Anyone replace their front or rear speakers with subs? Options

[Xander_X]

I have the 6 speaker stereo system and I want a little more bass. Just to get a full sound out of the audio. I was thinking of replacing either the door speakers or rear speakers with 8" subs but I'm afraid that I'll loose too much mid and high. Has anyone done this, and how does it sound?

And adding a sub and amp in the rear hatch isn't an option for me. I really don't like them taking up space or having to remove it if I need more room.

I've admittedly just become very cynical in my "old age" about parts and the way things look. I've been "tuning" imports for 15 years now, before The Fast and The Furious was a twinkle in some writers eye. Yeah, I went through the PepBoys phase, I went through the "looks and sound" phase, then started pursuing performance, with little attention to looks (besides being clean obviously). Now, I just want everything to be perfect and the way it was made to be.

My uncle has a warehouse with a first year Viper, a 2004 Viper, 65 GTO convertible with a hurst package, 72 Olds Hurst (complete frame off), 87 Grand National, 87 Grand National GNX edition with the plastic on the seats and window sticker on the window still, some crazy rare 50's Chevy pickup, some rare edition of and RX-8 they only made 120 of ... and more ... I've been hanging out with him a lot the last few years and he's the same way. Wouldn't dream of putting something aftermarket in any of them unless it was the only option (though neither of us are opposed to replica parts if a good OEM one is not to be found). So I think he just rubbed off on me. You start to learn to appreciate the car for what the company saw it as and not want to alter it more than the company allowed for ... that to me includes parts offered in that vehicles generation (in any country), and that company's aftermarket brands and affiliates; in Toyota's case, TRD, TOM's, etc
