Help with system

[Senatex 10+ year member]

First off, I kind of have a small grasp on what I am doing.. Enough that I know what I need to ask questions. Anyhow, I have a few questions..

A brief run down of what I am using.

I am going to be running a PPI A600.2 Art Series amplifier, as well as another Art seriest amplifer with 300 watts rms... So ill be running 900 watts rms all together..

Anyhow im going to be running the PPI A600.2 Into two subwoofers. The Alpine TYPE S, Dual voice coil 4 ohm speakers to be exact.. Mainly because I kind of like alpine, as well as the rms maximum matches my amp exactly.. Leading to my first question..

I want to make sure I understand correctly my wiring for the first two subs off of this amp. First off, from what I was told, is I should be running the speakers in a series off the amp, as so I am able to get 600 watts rms from the amp to both speakers.. Shown here..Is it option 1, or option 2?? I believe option 2 if I understand correctly, the amp wont be able to handle the 1 ohm load.. Im not to sure on this... Anyhow, if its dual voice coil, it says each coil handles 150 watts rms.. So I use Option #2, the speaker is only going to be getting 150 watts rms from my amp right? I dont know, im confused..

Also im going to be running one more speaker off the 300 watts rms amplifier.. Since both amps are the same, besides the rms they are putting off, thats why I choose another art seriest amplifier. So that would be three 12" subs all together.

Anyhow, if anyone has any opinions, suggestions whatever.. Feel free to tell me what you think, no matter what shape or form it is in.. As I am kind of new to this.. Thank you

Of those two options you would use option #2 and then bridge the amplifier to a single mono channel.

That particular amp will create 600 watts+ when in bridged configuration. This will feed 300w+ to each subwoofer.

You can also wire each subwoofer independently to a 2 Ohm load like so:

and connect each subwoofer to its own amplifier channel as that amp makes 300 watts+ per channel in stereo mode.

Either option will show the subs approximately the same level of power.

Higher impedence loads generally equal cooler running overall for the amp in question so the first option outlined above with the two subs wired together for a 4 Ohm load and the amp in bridged mono mode will likely be your best bet here. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Is the 3rd sub to be run off of the other amplifier an Alpine Type S as well?

Yes it is, im going to be running it off of the 300 watt rms art seriest amp. I figured it would be best to keep the same speakers running off the same type of amps for the most part..

I looked at the wiring diagrams for individual speakers.. it looks like if i bridge it, it will be on an 8 ohm load?

Anyhow I understand that wiring diagram for the series for a cooler running amp.. The thing I dont understand is, if it is 150 watts per coil.. and I only use 1 coil, as the diagram suggests.. Wont it only be getting 150 watts?... As for running it off each channel to each individual speaker.. Thats how I have it setup to my current speakers... But they are not dual voice coil.. How does that work with dual voice coil speakers.. Would I be better off getting single voice coil speakers in this situation, or no? Im kind of confused, and for some reason no amount of reading I have done as clarified my situation.. I seem to be missing something I guess, my apologys.. Anyways I do appreciate all the help! Thanks

Okay

If you were to wire a single Dual 4 Ohm voice coil driver with the coils in series then, yes, you would end up with an 8 Ohm load.

However, if you wire those same coils in parallel alignment instead each sub will yield a nominal 2 Ohm load.

Anyhow I understand that wiring diagram for the series for a cooler running amp.. The thing I dont understand is, if it is 150 watts per coil.. and I only use 1 coil, as the diagram suggests.. Wont it only be getting 150 watts?... As for running it off each channel to each individual speaker..

I think you're misunderstanding the diagram. Nowhere in either the diagrams you linked to or the one I posted suggests only hooking up one coil. And no, I wouldn't suggest doing so.

Thats how I have it setup to my current speakers... But they are not dual voice coil.. How does that work with dual voice coil speakers.. Would I be better off getting single voice coil speakers in this situation, or no? Im kind of confused, and for some reason no amount of reading I have done as clarified my situation..

A single voice coil driver is whatever nominal impedence it is designed to be. It cannot be changed on its own.

A dual voice coil driver, however, can be wired to two different nominal resistance loads dependent on which configuration they are wired in (parallel or series)

Ok now I understand single and dual voice coil differences ALOT better.. That simplifies it a bit, for me to understand.. Now

What i was refering to as to only hooking up one voice coil to the series of the first amplifier for both subs is.. in Option # 2 it looks like two of the voice coils on each subwoofer are just hooked together..

