i have a jeep and right now i have some pos sony speakers up front and stock in the back, well i bought some new alpine speakers for the front and was wondering if i should put the sonys in the back or not, i will have 2 15inch subs in the back so im pretty sure that would drown out the back speakers but i might not have my subs on all the time, so should i put the sonys back there or just take out all the rearfill completly.

there r ppl here who would make u believe that rearfill is absolutely NOT necessary - but it depends on ur listening tastes personally .

I like a certain amt of rearfill sounds in my setups & if u have it u can either fade in more of less power 2 it depending on the type of music ur listening to or the mood ur in like i often do ...

I would keep the sony's there and allow them to be powered by the hu, no need to buy nice rearfills if the subs will drowned them out any way

well tell ya what.. I'll give ya both sides.
I have an article explaining the downsides to rear fill, however I had rear fill in my grand cherokee, and I'll give ya a link or two to that as well.
decide for yourself. generally I recommend rearfill for two things. 5.1 AV systems where you require rear channels, and large vehicles with passengers who often sit in back.

for SQ vehicles where the driver is prime listener, scrap rear speakers.

nice article, my only question is that the sony speakers are coaxial, and it says in the article not to use coaxial speakers as rearfill, so should i use them anyway or no.

I have a pair of 3way coaxial 9x9s in the rear of Neon, but 90% of the time I have the FIE on my pioneer deck turn on cutting out the rear highs at 250hz. But when I have rear passengers or when I'm smoking a cigarette with my front windows down on the freeway I turn off the FIE and the tweeters in the rear prove to be essential.

coaxials work as rear speakers for 5.1/DD systemd (DVD) and with people in the back seats who want full range and not just bass from the subs drowning out everything..
again if this is just for the driver, I'd go with straight midranges in the back doors on narrow band notch filters.

I ride with friends so, I think the 6x9s is needed. =D They are my rearfill 4ways, and they can still out do the frontstage at the momment. =D


Glasswolf I must ask, what kind of Alarm System is in the Cherokee??? It looks killer, sought of how I want to wire my new 2way alarm with a "trunk pin" like the hood pin.

it all comes down to how you do it and how much control you have over things like gain or overall volume to the rears. Rearfill is exactly how it sounds, never a rear stage where it competes with front stage. I've heard the Focal Altima that has a comprehensive rearfill in a stereo setup and it was a killer SQ vehicle. Thing is most people on here aren't going to be SQ competitors and they probably won't notice a difference in done correctly. While even I know i have a more discerning ear than most, I have rearfill and my car is truly SQ and not even a 5.1 setup. The biggest thing I notice in having rear fill is that when driving with the windows down doesn't effect the level of my sound as much as when i only have a frontstage. Just get a good fronstage and then a minimal rearfill and you'll be good.

well im pretty sure thats what im gonna do but my only worry is having coaxs back there is that its gonna sound like sh1t, cause your gonna have the lows of the subs and there gonna drown out the midrange, but your still gonna hear the tweeters and upper range, which i think will make it sound like azz.

ok I strongly recommend if ya do use rearfill, stick with 2 ways.. 3 and 4 ways will be way too bright and it'll trash your soundstage in front.
2 ways also tend to give better lower midrange/midbass response.

B; I used a (fairly cheap) Clarion Ungo 2004 on the jeep with some othere sensors/features I added to it (like the screamer and hood bolt)
the charger, I used a top of the line Compustar.

yes coaxials.. as opposed to the triaxials or 4 ways and 5 ways some companies make.
all the 3 ways or more do is add more tweeters and supertweeters to that center pole cluster, making the treble brighter and harsher.. which draws vocal ranges toward the back of the car.. whereas ideally you want everything to come from in front of you liek you're at a live show.

glasswolf....how would this sound. get a 3 way component system and put the mid bass driver in the rear deck and the mid and tweeters in the front door. will the subwoofers in the trunk cancel out the mid bass drivers in the rear deck?

won't work.
3-way systems need to be together, or aligned and equi-distant from the listener (path length) or they'll sound lousy.

3-ay systems rely on the midbass driver for the midrange as well, and use the midrange driver (usully 3") for upper midrange only..

hey where ya been man? good to see ya back. and just when I was getting all put out due to a bunch of drama on another forum. Always good to see a friendly face again after an absence.

yeah its a cahrger, and actually you came back the week I'm starting a teardown of it for a winter rebuild. I'll be posting pictures of the project, so stay tuned. I'll stick a link or two for them as they're posted up here. I picked up a new digital camera for xmas so I can take some pretty sharp images now, up to 9MP.

I may go with this set for my rearfill which should compliment my CDT HD62 component set also. Nice coaxial for anyone interested.
