Howdy,
Just wanted to let everyone know. I have finally managed to get a second pair of splits in my VS commodore!
Now I have 2x Alpine Type R Splits (older version) in the front trims. I kinda expected more volume, but hey ... mite have a look at the amp. The fronts seem louder than the previous rears.
Ill post a pic once I get one.

Dont diss my craftmanship skills! Im no professional installer!
Second tweeter is up near window visor.
Other speaker is in original door trim.

oh my
i think a good set of splits would have bene the better way to go
adding a second set doesnt mean it makes it louder

PM me or email philthy@shoppingsecure.com.au for all your stereo needs
you obviously had a bit of money to spend if you got 2 sets of Type R's, i reckon you could have done much better, and without butchering your door trims like that...when you say it wasnt as loud as your expected, what kind of amp are you using, and how much power are you giving them. I'm not sure about the old model Type R's, but i know the new one's can handle in excess of 150rms each, despite manafuctuers claims...
Unfortunately, people get these ideas in their heads from demo and show cars and think it will be great. More speakers does not mean better... I don't know how many times it needs to be said![]()
Meh ... I had no money to use ... thats why I didn't buy better speakers ... the older type R's are rated for 70 or 75wrms. If I had money I'd gon wit some diff speakers (but I seem to be broke beyond doubt atm). I had an old pair of type R's laying around so thought I'd use them. All I got is 3 little holes now.. big whoop lol.
Edit: About powering them, I had my old Alpine V12 75x4 channel amp to power them. So the amp was half being wasted + the speakers were gathering dust :P
Edit 2: It actually sounds louder now after I adjusted the gain on the amp. The amp had the rear channels at a higher gain than the fronts (obvious reason), so I adjusted them to match the fronts.
Edit 3: It actually doesn't sound bad..... I actually wished I had money to buy newer speakers ..... mine are going on 2 years now![]()

75W RMS speakers running at full tilt will make your ears bleed
Why not run the 2nd set in the rear, bound to be better than having 2 sets in the front??

............ well I thought it was obviousnow not too sure since you question it.
If you had the back speakers the same gain as the front speakers ... you wouldn't be able to hear the back speakers over the front because 1. you are closer to the front speakers and 2. a human ear hears the 180 degrees ahead a lot better than the 180 behind, you do most of your hearing in the front direction.......... so I hear anyway.

If you may not have noticed, the second set of splits were previously my rear set, I removed them because I found that I couldn't even hear them over the fronts. Thought they were just wasting away back there.
The rear speakers are pretty much only meant for passengers in the back .... as I don't carry passengers I don't need them.
As mentioned earlier... If I had money I would buy a hell good set of splits for the front... but I don't so I just used what I had. Unfortunately I didn't pay notice to the rear speakers and just brought rear speakers because it's the norm to have front and rear speakers.... just followed the crowd ... mistake.
When I upgrade I ain't going to get rear speakers again, I'll spend twice as much for the fronts and not have rears.

I don't get it... How can 1 speaker produce the same volume as 2 speakers? How can 75x2=150 equal same volume as 75x1=75?? Wouldn't you get more volume from multiple speakers instead of just one?
Maybe I'm totally off ball, could someone explain please.
Why do people get 2 subs instead of just 1? they stupid or something? because the one sub will get as much volume as 2?

A properly set up car audio system will have most of the sound coming from the front. Obviously people have different preferences, but more sound from the front and just the rear speakers filling in a little bit is how a decent installer would set it up.
2 sets should be louder... But a lot of things can affect it, like cancellation, reflection of the sound and things.
Example for multiple speakers (example dB figures):
1 speaker with 10W = 100dB
1 speaker with 20W = 103dB
2 speakers sharing 10W = 103dB
2 speakers with 10W each = 106dB
Doubling speakers but using the same power adds 3dB.
Doubling power but using same speakers adds 3dB.
Doubling speakers and power adds 6dB.
Hi StoneX, I am aware of double power = 3db gain ratio etc.
So I'm not sure why you pointed this out... I spent ZERO $$ to gain 3db. To my ears I don't it being worse in cancellation respect. I do find it to be louder, and since adding the second tweeter I can hear the highs a lot clearer and louder (could be the positioning, instead of the stock tweeter spot and near the window visor, but the +3db gain contributes).

"Double power = 3db gain"......this means if you double the power going to the original set you'll gain 3db and wont have other issues like cancellation.
Im like a dog with a bone, i know...![]()

If you want a nice clean crisp sound, I don't think doubling the amount of speakers in one location is the way to do it, as you're just confusing the sound.
Umm, you don't adjust the gain on your amp for that, you use the "Fader" function on your head unit to adjust what you can hear from the rear and front.
I only bought one sub for my old car. One very good sub as opposed to the 2 good Pioneer ones a mate had in his VN. Mine shat all over his. I had a JLW3V3 12" in a massive 90mm ported box i made myself, he had 2 Pioneer subs in a box he made. Mine shat all over his in terms of clarity and depth of the bass. More isn't always better.
In other words, quality instead of quantity.

I'd never have 2 subs in my car. I'm buying a single Orion HCCA 15.2 sub soon to replace my single Hifonic OLM2412.
Maybe I am a bit of a douche, but I had thought gain would adjust the amount of volts going to the speaker equaling more rms.
Could you explain the gain for me then? I am willing to learn.. and if you could, could you tell me why the gain was lower 0.8 in the fronts and 1.3 in the backs (exacly same speakers).
Edit: I forgot to mention... I got my stereo tuned at Alberts and they said they don't tune it on the head unit, they tune it on the amps. I thought this was weird .. but they are the car audio people.... one good point to that is, my battery died on me once and once the battery disconnected for a second .. resetting my headunit ... so in that way its good.

when setting up levels between front and rear most people set the fronts higher than rears.
rears should be just for a little bit of fill in the rear.
You really want your sound stage in front of the listening position.
Easy explination to why is how many times have you been to a concert and stood with your back to the speakers???
you dont correct?
The sound when at a concert or watching tv etc is always in front of you. So why when driving would you have the sound behind you???