But from re-looking at it, it is pretty much just using one coil from each of the voice coil sets.. Correct? in other words utilizing both sets... getting 150 watts rms to each side.. right?

Thanks to your help, I think im beggining to understand this a bit better..

Also do you have any opinions on those particular speakers... Or any speakers that MIGHT work better with my type of amplifiers?

Also, how loud bass wise, do you think 900 watts rms to three speakers would be actually.. As I never have ran more then my two 12 system.. Im just looking for opinions and suggestions, get a feel for what other options I might have.. Anyways thank you for all your help!

Loudness is going to depend on whether you go ported or sealed, and also it's going to depend on the install and how well you do.

The Type S's are decent speakers, I've gotten a single Type S very very loud in my single cab F-150 I used, considering I paid 50 for it used.

One thing I will say is that it MIGHT be easier to use one amplifier instead of two, you could pick up a nice monoblock amplifier that will do the job just fine.

Also - in connecting the speakers in a series, I don't think that you get it, although I might be misunderstanding what you're saying. In order to get a Dual Voice Coil 4ohm woofer to draw a 2ohm load, you connect the two positives on the subwoofer together and the two negatives together, then link the positive to the positive on one of the amps channels and the negatives to the negative of the same channel, if that makes sense -- - -- so it'll be one speaker per channel at 2ohms per channel

As far as how loud - I dont think you have a bad idea, the S's are good little budget subs, but personally I think you'd be much happier with two Type R 12's in a nice ported enclosure on a nice monoblock amp, you can still come out fairly cheap overall with it.

Well the main thing is, I already have the 600 watts rms amp.. and the 300 watt rms amp, i am paying 100$ for.. and probably 300$ total for the three 12" type s, subs. but i do understand what you mean..

Im just wondering what will come out more expensive for the time being you know what I mean? Im not on a low budget by any means.. But considering that I will only have to pay 100$ another amp 300$ for three 12" speakers, the small amount of work to run two amps, is not that much of a problem to me.. I dont know though

 

[Senatex 10+ year member]

If i did go with the type r's.. What monoblock amp would you suggest?

 

[MisterGrubbs 5,000+ posts]

This is probably more complicated than you want, but have you considered using the 2 channel amp for a component set, and then buying a monoblock?

As for as a monoblock to push the subs, there's a million and one you could use

Just depends on what you like and hte pure quality you're looking for

 

[Senatex 10+ year member]

I understand theres probably a million and one i could use.. Just as for price range, as compared to what i was considering doing.. 400$ for two 12"s and another amp.. And quality... What would sound best with two 12" type r's for the price that is..

From what I can see I can get two type r's at a relatively cheap price.. its the amp that poses the most problem..

also I have actually considering running a small two channel amplifier to a component set.. Just getting my subs done first.

 

[Senatex 10+ year member]

I really have as much money as I want to spend.. BUT I am trying to stay as low budget with still having quality as possible.. Not going all cheap, and getting complete garbage.. In other words

 

[MisterGrubbs 5,000+ posts]

Wait - you have two of the 600.2's, correct? Same amps

 

[Senatex 10+ year member]

No, sorry for the misunderstanding.. I HAVE an A600.2 Amp right now, I was going to purchase a 300.2 amp.. Same ppi series, the art series. To run to one seperate sub.. So one amp running to two subs.. The other running to one sub..

What im looking at (possibly) now, is how much it would cost me to just get two type r's.. and a mono block amp.. But for price, yet still having quality.. I dont know where i should be looking for monoblock amp wise..

Because currently I can get, three type-s speakers for roughly around 250$.. then buy a 300.2 art series amp for roughly 100$ or so.. Then though I would have to buy another amp kit, to support the two amps.. which cost a bit extra.. Probably end up costing over 400$..

OR I could get two type r's which cost roughly around 200$ for two.. But its the amp for them that would be in question

 

[MisterGrubbs 5,000+ posts]

Try this then

Those amps are rated 300x2 at 2ohms???

 

[MisterGrubbs 5,000+ posts]

Yeah I checked that far anyways lol, if those amps have a low pass filter on them, buy two type r's and another one of the 600.2's, and run a type r off each amplifier

I wouldnt necessarily suggest it if they dont have a low pass filter, however
