Has anyone here pulled there rear speakers out and plopped an 8" sub back there for midbass? I found a deal on some ridiculously cheap 8" subs that will handle 250 apiece, and am contemplating doing this. It would entail making my own mounting rings and mini enclosures, and I'm really just curious if it would make enough of a difference SQ wise to be worth it. Thoughts anyone?

 

I've always wanted to see someone do this... be the first and post how it goes!

 

I know it'll fit in there, those rear side panels are cavernous. I'm just wondering if that will even sound that good. Although I suppose it pretty much has to, not much can sound worse than our stock rear speakers.

 

A 8" is nothing I've seen someone put a 10" sub in that spot, of course it was a shallow mount type woofer.

 

Pioneer TS-SW841D's might work well in this application. Free air, shallow mount. 500 watts peak.

 

Certainly possible, but might be a negligible SQ improvement and possibly weird sound stage if you're also adding a woofer. I've never been too impressed with shallow mount 8"/10" subs in the interior/doors. You would also have to install dynamat or preferably a spray deadener to not loose all the sound energy to a rattling fender. I had some 6.5" Boston Pro's on 175w RMS in that location which played between ~40 - 100Hz and those made an awful buzz in the fender with a reasonable layer of dynamat. Added more and better coverage and reduced the problem significantly.

 

Yeah, that whole rear skin needs a solid inch of deadening. I really need to get around to deadening my car, the noise level is terrible.
