Ebay is an excellent place to get high end speakers without having to pay for the rent of huge audio shop. For instance, I picked up my Alpine SPX 177r components for $175+ $25 shipping. they retail for $400-500 at Car Toys or Mobile 1. As long as you get them new in a box and from an eBay store, you shouldn't have to worrk about scams.

 

Are you willing to go active, and have a 4 channel amp dedicated to front speakers?

 

Yes I actually have a kenwood 4 channell amp and I do plan on going with rears and front but most people say spend more on the 6 1/2 doors and some decent 5 1/4 rears

 

I've been reading these posts and thought I have to chime in! Before I get on my soapbox, let me say first that I do not have my system in my Vette yet since I am waiting for cooler weather. But, I have had several SQ-based systems in my cars for the past 25 years and though I have not competed often (about 10 events total in California and Oklahoma), I have been quite successful in the events I have entered.

Unless you are using a multi-channel recording such as Dolby Digital or DTS and have the processor(s) to decode the delays, rear speakers are not at all accurate. Just like a concert hall, the car should have all primary sounds coming from the front. Rear speakers will only pull the soundstage towards the rear. And just like a concert hall, the interior though smaller, will have accurate reflections with only front stage. I listen to a variety of music and have many "audiophile-grade" recordings and can tell you this; If you have not heard a great sounding symphony from a 2-channel system, you have not heard a good system! When I first started in audio in the mid 80's, I too thought rear speakers were a good thing. But as I listened to more and better recordings and systems, I learned that rear speakers did not improve a system...just made it louder.

FWIW, The system I have in my VW Jetta (which some of it will be moving to the vette this fall), is a very simple system in regards to size, with one pair of 1" Vifa silk-dome tweeters in the front along with a pair of 6.5" Focal mid-woofers and two JL 10W6V2 10" subs in the trunk. The tweeters and the mids are running off dedicated amplifier channels with 75 WRMS to the tweeters and 150 WRMS to the Mids (JL Audio 450/4) and the subs are running from a single JL Audio 1000/1 amp. And finally, performing the equalization and crossover funtions are Audiocontrol's DQT (30-band digital EQ) and DXS (3-way digital active crossover) processors. I also purchased my own Audiocontrol RTA to aid in tuning the system.

 

Active, This will blow away pretty much any 'budget comp set' and hang with much more expensive ones.


you will need to actively cross over around 2500
These are sold EACH

Tweeter

Woofer

 

In some cases this is true, but not in all. Whether or not rear fill is appropriate for a given installation is entirely a function of the vehicle we're talking about. IMHO, having rear fill in a vehicle that won't support appropriate rear reflection is better than no ambient information at all.

 

But unless the rear is accurately delayed, its not ambient! Any signal that is not delayed will draw the soundstage towards the rear...its that simple.

 

I'm using Alpine's ERA G320 processor which features several enviornment options to reproduce rear echo effects such as stadiums and concert halls in various sizes.

 

I agree with maizen here. but in the end; as i stated earlier, it comes down to your perception of what sounds good.

rock needs bass! bass isn't for rap only think of how deep a drum can hit or even better a bass guitar. and definitely don't overlook midbass if you want the most of your system



i agree with kale here. if you put the money you were going to spend on rears and add a bit more to buy an amp for the sub then that set up (or something close to it) will get you the best sound for the money.

 

however most rock doesn't need the powerful "thump" that is so common in rap or hip hop. This being said, a sub with a huge magnet isn't as essential....however it couldn't hurt. Most of the music you're going to hear will come from frequencies between 100Hz and 2000Hz. Considering this fact, your midrange is your most important driver for music reproduction.

For the most part tweeter only reproduce soinds like synthesizers, cymbals and certain consinants in vocals. Subwoofers cover bass drums, bass guitar and low frequency effects. Most midrange drivers can reach down to the 30-40Hz level but they don't have the power to move as much air as a deticated sub plus they're trying to play a varaity of other frequencies at the same time.

Somtimes when space is limited, you can take a second Component midrange driver (usually a 6.5") and using a crossover tune out higher frequencies making it a deticated woofer. Alpine's SPX 17MB kit is an example of this.

 

listend to TOOL's "prison sex" and then come back and edit your post

 

if you send it to me I'll listen to it

 

I hope we are talking about a women's prison. If not, I am not so sure I want to know where the thumps are coming from. :o

 

Again, that depends entirely on the vehicle we're talking about. My wife's 4Runner sounds better (and more accurate) with than without. My Corvettes were better without. The delay is partially introduced by the path length differences that exist in the vehicle. Some vehicles have huge differences, some don't. A C6 convertible I can almost guarantee won't sound better, but with the top down your stage is now so dramatically altered (and ruined, I'd submit), that the additional output may become more desirable than the stage.

Bottom line, slapping stereo rear speakers in a car for rear fill is rarely the correct approach. That, however, does not mean that stereo rear fill is not appropriate when coupled with other considerations. Is delay the way to go? Sure, if it's available, but that's not the complete answer either. It's a step along the way. Step one isn't necessarily invalid just because there are more steps that could follow.

 

hey spkrboy you really need to get a car computer. I believe sacd is well within reach along with a ton of other tuning options.

ok...back to topic sorry :-)

 

back on subject. Yes, they will fit, but you will need a custom speaker plate. You can build one yourself from MDF by tracing the factory plate and cutting the speaker holes or you can order one from:
