Default Speaker up grade.

Hey guys I'm thinking on up grading my O.E. speakers. I don't want to install a sub woofer, but I do want more bass. I will be using the O.E. head unit. 2006 Civic LX. Any insite?

dont expect to run any kind of decent speakers off the stock HU. you might want to also list a budget for these speakers.

So, how many watts the O.E. unit have? The real reason I dont want a sub in my truck is, I here too many people with truck lid rattle It just bugs the crap out of me. I really dont see a placement for a sub in the LX. I'm open for any insite onto a system for the LX. Thinking with the Pioneer DEHP9800BT for the head unit. Any help would be welcome.

Factory HU's are rated at 5-8 watts.

Replacing the HU will make a bigger, [and better] differance in SQ, including bass response, then replacing the speakers, you will be surprised at hoe good the stock speakers sound when driven by a "high power" aftermarket HU.
Next step would be to replace the front speakers. 94

I would have to disagree w/ this statement.....speakers are always the quickest way to increase the quality. you have to have an extremely trained ear to hear the differences in amps. and I go back to another post I made.....a 3db increase in loudness requires 2 times the power. you're not going to get this type of power from an aftermarket headunit vs. the stock headunit. at most you'll get about 10-15 clean watts/channel from a headunit. the stock deck...maybe 5? headunits with claimed 50 watts a channel or other such nonsense.....is just that...nonsense. the distortion at those levels is absurdly high. this and the fact that running all speakers off a head unit isn't going to give you the sound you want. invest in a small amp and some speakers (even a 50x4 or 50x2) and you will end up with something you're truly happy with.

First you need to stop posting Second, find out the information that you going to reply to a post with first before you post and spead misinformation.

Now can you tell me why my old pioneer dehp-80mp put out 57 rms per channel rms when it was rated at true 60watts per channel. Could this be because it was a true high power headunit. That had a extra amp built into it that required you to run a power lead straight from the battery? Why don't you ask rightiousfire. I sold him one

Now can you break it down for me and tell me why would you expect better sound from adding aftermarket speakers to a stock headunit. When your adding a speaker that requires more power then a stock?............. Now we know the stock speaker is a low watt speaker because the headunit is a low watt headunit. Why would a car manufactor put a speaker in a car thats not matched to its headunit. They would not because it would give wores sounds then it does now. Any sound improvement would be lost when you try to crank it up to get the volume that you had before and you won't get the volume with the new speaker because the headunit does not have the power to run the speaker with the right rms. Now you have wores sound now then before. Changing the factory radio that has crappy power output and soundstage with a aftermarket headunit with a built in eq, more power, and a better design will give you better sound then the factory unit. Unless the stock speakers are blown from being abused.

Did you even read what you wrote?

nope you didn't. You saying what I am telling you right now. How is the radio going to push the aftermarket speaker?


Lastly you did not say this.

if you look at the first JL it's rating is 83.7 and the 2nd one is 87.

you can easily see why the idq15 will be quite a bit louder than the JL's....you've got a difference between 10db for the 15".

you'd need an amp 30 times more powerful to power the JL's to get the same loudness as the image dynamics 15"

please don't ask me why I decided on the JL 10w7's for my stereo.....the single dumbest decision I've made for my stereo.

Fcm said the correct version and corrected you with knowledge that he gained from working and installing from the 20 or more years that he has put in the game. Not all the people that that post in here are noobs in car audio and security. There some people that are experts installers that lurk this fourm and post to help people out. And we too own hondas/acuras. If you quote one of us you better have the knowledge to back up your claim

The only thing that I agree with you is in your other post. that your never going to hear what a sub will really sound like in a boom room. unless you try it in the car. It will never sound like that in a car. You can make a $20 sub sound like a rocket ship in a boom room. I use to make CC profile line sound like the could win a spl contest in my old boom room.

this is only assuming your amp is sufficient to power them. I've gone through several pairs of speakers but it wasnt until i changed amps that i saw a huge difference in the performance. while a good speaker is important, so is a good amp, its all about balance. one without the other is a waste of money.

ok you have an oxymoron here.
you DON'T want install a sub....but
you DO want more bass........hmmmm

small speakers that will fit into a stock location do not handle the power nor do they have the capability to produce bass. they do, however, have the ability to produce midbass.

so now...tell me what you want more of.....
bass or midbass????
if you want bass....you need a dedicated sub

if you are keeping the stock deck...changing out the speakers will yield better quality sound and perhaps a little bit more volume due to the aftermarket speaker's prolly having a higher sensitivity than stock drivers.

stop posting?....sorry, that's not an option Hitler what is possible is checking my facts a little closer.

why of course I read what I wrote.....I wrote it. we're all not perfect you know...we humans (and in this case me) fuc* up sometimes.

I stand by my statement....buy aftermarket speakers and an aftermarket amp and you will have something you will truly be happy with. This is not even a debatable subject.

and yes I already made a post saying "oops I was wrong" on the 2x the power thing.

^^^^^^ yes.. yes.. I am hitler. I gather all people that have wack audio system and destroy them. Send them to there burning hell were they belong.

Go ahead and stand by your statement. Which shows everybody that you have no ideal what you are talking about and have no clue about. Go ahead and amp your aftermaket speaker with a bad sounding stock headunit. Its going to be a louder poo sounding car unless your going to shell out a nice sum for a jl audio clean sweep. Which cost as much as a deciet aftermarket headunit with mp3 and wma format and a remote.

Also you should edit your post above and say that fcm said it and not you. Don't take credit for something that you did not say.

