ok-i need to get new speakers for my tc. i've heard that you can go 6.5 in both the back and front. i'm trying to figure out what to get-i wanna spend arround $150-$175. if possible, i don't wanna have to buy an amp to amp the components, but if i have to-i guess i'll do it. does anyone have a setup they really like? i was looking at the elemental designs components or the alpine spr17-ls. does anyone have a suggestion between either one of those or something close to that in price?

the EDi's will blow alot of other speakers out of the water!!!! I'm not sure if the 6000s needs to be amped or not....I would think so.....

you can't run components without an amp or you will probably damage your components by underpowering them, so you will definitely need an amp. also, you will get better staging if you only run components up front and remove your speakers in the rear. MOST, if not ALL, competition audiophiles run no "rearfill" in the back. the idea is that you're supposed to hear sound in front of you, NOT behind you... but do what you prefer.

rather than spending $150 to $175 on components front and rear, i would rather combine the money to buy 1 really nice set for the fronts. in order to recommend something, you should first tell us what types of music you like to listen to? i can't comment on the eD components, but their amps and subs are decent, especially for the money.

no ofense, thats the wackest thing i ever heard....

you can not under power....

mostly house and trance. some hip hop. i have a 6.5 memphis prcs highs already, they're just not installed. that's why i want to get another full set with tweets and x-overs.

Actually you can thats how my friend fried his subs.

impossible.

i work in the industry (18yrs experience). it can not blow from under power.
under power just means less output potential.

who ever told your friend this just wanted him to spend more money...
no such thing as under powering...that would mean if you listened with the volume low your speakers would blow...just plain dumb logic....

People can indeed blow speakers by underpowering them... but underpowering isn't actually the cause of death. The final cause is the user turns the gains all the way up, and cranks the volume until they're hitting 20% THD, then the subs just tear themselves apart.

Distortion kills speakers... the human ear is virtually deaf to low-freq distortion... people do stupid things.

So underpower can be dangerous to speakers-- in certain people's hands.

I think he means underpowered being overdriven. if you don't have enough power to run your speakers at the volume you want (most likely loud), you distort the speakers, and distortion is what damages speakers. the smaller the speaker the less chance you can hear the distortion until it's too late.

there are alot of low-end components that only require 20-50 RMS watts that don't REQUIRE an amp.....it may be better by using an amp....but you don't HAVE to have one......EDi's i think you absolutely DO need an amp because you'll never get the needed RMS from the HU (even aftermarket).....

this makes better sense...

underpower on its own will not do damage...but clipping or distortion will wreck havoc...

If you don't plan on using an amplifier for the components you might as well leave the factroy speakers in. you might gain a little in clarity but you will have less volume and run the risk of sending a distorted signal and blowing something. Buy a one good set for the front and get a 4-channel amp to power the whole system.

How do you figure you can't underpower speakers????

Underpowering the speakers means that the voice coil isnt getting the proper excursion (movement in and out of the magnet t). This causes excess heat on the voice coil, which in turn causes clipping. Excess heat will cause the voice coil to burn out.

Are you suggesting that isnt true??

you are so close but still far off....


clipping, is created when the amp is not able to supply the power demand when the volume is turned up. If you turn the volume up very high without the power to back it up, you'll end up clipping the signal coming out of the amp. The speaker will try to reproduce this clipped signal, and if played under these circumstances for any length of time, the speaker will not last very long.

ummmm, how exactly is this:

*not* underpowering it??


Sorry, hit the submit button a little to quick...

I guess technically, as long as you don't turn the volume out so loud that the signal distorts, there wouldn't be any harm (as there would be no clipping). However, if you bought a set of components that were designed for ~ 75+ watts RMS (example, mb quarts Q's, or DLS iridiums) and you were only supplying ~25 watts RMS ( rough guess of what the stock HU is capable of), how loud do you think you are going to turn the volume up before the signal distorts?

finish the sentance... you'll end up clipping the signal coming out of the amp.

the signal quality it the problem when underpowering.
not the lack of power....

figures you'd still miss the point.

