Coaxials or Components in the back?

[rdrunner]

For those that have nice sound systems in their 4th-gens which do you recommend for the back. I don't want all the sound coming from the front but I'd like the soundstage to be coming from the front. I've read other places it's best to go with coaxials in the back doors for this reason so the tweeters in the back don't mess up the stage. Coax will save me $100 but after all I've put in this thing that's not a big deal at this point.

I've got the amps installed, most of the sound deadening done, stealthbox hooked up, head unit with steering wheel adapter. I have the components for the front doors and am ready to do those so it's time to get order the rears.

Thanks!

Coaxials for sure. I don't think you would want to drill for another two tweeters.

I had the JBL system so there's the space in the rear for the tweeters but it doesn't seem to make sense to have the tweeters blasting to the front since we're not talking surround sound.

Are you talking about the ones in the very back? I don't think those are tweeters, but I'm not very familiar with the JBL systems.

I meant if you went with components in the back you would probably want to mount the tweeters on the B pillars facing the rear passengers.

Yes the very back. They're very small speakers - the JBL version of tweeters and they blast to the front.

They're at a rather reduced level that I'd hardly call "blasting".

Technically, those "tweeters" are 65mm full range speakers. In the 10 speaker systems, the same 65mm driver is used for the front L/R/C and the high mount rears. There is a small cap on them that blocks bass somewhere in the 150-200Hz range, judging by ear.

Finally, the rear mid-tweeters are not a L/R stereo pair. The 8 channel amp/processor in the Synthesis systems is split LF/RF/C (3 channels), LR/RR doors (2 channels), DVC sub (2 channels)...the 8th channel is a mono mix fed equally to *both* of the rear 65mm drivers.

If you match the front set you will not upset the stage. I did and I think it works. I created a "coax" setup not wanting to cut another hole for a higher tweeter. This helped the mid-bass a lot more than anything else.

The very back I would just un-hook and leave alone. No real advantage will be heard from that distance to your ears in the front.

Thanks for all the tips and very interesting about the tweeter channels. I thought they looked like just full range speakers - like a bose. I installed the front speakers last night. I'd say fishing the wires through to the door was the hardest part. I'll post some picks at some point. I'll need to put some more sound deadening in there. I used the eDead paint which worked well in the back but didn't seem to work as well in the front. Different frequency range I guess since you're only blocking sub bass in the back. Have to get the plastic from rattling too. It only rattles a bit on certain notes but still annoying.

Love the sound. I'm doing this sort of on the cheap but it's sounding great.

HU: Pioneer 4100DVD
Front: Polk MM 6501 components
Rear: probably matching coax
Sub: JL Stealthbox
Main Amp: Eclipse EA4100
Mono Amp: Eclipse XA1000
Wires: RockFos 4guage to fused dist block - 8guage to amps - 8guage ground to another (non-fued) dist block then 4guage grounded to the chassis. (I read you want to ground to the same spot to remove hum, don't know if that's true but I figured it wouldn't hurt if the wires are good.)
Speaker Wire - Scoche 14guage to mains and 12 to sub.

All other hardware and RCA's are Scoche. I think the Scoch stuff is good but the plastic sheilding is way too sticky. The wires don't pull nice and stick together when snaking them places. I ran all the RCA's up the center of the vehicle.

The stealthbox I bought used - it didn't match the color though it was close so I used some SEM vinyl paint to make it match the plastic panels. It looks pretty good, certainly not as soft as original but it's still flexible and just looks a bit more rugged. The amps I got local on Craigslist for $50 each which was a great buy. As for the Polks, they're the ones I just kept going to when I would listen to things. Something about them, they had the voice I was looking for even though others may have been cleaner and more detailed. I almost went with Eclipse but they just didn't move me. They seemed perfect and yet boring if that makes any sense. Focal's and such were out of my range so I never considered them.

I ordered the matching Polk MM coaxials for the rear today. Looking forward to finishing this!

pics?

how did the install go?

where did you put the crossovers?

how did the speakers fit in the factory openings?
