Question about "subless" audio upgrade

('07 Double Cab)

I'm planning on upgrading the speakers in the front and rear doors, and running all of it off a 4ch amp.

6.5" components in the front is pretty much a done deal as there really isn't any other way to go for quality sound IMO.

The rear doors is where the question lies.

I love my storage, and I don't want to part with any of it, nor fuss with any boxes or such fabrication. So my thought is this: Put some shallow 6.5" subs or midbass speakers in the spots for the rear door speakers. I don't listen to music at loud volumes very often and I don't need tons of bass, but I wouldn't mind a bit of punch. The Xterra I had came with a factory Rockford system that had an 8" in the cargo area and sounded great. I could care less about the soundstage in the rear seats, so just pretend no one is going to be sitting back there. (They can fend for themselves )

Will 6.5" subs sound loose and muddy in the doors with too much airspace?

Will midbass drivers be better?

And if I do end up going with actual 6.5" subs, should I get 2ohm speakers for the back with 4ohm in the front (to boost the bass some) or go with 4ohm all around?


Thanks.

 

My hunch is that true 6 or 6.5 inch subs are going to require a proper enclosure (albeit much smaller than a larger sub) to get the most out of them. I don't think mounting them free air (unless they were designed for that) would sound all that great.

I think you'd probably have a better sounding system just running quality components front and back and making sure they were getting enough power. Sound treatments would probably help allot as would making sure your source was high quality.

 

All 4 doors will get tons of dynamat or equivalent.

Source will be Cleansweep --> Quality 4ch Amp, perhaps also JL

I suppose I could just get components for the back also, and just not hook up the tweeters for now, since I don't feel like cutting into the doors for custom locations at this time.

 

What about a good set of coaxials for the rear? The fronts are where your main soundstage will come from anyway but at least then you'll have some HF fill from the back. Not sure if they would fit, but some 5x7's may even work in the back for the application you are considering. I used to have some Eclipse 5x7's in my old truck and they worked fairly well for adding some bass fill. Certainly nothing like a dedicated sub would do, but much better than stock.

 

OK, new question...

Are the component speakers in the front doors (non-JBL stock audio system) crossed over directly from the HU?

AKA: Will I need to run a signal summing interface along with a cleansweep?

 

excellent. thanks.