Maybe I'm taking this the wrong way, but for a super mod, you either don't seem to be following the rules (no personal attacks in your posts).

Lol, what you are saying:

a person has a car stereo, connected to a cheap amp, connected to set off speakers.
person turns the car stereo up, the amp is unable to create enough power to replicate the signals correctly, and clips the sound (square waves), the amp then sends the clipped signal, amplified, to the speakers. The speakers then melt the voice coil.

So in essence, what you are saying is:

the fact that the signal is clipped is what causes the speaker's voice coils to damage, *not* the lack of power. Correct?

Precisely. It is the lack of power misused that is dangerous. The exact same way people blow out stock speakers on stock HU power, when the OEM drivers are at least 15w RMS, and an OEM head generally produces 4-7 watts...

now you are thinking....(no attack...lol)

distortion and clipping at any power level are what causes the damage...

so, underpowering on its own is not bad for speakers.

now do we dare go into RMS and peak issues?????
12v ratings or 14.4v ratings????
Staging, resonance...

eDi's will sound fine off the stocker in a tC. Did it myself for a day since I promised my parents I wouldn't drive it w/o an interior...and I need sound.

Yes, they'll sound infinitely better when amped, but they'll do fine w/o an amp as long as you don't crank the deck to it's limits. It's a decent deck, but it will still clip.

Oh...and with the whole distortion vs. underpowering.

People without the available power want to get louder...so they turn it up to the point where the wave form becomes square. Meaning that the speaker is supposed to instantaneously move from peak to peak, there is no in between. This = heat = burnt coils and not a warranty issue for any manufacturer.

More power, keeps a sine wave = the speaker is supposed to travel linearly and will disappate heat properly :)

wow, i didn't know i caused all this controversy so let me re-phrase... Underpowering a speaker will not damage it just as long as the speaker is not seeing a clipped signal. but like someone suggested, one may be proned to clipping the signal of a weak amp by turning the gains super high, or perhaps, turning the HU's volume all the way to its peak. for whatever reason, it's better to have headroom when powering components. i hope we can all agree to that, right? the clipped signal could either occur at the amp or at the HU, but either way, what comoponent set is worth buying if you plan on running it off the deck?!?!

now you are thinking....(no attack...lol)

You and I are on the same page....
Thinking never changed, I guess what I was trying to say, and wasn't getting out very well was that:

(A)underpowering speakers will cause distortion and clipping very easily, (plus B) if you turn the volume up too high, (equals C) and distortion and clipping is bad for the voice coil.

I was just trying to simplify things, and didn't mention the B part, in order to avoid an off topic debate about gain settings.

EazyM3, see above post :)

ok-so i should power the compontents with with an amp. what kinda components is everyone using here? i have the memphis highs, what else should i get to balance everything out. i don't wanna spend that much money on all this stuff-i still need to get leather and nav/dvd

sell the memphis "highs" and get the eDi 6000s with an amp.....

i ended up buying the kicker resolution rs6c 6.5 components. http://www.cardomain.com/item/KICRS6C i got them for an awesome price $189 shipped-crutcfield was selling them for $329 and cardomain had em for $349. should i just put the kicker components in the front and then the memphis highs in the back? i have the bazooka sub in the back so the bass is fine. also, what kinda amp should i get? do i need a 4 channel or would a 2 channel be fine? this is what i plan on doing-obviously, the kicker components, i have the oem bazooka sub, i'm gonna add the ddx7015 or the eclipse avn2454 at the end of summer, and trying to decide if i should keep the memphis highs. the amps i've been looking at are the kicker kx150.2 http://www.crutchfield.com/S-UHPm3VWScJ6/cgi-bin/ProdView.asp?g=110&I=2064KX1502 and kx250.2. http://www.crutchfield.com/S-UHPm3VWScJ6/cgi-bin/ProdView.asp?g=110&I=2064KX2502

i don't need to blow my ears out, even now-the stock pioneers aren't so bad in my opinion. i just wanted a little bit better. with that in mind, would the 150.2 be ok?[/url]
