I was wondering the mounting depth for the 6.5" speakers for the front and the back doors for a 1999 sport. I was thinking about getting the alpine type r components up front and the type r two-ways in the rear.
Also, I think I have 4" speakers in the dash, I was planning on just disconnecting them when I get my new system or would it sound much better if I replaced them with aftermarket speakers? But the jvc cd player i'm getting only has a 4 channel amp, would i have to have an amp to power 1 of the pairs of speakers?
thanks in advance brewster

The best way to check the depth of your door speakers is to remove the door panel and lower the window. Take a tape measure and check the distance from the glass to the mounting plate. (subtract about a quarter inch just to be safe). I have Boston Acoustic RM6 up front on my MS and I had to make 1/4 inch spacer plates to get them to fit. As for the 4 inch drivers in the dash, I say use the rear speaker out puts from the head unit and just run your system up front. How much do you listen to your system from the back seat? Just a suggestion.

Ok i dont know about the idea about the rear speakers from the last post. If u do that u will loose the sterio effect. Believe it or not u do hear it from the back if u loose those it will sound funny. Chances are if u are using the stock wiring with your new headunit thet are all tied into the front speakers. So that means the door and the dash are wired toghter. They are so close that is the best way to keep the sterio effect. If u are wiring all the speakers with upgraded wires just do the same and wire the fronts toghter its again real easy since they are so close. I would recomend doing this anyway, no sence using the crappy stock wires when u are putting in new speakers! My sport didnt have them in the dash stock so i added some and it sounds better with em! So i would keep em and upgrade later if u want! Lata

Yeah, I will probably run new wires. As of now I still haven't decided to buy new 4"ers or not. I don't really like the idea of disconnecting the rear speakers and just running the fronts- thanks for the input though. I never did find out the depth of the doors but I ordered the speakers anyway . They should sound real good. I also ordered the new JVC head unit that has the touch screen and voice commands, it looks real tight and JVC usually makes good stuff. I am also going to get some subs eventually, need to get some more money first, anyone want to donate to my cause ;D. I was thinking an MTX amp with two, no.....three 12" Alpine Type R's. Hmmm those new Infinity Kappas look nice though, so do the new kicker L7's. What are your all's opinions of those subs? Any good?

Stereo means left and right channel, not front and rear. So the sound from the rear right speaker is the same as the right front speaker. The only way to correct this is to use a sound processor that attenuates rear stereo channels. The reason I suggested using the rear channels out puts for the front 4inch drivers is so that you could have a full frequency response up front (woofer, mid, and high range). This would also allow for the mid to be faded (front to rear) as to not over power the rest of the speakers. I have done this before in a couple of cars that had 4 inch dash speakers stock, just added a component set to the doors. The effect is a full frequency response from the front of the car where most of us sit when we rock out . MTX is one of the best product lines available. The amps are consistently beyond specs for power output and THD response. Just my opinion guys.

Wow welcome to 83 bro! First off i dont know what u are smoking but sterio is all around u! The rear speakers dont get the same signal as the fronts all the time that way when u listen to something that is supposed to go around u it will sound that way. If u run the fronts like u said u would totally loose that effect. I dont know if u listen to dance music but they always have the sound of **** going around u and when u got the system right it sounds like ure in the club. I dont know why u would even want the full range in front of u. If u ever notice the stock locations of speakers u always have your bass type speakers to the back this is true with midbass too! So why have the wooofers to the front? Even in the sport with the front and rear doors the same size u still want the rears to have more bass than the front. That way the front speakers will stay nice and crisp with the high frequencies. If u run mid bass to the front it will drowned that out and sound like ****. The way i have told u is the way to go, i have it done in mine and it sounds great. Not only while i listen to music but when i have the tv on too! Its like surround sound with the tv. Id rather sit in the truck than on the couch, lol. Cuz it is that good! As for the mtx thing not to keep picking on ya but that would be one of the last componet sets i would use, im into audiobahn myself, but the alpines he is looking at will be very good and i wouldnt have a prob recomending them. Mtx makes some good subs but there highs just arnt up to some of the other brands. But we all have our own oppinions on that! Lata

From experince the L7 solo's are the shiznit! I have a set of 10's and they are sick. U may want to get a high powered JL amp to run them though because one 8in L7 can handel the 1200x1 that kicker makes. Clay

OK, After speaking to an audio engineer and music producer, here is what I have found. Stereo sound reproduction means left channel and right channel playback. The stereo format is a 2 channel format which is used to create a realistic image of the sound. Making it sound like it is coming from different directions in front of you. The idea behind using a stereo format is that you use the channels in a way so that the listener does not think the sound is coming from one of the two speakers. So that is also what you need to keep in mind when you are mixing! You are creating a field of sound where the listener is not going to ’think’ he/she is listening to two mono type channels. Anyway, who cares what other people think. Rock on to what sounds good to you bro! (Guess all those years working with car stereo installs and companies like Polk Audio and Boston Acoustics have made me stipud.) Peace. Some decent reference material. www.carstereo.com/help/syst_design.cfmwww.carstereo.com/help/index_components.cfmwww.carstereo.com/rayfes/plan.cfm

