired. I highly recommend you read up a bit or bite the bullett and take it in to someone before you damage some equipment, or the car.

I am not trying to be a buzzkill, but just trying to save you some headaches, and $. I suggest you go to a reputable local installer and get a quote. You can always say no.

I trust Street Beats on the west side of Wichita. If you have "people" in the other shops, take it there. If nothing else, just call an Alpine dealer, and ask them about the wiring.

The 4 inputs would be for bi-amping, that would be for running a seperate channel for the tweet and woofer. There should be the option to run them off of one 2ch amp.

[Arctikz]

Well im going to get a new headunit then go from there.
And ill get some pics of the crossover.

well my INSIGHT is that if you can't be bothered to locate and read the installation manual for the speakers, and /or can't understand the simple diagram contained within it that you are simply NOT CAPABLE of installing them yourself.
It is thus cheaper and a better use of everyone's time for you to take it to someone who can connect 3 pairs of wires to a pre-labeled box.

Truth may not be what you WANT to hear, but it is still the TRUTH.

[JDMrecovery]

curious... was there not a jumper included in the component set?

o really? Because i did read the manual and it says nothing more then how to put the adapters on and how one amp goes to the cross over or two amp goes to the cross over. It says nothing about the correct terminals. And i know how to install an audio system just fine, mine just has a problem that is beyond my control (bad headunit). And frankly, your acting rude bro. If the headunit doesnt work i had already planned on taking it to a pro. But if it matter to you, when I DID have a pro look at it, they said they had no idea what was wrong and that probably the headunit is bad and when i fix that i should come back.



here you go guys. Heres exactly how my system is wired. Please let me know whats wrong. And yes theres a remote wire i just didnt feel it nessecary to put in there. And like i said, the sub wont work with out ONE side of the rcas to the mtx being plugged in. Which is the basis on thinking the headunit is fried


Heres the cross over inputs and outputs


Heres the amp

I just installed Alpine X-Series speakers in my car, and the manual had everything laid out very clearly...

Here's their wiring diagram. It couldn't be any simpler. With a stereo amp, one channel goes to the crossover input, jumpers are left in place, one output goes to the woofer, and one output goes to the tweeter, just like the diagram you were given above.

I echo everyone else's sentiments. If you can't sort it out given that information, it's not a good idea to dive in yourself...

[dkindig]

Okay, just saw your pics of the crossovers. It looks like the inputs and outputs are labeled WF and TW.

The outputs are self-explanatory. WF out to the mid-bass, TW out to the tweeter. On my crossovers, for a single input (not biamped), you use the mid-bass input (WF IN) and leave a jumper in place that routes the input signal from the WF IN terminals to the tweeter crossover network.

For a biamped arrangement, you pull the jumper and run one channel from the amp to the WF IN and one channel from the amp to the TW IN.

On my crossovers, the jumper for using a single input is labeled "Signal Link".

Damn well i bought these things on ebay and maybe i didnt see them but i never saw those diagrams. Ive looked hard for a diagram but i guess mine didint come with one which is probably the source of my problem. But ill try that setup. Thank you sir.

well wiring it that way didnt work either. Ill get a new headunit and then see if it works and report back.

[Arctikz]

I bought an x100 alpine headunit and it fixed the problems. Guess i was right huh?!?!?! Wurd. The alpine mrp500 amp was using the mtx amp as a headunit for the remote wires and the rca plugs. I know this because i cut the remote wire at the headunit and the amps stayed on. i then removed the remote wire from the mtx amp and the alpine shut off.

[randomy]

uhm congrats ?

[Arctikz]

troll.

[attack eagle]

you never saw those diagrams because you never bothered to look up the install manual on alpine's website.

you never bothered to connect the remainder of the equipment correctly either (rem wire/ capacitor, etc)

Thus, I was never bothered enough to care...


nevertheless congrats on just happening to solve the problem...



BTW: How did a head unit install magically connect your x-overs ?

[Arctikz]

lol hows the remote wire and capactor not hooked up right. No one said it wasnt according to the diagram i drew up.

And my speakers didnt come with that diagram so how would i know how to hook it up? And ya i couldnt find it online. Sorry.

And someone already explained to me how to hook up the crossovers so they were hooked up already. I just swapped headunits and its all good.

I will say though that the Alpine iDa x100 doesnt push my subs very hard. I have the tremble all the way down on the headunit and the crossovers and the bass all the way up and then adjusted the gain to half and the bass boost to 25%. It sounds almost as loud as the pioneer i had but wayyyy more clean.

Anyway thanks to everyone that helped out.

O and after all this confusing stuff, the components suck. The tweeters get loud but i hear crackeling. And ive been taking them easy to break them in but its getting old to turn it up and then hear a crackle. And one already blew. And im honestly not blasting them. But i get replace a tweeter for $12 so its ok.

[attack eagle]

well your cap is supposed to go across the + and negative at the sub amp... not in series with the positive before the distribution block.

no remote wire is listed.

Alpine has all the manuals on their website...

and you have other issues if you are blowing tweeters and running 18+ db of bass gain and pulling treble all the way back

with all the 12-18 db of bass boost it would be no surprise if your amp or sub were the next to quit, honestly.
you really need to see a knowledgeable individual... local and in person.

[Arctikz]

o well i didnt wire the cap in, a pro did :/. Thats why i dont trust pros. I used to have it on just the positive going to the sub but he said thats wrong.

If you read the post it says i didnt draw in a remote wire because it didnt find it nessecary to draw one in.

I couldnt find the manual. I put in the part number and it said no results.

My bass boost is at 2 db +... And the gain is .5. Im buying a new amp to run the components because im thinking that the amp is the culprit. One of the channels doesnt work so im assuming the whole amp is pretty f-ed up. It was free after all.

What might be the problem if the treble and bass is so unbalanced? I took it to a local shop yesterday and they said they didnt know. They looked at how i wired everything and they said everything is good.