To the op, sorry had to rant on this noob for stepping out of line. Now does your car have the 7 speaker set up. And what is your budget for this system that you have instore.

Replace the stock head unit before you do anything else, you would be surprised by difference it would make with the factory speakers. However, if you are planning on buying a cheap Wally World set of speakers, then don't worry about the replacing the head unit because a cheap set of speakers are no better than the factory set.

The key to a good sound system in your car is a nice head unit.

I run an Alpine HU and 4 Eclipse 6.5" 2way speakers, [tweeters disconnected on the rears] I have used my car as a demo car to show what can be done without off-board amps and/or subs.
More then a few times I have been accused of having a hidden amp and sub, or the rear speakers are really a pr. of subs.
Although I will not win any "sub bass" contests, bass response in my 94 Integra is very good, as is the SQ.
The Alpine CDA-7893 has something to do with that, a true "high power" HU, and a host of other usable features.

The one thing that has the greatest effect on SQ, and critical for good bass response, is the speaker installation.

My front speakers are installed on custom MDF speaker housings, [replacing the stock plastic ones] with extensive Dynamating, the rear speakers are installed in custom MDF and fiberglass cabinets, [replacing the stock mounts] much less Dynamating was done in the rear, both sets are in their stock locations behind stock grills.

As I said on previous post, the single best improvement you can make is a good quality high powered HU, just replacing the stock speakers will do very little, maybe better highs, sometimes the SQ is worse then with the stock speakers, remember it would still be the same source, so exactly the same power and signal would be going to the speakers.

Anybody that says different does not know what he/see is talking about, and they would be the last people you should take advice from. 94

Default Re: Speaker up grade. (fcm)

you wouldn't believe how good my dynaudio 340's sounds with a high power HU.

anyone want to buy my arc audio XXK's? I'm tired of them.

ok, ladies. many many years ago in my teens I decided to build some home speakers....focal tweeters and peerless mids & woofers. crossover from parts express. read a few chapters from the-speaker-design-cookbook and (unfortunately) chose an enclosure that was well beyond my skills as a 15 year old whose woodworking skills were basically non-existent. nevertheless I got through the project w/ my triangular enclosure.

The first thing I did after finishing was hook them up to my dad's combo turntable/8'track stereo receiver. I had heard the sound coming out of that stereo for years on end.....we worked together in our garage for forever.

call me crazy or say my ear for sound sucks....but the minute I hooked up those speakers to that stereo I was so excited to hear what it sounded like....trust me, I had never heard anything ever like that come from that stereo once I hooked up my speakers.

hooking up a nice receiver to those ****-azz speakers wouldn't have come close to the sound w/ my homemade speakers. now, what would have sounded the same....if I would have cranked-it up even to 3/4 volume.

at low volumes the combo of homemade + **** amp made a world of difference.

I will bet my salary that hooking up a mark levinson amp to my dad's old spekers wouldn't have sounded even remotely close to the SQ of hooking up my homemades.

again, imo this is not even remotely close to debatable. here's a challenge

take a mark levinson amp and hook them up to a pair of bookshelf speakers from a $299 sony system from wal-mart.

then, take that same system and instead hook them up to, for instance, a pair of high-quality set of bookshelf speakers or &lt; pick &gt; .....at low volumes...again the sound difference won't even be debatable.

and don't even say I didn't mention earlier it was at low volumes and not max. there is NO ONE seriously into SQ who runs speakers off their deck. period. you will also never be able to hear the 7-drums on the IASCA disk as they were meant to be with some random speakers running off a high-powered HU w/ sound emanating from your legs. you're going to have a low-soundstage rather than one that sounds like someone is playing those instruments from your hood as you would experience if you were in a concert hall listening to an orchestra. not having a single point-source for both mid and highs (my tweets are in A-pillars) gives a rainbow-effect...highs up top...mids down low. this is only noticeable for certain songs but nevertheless I can still hear this effect of this placement. it's faint but nevertheless it is noticeable on some songs. i would consider my ear at a mid-level of being 'trained'....if my ear can hear the difference on particular tracks the trained ear of a judge will surely detect a problem. Soundstage is definitely raised though and with time-correction it's thrown to center of hood. Relying totally on time-correction to compensate for unequal path-lengths is not my favorite option either....nevertheless I'm really happy w/ my stereo at the moment. Scan-speak, ID subs, Sinfoni phaser pro and stuffing some 8's in my doors + tweets in a-pillars crossed over high will be my next improvements once a few 60-70 hour weeks and per diem are under my belt body-melting-stress does have its benefits on rare occasion.

now, in a car....I'd take a lesser-quality speaker installed in the right locations any day over the best-of-the-best speakers installed in, for instance, the stock locations. see, we do agree on some points Or for that matter a set of quality speakers (let's say focal utopias) that are only listenable with an EQ. the last time I walked into a high-end audio shop and saw an EQ was never. and yes, I know the acoustics of a car are totally different than home but nevertheless....EQ in a car is not necessary w/ the right speakers. the sound quality of no EQ in your signal chain is definitely noticeable....it's why I no longer have one. these speakers are living a happy life in my closet along w/ my 1/3 octave EQ waiting for me to build an SPL system in an unpurchased Regal....i'm willing to live w/ this for an SPL focused system.

"you wouldn't believe how good my dynaudio 340's sounds with a high power HU."
Well duh.

As for the rest of it, no one here is saying that aftermarket speakers can't improve SQ, but an aftermarket HU driving the stock speakers will make a much bigger differance in SQ then aftermarket speakers driven by the stock HU, at any volume level.

Also if you have not noticed we are talking about car audio not home audio, they really are two different animals. 94
