Rear Fill - Needed???

[dangerous_daveo]

Ok, I have a Cefiro, 10inch JL sub, 5 1/4inch MB Quart Discus splits up the front, both running off amps.

Question being, do I need rear fill at all, I have some cheap VDO 4inch two ways I can put back there, or I can put the 6x9s back (the carrozza jap ones that sit on the parcel shelf). Like is putting anything back there going to distort the sound I already have, or will it just make it sound more 'full' so to speek.

Also, where would the best position for the sub be? (pre fab box)

Personal preference I reckon Dave...

I like a bit of rear fill, keeps the kids happy My setup basically: 12" Sub, 6.5" Splits in the doors. Both powered by the amp, 6.5" Coaxials in the parcel shelf powered by the deck with the fader slightly to the front...

I reckon the 6 x 9's would make a mess of the sound, but ultimately be louder... In your situation, I'd either go with the 4's or fork out for some cheapish 6.5 coax's...

Struttos on the money here - the 6x9's won't be great so the 4's or coaxs would be the go.

Personal preference - I have always liked rear fill but usually it only accounts for about 10-20% of what I hear in the front.

When there's someone in the back I up it a little so they don't just get bass'ed out (don't have sub in cefiro at the moment so no worries there).

At the moment my setup consists of a 4x60wrms (or so) pioneer gmx-414 amp powering 2 focal kvp2 6.5" splits up front.

The stock 6x9's are crap but are currently powered by the 7450 pioneer head unit for tiny amount of rear fill.

When I get off my fat ass I'll be ripping the stockies out and putting in some el-cheapo 6.5" phillips drivers in the back which came from a splits set but won't have the tweeters (one was crushed in the a piller so bugger it) and they will be running from the amp.

Can't afford my amp+sub yet but I'd like it to be a 1.400 audison + ID max 12" of some sort..... heh still don't have 1-1.5k for amp+sub so I think this may be in a year or two

Good luck tho davo - nice avatar btw.

Again, 6x9's would be a poor choice as I find the tweeters to be too bright and will drag your sound stage to the rear.

6.5" coax's would be ideal and I usually fade the head unit around 75% to the amplified front, 25% rear.

When you put it that way I dont think I'll bother with the stuffing about.

Any thoughts on the sub positioning tho?

I have Rockford in front and in trunk. But I have also rear fill with Rockford coaxial, not just because there is space for it, but it is needed with the upcoming surround processor!

You sit at the front and your ears face forwards. The only time you need to upgrade the rears is if the people in the back aren't happy or you're running surround sound.

I don't understand the use of an American full range speaker when many of the local products are very good in Europe.

As for sub positioning, I would just put it where it is most practical for daily use of the car. As for firing direction, trial and error would be the best bet but not many can be bothered knocking up a dummy box for testing, unless of course you dont plan to mould the box shape into your install, then you could use the dummy box full time

[dangerous_daveo]

The sub is just in a pre fab box atm. No plans in the near future of doing a proper install.

yeah.... rear fill I think is essential actually for a good sounding setup. Some say its optional, but I disagree.

At the moment, in the R31 I just have a pair of 6" fronts, and a decent amp powered sub, but the whole setup still really lacks the "fullness" that I like where the sound is coming from all around you. It was much better in the R33, with the 4x speakers and the sub.

Don't use the 6x9's like people are saying, but some 6" (even cheaper ones) should do the job nicely.

Yop, and more is to come in that Skyline, I can promise you.

Btw, rear fill was included in the first step, no discussion when we did that. If there is a space for speakers, fill it!