Coming from a former carstereo installer as well as a former IASCA competitor....Paintballer hit the nail right on the head- Stereo is a 2 channel (L and R) signal. The right rear speakers get the EXACT same signal as the front right speakers PERIOD.. same goes with the left speakers. Were not dealing with Dolby Digital 5.1 surround sound here.... just a simple plane jane stereo L and R outputs played out through a 4 channel speaker system. YOu will NOT hear an airplane circling around you from front to rear as you would Dollby Digital setup...rather, you'd hear the airplane fly past you from side to side. You'd basically want your speakers to produce lifelike sound as if you were in a real life concert hall. That basically means FULL RANGE frequency response in the front with the lowend crossed over at about 80hz. The 80hz crossover point is just a general setting and may vary depending on the ability and size of your front midbass drivers. Any lower of a setting and the speakers will have to work overtime to reproduce sound that they are incapable of reproducing at a high volume. Any quality component set should be able to handle that even at full volume without breaking up or causing distortion (even the non-Infinity components sound great when powered with a capable amplifier). The full range of sound will reproduce a front lifelike stage- just as it would if you listened to an artist perform on stage. If the speakers are arranged properly... the stage you hear on your dash should replicate the stage you hear at a concert...including the exact placement of every instrument as well as vocals across your dashboard. Rear speakers should be turned down just to the point where they are hardly audible from the front. They should only be there to reinforce or "fill" the front speakers and should also be crossed over at about 80hz. HOw many times have you gone to a concert and listened to the music with your back turned to the stage.. ZERO... so why would you want to set up your system with a rear stage? Do to space limitations, the lowend or sub frequencies of course will be in the rear. Joel, CA

Ok first off i didnt post on here to make anyone feel stupid so i f i did so i do apoligize for that! I have never worked for a sterio compony or shop but i have competed in stero sound ofs and such in the past, and i do hang out with several strieo installers, so i shouldnt be way off base. Like u guys have mentioned everyone's ears are different and just do what u think sounds good. I just totally didnt understand the idea to totally loose the rear speakers. Maybe the fronts and rears do get the same signal but loosing them will definatly hurt the sound stage. Even at a concert u get reverb from behind as the sound bounces off the rear of the venue. With my headunit i can adjust that by timing each speaker so in that case not fronts to backs dont get the same signal, Thus increasing the suround sound. My set up may not be 5.1 but by doing this u can fool your ears to beleive it is. So anyway i hope the creater of this thread can make sence out of what was said here and hook up his system. Again i do apoligize if i pissed anyone off! That was not may intention. Im just trying to help as are we all! Lata all!

Sirlordoz- sounds like you have one heck of a HU running you're system. The delay or timing control feature you have on you HU is meant to be used to either compensate for poor speaker location (that some manufactures "force" us to use, or even to create a delay from the rear to simulate the reverb (sound bouncing off of the rear wall and back) that would be heard at a concert hall. I have a similar set up with my Clarion EQ/Crossover/DSP module that's hooked up to my HU. I can control the width and length of my truck as well as reverb, effect, delay, etc. Even with that- the rear speakers should be turned down to the point where their sole purpose is to reinforce the front sound stage and create a sense of ambience. I'm not here to get into it with you as I respect you're creativity and what you've done with your truck- i just wanted to clear things up as far as stereo sound being simply a L and R deal (stock) and not a surround sound type setup (and i'm not smoking anything either ).

Thanks bro! I know sometimes we all need to put the ego aside and just listen , god knows i can learn from doing that! Like I said im just in the sterio as a hobby, and the custom stuff is what i do for a living. I just hope i didnt stear anyone in the wrong way. I do run my set up with the rears lower than the highs like u said. It just sound so wierd if the rears arnt on. Not only that but i want the people in the back to be able to hear to. The one question i have is i want to be able to se the same sound stage in the rear but i am afraid it will mess up sound from the front? And if it is possable how can i do it. I figured i can do the same by making pods to sit on the floor at the rear pass feet. And hook those to the same chanel as the front speakers and then wire the doors as the rear. And then even having another set in the hatch area fro more rear fill. Just wondering what u guys coments are on that! Thanks lata

Unfortunately, there's no way to accurately reproduce a front AND a rear sound stage at the same time. The will basically interfere with one another. In competition, the sweet spot would basically be the drivers seat. All of the mics and such are set up there when they test for frequency response/and or SPL of your setup.
