can i run 4 alpine type-x speakers throgh a multi-channel amp and share a 10" alpine sub with that same amp or would it be safer to just run two amps...one for the speakers and a 2 ch.mono amp for the subwoofer....thanks

 

run two separate amps.if you run a full pass signal through the sub it will mess up the voice coils.

No it won't. It will just sound like ****. And to answer the original question, run 2 amps.

 

2 separate amps, unless you have a 5 or 6 channel amp.

 

thankyou very much

 

IT WILL ALSO OVER LOAD THE VOICE COIL WITH TO MANY SIGNALS IN THE RANGES IT WAS NOT INTENDED TO PLAY.IN TURN IT WILL OVER HEAT THE COILS AND BURN THEM OUT.I HAVE SEEN IT HAPPEN.

 

heat kills voice coils, not frequencies.

Too many signals? My sub is only getting one signal. It is composed of multiple frequencies, but it's only one signal. And the voice coil is an inductor. And inductors filter out high frequencies. You don't seem to know about this stuff, so I guess it's pointless to argue about it.

If you're so sure about it, why don't you take any sub, hook it up to a full range signal, and then look at its output with a spectrum analyzer. How much high frequency content will you see (by high frequency I mean above 10 kHz)?? None. That's because the inductance of the voice coil will filter that out.

You have probably seen people turn up the gain too much, and the clipping amp took out the voice coil. Full range signal or not makes no difference.

Afterthought: how do you overload a voice coil with too many signals?

If it is a 4ch amp, 2 channels can be used for high-pass and the other 2 can be bridged into mono to run the sub, [again depending on amp].
However I agree with the others, the best way would be 2 amps, one 4ch amp to run the high-pass, [the 4 type-x speakers] and a mono block, [1ch amp] sub amp for the sub. 94

BTW "a 2 ch.mono amp" is an oxymoron, is it not?

One more thing, there are no stupid questions, just STUPID ANWERES

 

there are a few mono block amps on the market today that can run sub frequencies and speaker frequencies simultaneously:
mtx's adaptive series
orion 600d
expect to pay a pretty penny for these the mtx series start at 289.95 for a 250 watt amp

just go with fcm's advice and get a good mono block amp AND a dedicated speaker amp

Nope. A 2 channel mono amp is an amp with 2 channels, both of which get the same signal. A 2 channel monoblock is 2 separate amps in one chassis (power supply and amp for each channel).

So you're saying that taking 2 amps, putting them in one chassis, and sending them the same signal can't be done? To me, that would be a 2 channel mono amp.

I guess that it depends on how you look at it. If you're looking at line-level signals, sending the same signal on both left and right is mono. Then you would have 2 mono channels. But when looking at amps, mono would mean only one channel.

yea i wanna know this stuff too so yur saying that a 2 mono the signal is equal to both channels not like a 2 channel(stereo)amp?

That's what it seems like to me. The amp might have left/right inputs, but they are summed to a mono signal. Then that mono signal is fed to both channels of the amp. That's why it would be called a 2-channel mono amp. A regular 2 channel amp (stereo) will also have left/right inputs, but each one of those goes to a separate channel.

 

OK this is getting out of hand, if you had 2 mono-block amps in one case and an input for each amp and plugged in the left signal into one and the right signal into the other one and connect the left side speaker (s) to the output of the mono-block with the left input and the right speaker (s) to the mono-block with the right input, you would have stereo, but you would still have 2 mono-block amps, not a 2ch mono-block amp, the same goes if the input signal is mixed, ["summed"] before it goes into the amps, you still have 2 mono-block amps, not a 2ch mono-block amp, [maybe dual or twin mono-block] mono means one....

mono prefix 1 one, alone, single [monocracy right out of the Webster

In the 30+ years I have been installing car audio, this is the first time I have heard the term 2ch mono amp. nuff said.94

Then it can be either. What would be the difference? It's the same thing, so call it what you want.

2 mono-block amps means 2 separate amplifiers.

As I said before, it depends on what you look at; the signal or the amp.

So people are supposed to use the same words/phrases over and over and not come up with new ones? That would get boring after a while.

 

Boy I sure needed a good laugh today. a few thoughts:
- There are such animals as dual mono amps ...research the amp company
Genesis-the are very popular with the SQ crowd .
- Hit RF's(Rockford Fosgate) website and click support. Search Rockford System design. You will come across a set of system designs on how it used to be done...
before mono blocks and digital surround processors. The designs were taught by RTTI ( Rockford Technical Training Institute) back in the day!! FCM was right,passives xovers will be needed...but how cool was it to do the ultimate system and have it run off a 15 watt X 2 amp!!!! Man those were the days.

Have fun. 25yrs and counting

All the memphis mclass amps, the 250d ,500d,100d and so on are the same.they are mono block amps but have two channels.

i OWNED TWO MEMPHIS 500D'S AND ONE 1000D.They have two sets of speaker outputs and one set of rca inputs just like a standard two amp.

 

That's so you can hook up a standard stereo signal (which will get mixed to mono). 2 sets of speaker outputs are there so you can hook up 2 subs in parallel.
