Hey all, I've currently got a fairly powerful sound system in my car at the moment (Impreza MY99), but am looking at doing some improving!
The current setup is as follows:

Alpine 9855 (dont think any improvement needed here :p )
Inphase 12" Subwoofer (~700w RMS) on Inphase IPA900 2channel amp, bridged and roughly at 350w RMS with bass boost +3db on.
Front speakers are only coaxial inphase 6 1/2" jobbys, although perfectly loud enough, I know i need a good pair of components up here to sound better!
Rear Speakers are Kenwood Dual Mags (very thin) component speakers.
Both sets of speakers are on a Kicker 4 channel amp with ~ 55w RMS going to them each.

I have more than enough bass, but will be looking at adding the 2nd 12" inphase for fun anyways.
But what I am mainly trying to achieve is more volume, and a lot more mid bass. As it really does seem quite hard to get some decent bass from this car with just speakers! Even when amped I struggle to get bass from them at good volumes, it was only when I fit the subwoofer that it started sounding good!

Although I know people like to make a good sound stage for the driver, I am personally not that concerned, as long as it sounds like its majority infront of me, and some fill behind that's great, but I do carry rear passengers often, and of course they like to have the music with full frequencies (ish) so they can hear the music properly too.

Now who wants to lay some recommendations to me!! :eek:

Cheers

Hmm i don't like the idea of running the rears off the headunit that I hear all the time on here. because then there will be two different sound quality levels, and distortion from the headunits amp comes much too easy, but then again, I run it rather loud..
 
I havent got a problem with getting a new amp and set of speakers, but I cannot let the rears just sit back and not play along.
The rear needs to be almost as capable as the front in terms of volume, bass/mid doesnt really matter in the rear, because my passengers backs will be being massaged by the sub :D
 
the first thing I will be doing is getting some good front component anyways. I'd just like to know what people recommend. Also some recommendations on a good powerful 4 channel amp would be great.
I really do like inphase stuff, so am looking at getting their front component set (6 1/2") with their 1204 4 channel amp (100W RMS per channel)
any other suggestions? :)
 
ok guys, really please stop recommending that I dont run the rear speakers off an amp, as I will be doing so no matter what any of you say, as like I said, I like everyone to enjoy the music, and not just me up front!!

Currently I am running the crossovers so that the front gets everything above 160hz (I would like this to be much lower for better bass response up front)
and the rear plays 80hz to 16khz so that the rear has some great sound, but not enough to push the soundstage behind me!

I will NOT be changing the subwoofer and amp on it, as I think it is a great subwoofer. I used to have a Infinity Kappa Perfect 12" and that was PANTS!
After hearing a new Mini with a full JL setup, and then hearing my brothers Inphase Full setup back to back, I believe that Inphase is quite a strong brand. But thats a different matter altogether.

How abouts someone specs me some great powerful front components, with a pretty good four channel amp...?
 
depends what I'm willing to do, theyre currently on the equiv of a parcel shelf in the scoob. I've got 6 1/2"s there at the moment I think!
But ideally I would like to move them down to the doors, and so will be building some sort of door builds when i move them!!
 
so the people in the back will hear everything from the front with a good set of components.... :rolleyes:
you say you've been there and done that... but were you considering the people who sit in the back when you run your ICE.... I doubt it!

Running the fronts at 160Hz will miss out an awful lot of mid-bass frequencies. If the sub is running to 160, you'll get nasty loud booming bass which you don't want.

Personally, I would run the fronts from 80/90Hz upwards, run the sub 90Hz and below and the rears at 100Hz upwards.

That SHOULD solve your loss of mid-bass.

Hey mate, I am planning on dropping the crossover to around 80hz for when I get some good components that can handle low/mid bass with a lot of volume too! but it would seem getting those recommendations is harder than I thought...
 
sorry but in my opening post i said this

"Although I know people like to make a good sound stage for the driver, I am personally not that concerned, as long as it sounds like its majority infront of me, and some fill behind that's great, but I do carry rear passengers often, and of course they like to have the music with full frequencies (ish) so they can hear the music properly too."

Meaning I don't want to hear the whole soundstage thing, I was asking for advise on what component speakers and amp would be a progression for better sound quality and volume, more specifically I stated midbass..

Well all the ice experts on here are wrong then as they are reccomending running them off HU, not running none at all :) Plus I prefer not to have to turn the front up to such a level that it is deafening me so the rear passengers can better hear it.

someone who thinks like me..!
 
That's why I said I didnt want to run my rear speakers on the Headunit.. because the distortion occurs far too easily:

I too would like an explanation as to why it is considered a good thing to do, and please dont say "soundstage" as the gains can be set low on the amp, but thus preventing distortion!

O i see it that way, but I also see it in that, if i was in the back, and i couldnt hear the music all that loud when someone was trying to show off their ICE to me, i wouldnt be all that impressed... ;)
