x2! rear fill is a waste of money!

Why?

If you're getting the proper imaging, balance, etc, from your front speakers, THEY will provide the rear fill. The rear fill from a live performance comes from the stage. Also running rears in stereo will hurt the front sound stage and imaging. Do a search on rear fill, you will find many others who say the same thing.

You would be better off getting better front comps for the front, better speaker placement, or more damping/ better install, and also sound deadner! depending on what you need.

yeah two sets of the z's is intense, and way over kill. You should of just gotten a boston amp the 24 or 28 perferably, I have the z6's in the front and that already kills my ears, anything more then that would just be stupid, and ruin the sound stage of the car. You're better off geting the w7 or 555 and calling it a day. The SPZs wont let you down, but two of them is too much. like the other guy said, spend the money on something like sound dentening or better amps... gl.

Not to take anything away from what shpatb said, but if you own or have used a good set of Head phones, you should know why ONE pair will work. The stereo recording is only two tracks. When you listen to a a great recording with headphones you will notice that the soundfield is not from the rear, but from the front. Even though both speakers are directly from the side. This is why one pair in the front is ideal. If you go adding speakers, indescriminately to the soundfield, without DSP, you will smear or blurr the soundstage image. You MUST have surround sound processing, or the extra speakers are a waste of time...period!

Hi guys, thanks for all your replies they've been very useful. Still doing a bit of research into imaging as it is quite new to me as is surround sound processing.

The speakers and amp have arrived now and i understand what you are saying by only using one pair. But do you honestly see me getting back what i paid for these components?? If i am going to loose money why sell?

Return the 4 channel, and get yourself a strong 2 channel, or 2 smaller 2 channel amps.. ex. 2 sundown sax100.2's. Run the 2 channel amps in dual mono to each set, those z's will love 400 watts!!

Yah thats a good idea too!

Those Sundown's are nasty amps. They have some serious power for a 100x2!

 

[zeuolaxxx 10+ year member]

buy some sound deadner too!

 

[n0114692 10+ year member]

Sound deadner already ordered, 60sft on its way... not sure when though :s

 

[shpatb 10+ year member]

400 watts is too much... mine almost blew out with only the boston gt24. I personally wouldn't get anything but the GT24 or the GT28 to run them. The nice thing about the cross overs on those things is that they have small lights that take any extra distortion power from the amps //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif so if you see those lights starting to slowly dim on or turn a little bright, turn it down real quick before the midbass driver melts on you //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

 

[n0114692 10+ year member]

I was think 400watts is too much.. Manual says they are roughly 150rms. I was considering the GT24/28 but i got the JL very cheap and brand new so couldnt say no. I understand what you are saying that 75rms wont be enough but i think im going to stick with this until i can get hold of the 600/4.

The crossovers are huge, they're each the size of a brick.. Literally. Where do you hide yours?

Cant wait to get these installed!!

 

[HCCA 10+ year member]

Actually, the rating is conservative for safety, and warranty purposes. You can feed them up to 300 CLEAN watts, and you will be fine. The GT-24 will work just fine. Though, you said you have the JL amps already.

 

[shpatb 10+ year member]

i put my cross overs in the trunk next to the amps. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

 

[n0114692 10+ year member]

I think im going to stick with the one JL 300/4 for now. Atleast with 75watts there won't be much chance of breaking them lol... Will deffinitely be upgrading in the near future though. Ive been on a few websites and noticed alot of new gear is coming out mid 2008 so will wait and see the reviews on them before i buy anything..

I know shpatb owns a pair of these, does anybody else? Just wanted to know if they're as good as what ive read in a few reviews.
