Thanks for the advice... ive been hearing a lot of people tell me how important it is to use sound deadening. ive gotten a few reference to raamat, ill plan on using some anywhere I mount a speaker and from the sounds of it, especially in the doors. I like the idea of using the HU to power the rear coaxials.

two questions concerning that,

1. do i need to have a reciever that can adjust for differences in time? my logical thinking would be that since I have one signal that goes through an amp and then to the componenets, and another that goes driectly to the coaxials, ill have to adjust somehow for the differences in time otherwise id get some sort of echo effect. is this an issue?

and

2. i keep hearing to run component systems "live." from what I understand that would mean that I would want to use a four channel amplifier to run individual channels to each tweeter and woofer seperately and eliminate the external crossovers entirely. can I get a link to somewhere that would better describe the details on this? i mean, hooking it up like that is simple to me... use the amplifier crossovers to set the desired frequencies for the tweeters and mids individually, but Id like to do some reading on the benefits of this "live" setup. again, thinking with my own logic, I can see where youd get more power to the individual components, and perhaps cleaner since you eliminate splitting a channel and also eliminate a crossover that could degrade sound quality, but id think the external crossover on a nice set of focal's or hertz's would be a better design, specifically engineered for the components they come with; over the crossovers built into the amp.


I just checked out woofersetc, great prices there. I like the fact that the pricing rivals what id see on ebay and its an actual retailer. ive also checked out a place called millionbuy.com, is there any horror stories or warranty issues with that place?

thanks a bunch guys. im learning at a pretty rapid rate out here, and I am grateful for that.

The qforms are attractive looking, but they are very thin, poorly built, and by the time you get done modding them to work well, you've got more time and money (way more money) in them than if you just built a set for yourself.

From what I remember, the doors can easily fit 6.5" woofers and a tweet as well. Teach yourself to do a bit of fiberglass and you'll be miles ahead of where you'll end up with the qforms.

thanks nismo, I appreciate you following this thread.

ok. ive been doing my homework. and ive found:

1. ok, you were right. I admit it.*sigh*.
I personally tracked down some Q-forms for my car and looked at em. I would build a speaker enclosure out of play-doh, duct tape and silly putty; spray paint it bright pink with green polka dots and perform the install with a case of beer down before I'd mount 500 dollar speakers in those pile of sh*t poor excuse for a solution. I was told, however, that they "sure do firm up when you get em installed, though."

2. I've narrowed myself to either:

Hertz HSK-165's; $330
or
Focal K2P's; the "upgraded version" for $750.00

I keep hearing great things about the hertz HSK's. that they'd blow my old infinity kappas out of the water. on the other hand, i figure the best place I can spend my money if i can afford it is the front components. but, that is a lotta cash for me to just blow. in short,
to make up my mind, I'd need to know that the focal's were really, really something special. for 750 bones id better sh*t a brick everytime I turned the stereo on. women jump into the street and tear their clothes off. the world to turn a little slower. that sort of thing.


3. I can get:

Audison LRX series amps
or
JL audio "slash v2" amps

for almost the same price. is one commonly known to be a better amp than the other?

and also, I can get ahold of a Tru-tech billet B-475 amplifier for 650 bucks. again, is it really that much better than an audison/JL for someone who just wants really nice SQ? or am I just wasting my money on something that ill never be able to really hear the difference of?


and the rest of the details, i figure an eclipse cd-5100 deck and the subwoofer ill determine when i get there, but tentatively, a 10" w6 JL in a sealed box.

I've always liked Eclipse decks, but don't know one model from the next on the newer ones. As far as JL vs. Audison, I don't know where to even point you to get the right answer. JL has some cool technology going for them, and Audison has a great reputation (IIRC), but beyond that I have no idea.

Personally for amps, I am looking at the Kicker SX amps. They come with a very impressive DSP built into them, but unfortunately my budget is nil and they are likely too large to install where I'd like to put them.

I used to know what amps were good and what weren't, but I've been out of the game long enough I don't know what's out there any more. Best I can tell you is good luck...and trust your ears.

I've got a 95 z28 and I would certainly recommend some sound deadening.

ive got a few areas im throwing some sound deadening in, like the door, rear fenderwell and front footwells. it is a pony car, and I expect it to be loud.


as an update, I've decided to pick up the HSK 165's and a tru-tech amp. im getting a great deal on the amp and a so-so deal on the speakers. im a little wary of spending the heavy cash on an amplifier- but it came down to a point where it was 200 bucks more than an equivalent JL audio amp and for that ill jump on it and see what it'll do.

I am leaning towards the alpine 9887 after doing my homework. it seems the eclipse 5100 doesnt have the tuning capability that I want, and the step up, the 7200, is not only backordered but it has no internal amplifier so that wont work for what I want it for. to top it off, I found a source for the 9887 that brings the price below 300 bucks shipped, heck, I cant beat that deal.

its about time. im pretty much fried :cwm16: from spending the past three weeks reading books, talking to people, travelling to audio shops, and doing as much research in general as I can.

That's ok though. Much better to be overprepared than to jump into it, spend all the money, and find out you would have been happier going a different direction. Most kids learn this by their 3rd or 4th setup.

i did an install in... hmmm think it was a 98 z28. 1 pack of raammat (62.5sq feet) pretty much did the trick. and yeah.... i'd say screw the qforms and either shell out the $500 or whatever it costs to have an installer make some custom glass pods... or... if you feel comfortable with glass... do it yourself.

and go with 6.5 components all the way.

yea glass work is fun if you like hard work, but if you can't handle building a subwoofer box, then don't attempt fiberglass work, it's much worse than wood work, and quite expensive now, inflation doesn't help either.

I buy all my fiberglass stuff from http://www.uscomposites.com/ and I reccomend the B-440 polyester resin, it gives you the extra play you need, and if you add more hardener it'll set up as fast as you like without problems, do NOT under any circumstances ever buy the crappy resin from home depot or lowes, that stuff takes forever to dry, it doesnt sand smooth at all, and it sucks to work w ith.
