Rear Speakers

[dj petey]

i wouldn't waste time upgrading the rear fill speakers. I've put 75w rms crossed over at 110Hz without any distortion at high volumes so the drivers seem pretty durable. as for fidelity you don't want to rob your front stage imaging with too much brightness in the rear. the real problem is the 3.5" in-dash components are crossed over too high causing excessive brightness. this may be creating too much of a gap between the front and the rear. instead of increasing the brightness in the rear, try adding warmth to the front stage by removing the cap on the driver and crossing it over at around 110Hz instead. This seemed to work well for me. i'm using a 6 channel amp to handle all the crossover work. this also relieved the muddiness of the in-door subs. the oem amp and crossover for the door subs is basically garbage.

what kind of modifications? getting good sound?

Stock Bracket trimming
Getting better sound than stock, clearer

SO- I just got an FRS after my TC was totaled by a drunk driver
I Have seen a lot of posts about "why bother with the rear speaker- no one is back there"

I totally disagree. Maybe I'm picky- but having no sound from the back at all is a very poor option. I enjoy the roundness of sound of a system that you can dial in to get full sound- not just a huge bump from the trunk and sound in the front.

I am searching for an option aside from the 3.5 stock as well and wonder if anyone has found a solution.

I installed some 3.5 infinitys. it took rather a lot of modification to the mount to make it fit.
Edit: when I said 3.5 I meant 4". The screws line up but the speakers basket wouldn't sit in the bracket without cutting

[Envirotech]

I agree. Did a bit of testing today. Rears are not very good. I could not live with just the front soundstage. Much prefer to have music from rear speakers as a fill. Sounds much more full with all working together

[Njjawn]

I was thinking of throwing a set of re audio xxx 6.5" component speakers in a custom bracket back there for some mid bass... Or is that not recommended/a waste of time? I already have the speakers from another project.

Adding a sub and the amps to run a complete sound system overhaul would add unwanted weight to the car (I'm sure this was a consideration when Subaru designed the system). Plus, I don't hate the nav unit like many do...I think the nav & audio system are well integrated.

With that said, I just can't get over the lack of fidelity of the rear speakers. They are listed as 4" speakers; not a great sized speaker. I don't mind making the mounting/cut-out holes a little larger to accommodate larger speakers that would provide greater choice.

Has anyone replaced just the rears? What were the results?

What did you wind up doing?

I went with "2-way" components with tweeters in the dash and 6.5" in the doors. I have my crossovers under the seat but still looking for a better location. All components that I'm aware of are '2-way" setups, but I've seen '3-way' 6x9s that don't fit this car without some mods. The 4" slots in the dash currently sit without speakers in my setup.

There are 3-way component systems made by JL, Hertz, etc. that are like the stock system with 6.5" midbass, 3.5" or 4" midrange, and 1" tweeter.

You could power either setup a few ways. One amp channel per side and using a passive crossover is the most common/obvious.
Can also do 2 amp channels per side. On a 2-way you'd power the midbass and tweeters with different channels and use the amp crossover, no passive crossover. In a 3-way you could power the midbass off one channel then the midrange & tweeter together off the second. Use the passive crossover for this channel and the amp crossover for the midbass channel.
Could do 3 amp channels per side with a 3-way setup. This would be a full active system with all crossover points set by the amp (and HU for the sub/midbass crossover point) and no passive crossovers. Not sure I've seen anyone do this, but definitely possible.

So I have been wondering something.
coaxial speakers are 'full range' but do not need to be used full range, correct? you could build a 3 way passive component build using something like a crx-303 and a set of 6.5 3.5 and tweeter for the front right? I have looked and I can't find much info at all on that particular crossover, but if you google 3way passive crossover there are tons of venders selling them. I expect using something like that with generic coaxial speakers would be a compromise as opposed to buying a tuned 3 way solution, but would be better than trying to use passive inline crossovers, like what come with tweeters right?

I believe you could do that. But considering the cost of 3 separate sets of speakers plus the crossover versus a 3-way component setup, which includes the crossovers, I don't think it's worth the compromise. Unless you already have the coax speakers, then it might be worth the shot. You may have a tough time tuning everything correctly though.

OEM Audio + Reference System.

[Chimera]

I'm going to give it a try.
I have these:
Infinity Reference X REF-6502ix
Infinity Reference X REF-3002cfx
Infinity Reference X REF-075tx

crossover points at on the crx-303
•Woofer Frequency: 20Hz-500Hz
•Midrange Frequency: 500Hz-3.5kHz
•Tweeter Frequency: 3kHz-20kHz
at 3 ohm for infinitys thats 375 2625 and 2250
I'll leave the tweeters inline crossover which is at 2500hz

will report back

I don't really understand your "at 3 ohm for infinity's that's..." What are those 3 numbers?

Also, are the 6502s rated for 20 Hz? Seems low for a 6.5" speaker.
