When turned up past a certian point music blares, On eclipse deck with stock amp Options

[Andason]

Ok, the Eclipse cd deck was installed professionally(cant go wrong with a 1 year theft replacement), and I am almost positive it has an stock amp. I dont think they would have hooked it back up to the amp. So at volume 68+(out of 80) and not very loud, the music is unclean and blares. I do not understand. Should I just buy a new deck thats unamplified and do it myself? Or rewire the speakers to go to the deck?

Dude a little confused after reading your post. But I will try and reply. If you have the stockamp, it may or may not produce more watts rms than your eclipse. There are some decks (headunits) on the market with produce some amazing rms numbers. Now basically you say when you turn it up the sound quality of the music goes to crap, while the sound level goes up. If you are trying to drive your factory speakers with the eclipse headunit's built in amp, than you have two scenarios the speakers are being overdriven and willl be trashed, or your headunit it running out of power. Also if you like having the bass adjustment urned on or heavy bass, and you crank the volume, the speakers will sound like crap, becuase its trying to produce low bass sounds which they cannot handle well. I don't now of any headunits that don't have a built-in amp.

I am not new to the sound area or anything. I understand that turning your music up loud distorts it. It is just ONE certian point I go over when it distorts. It doesnt distort more as I go up higher. It did this with the stock speakers as well. I am gonna open it up back there and look, but I am at work and just wondering for things to look for. I have the bass on -6 as I don't really care for it. The deck boasts I think 55x4 or 50x4 as it is an Eclipse. I'm thinking that they left it hooked to the amplifier and it just cuts out past a certian point because in my 5GC I could go all the way up and have very little distortion and VERY loud mids and highs. Eclipse also makes decks with no built in amplifiers. I am pretty sure Alpine does too.

I know my speakers did that as well, its usually because of the bass coming out of the speaker. Turn down all the bass and it should help the problem. I have bass blockers goign to all 4 of my pioneer 6 3/4'' And i just let my 2 rockford subs take care of all the bass...

Once again, I AM FAMILIAR WITH WHAT DISTORTION IS. I understand the concept of music being loud and bass blaring. However, my bass is ALL THE WAY DOWN(-6). It is at volume 68 it is PERFECT CRYSTAL CLEAR SOUND - and at 69 PURE DISTORTION. One notch in volume should NOT do this. Sorry to be so blunt about it but I keep getting the same responces.

There are some decks (headunits) on the market with produce some amazing rms numbers I don't now of any headunits that don't have a built-in amp.

for the first part i know that some sony or panasonic decks say the have like 60 watts peak and like 30 RMS

well thats a lie...kinda..

that 30 watts RMS that its producing is at 1-5% THD. go ahead read the owners manual it will tell you that in there..........at 1% THD (total harmonic distortion) your speakers will blow.

in the truth its more like 15 watts that they can produce without distortion...

if you dont believe me. go to a stereo shop or something and ask them to show you a 30W X 4 amplifier. i can almost 100% guarantee that it will be way bigger than a deck that fits in your dash. how can a little ass deck produce those numbers but aftermarket amps are so big. thats right the people with the decks arent telling the whole truth

what they do it hook up the deck to a dummy speaker that doesnt produce any sound it just measures wattage and THD. once they achieve w/e wattage that they want then thats what they advertise. they can say that legally because later on in the owners manual they tell you that that wattage is at 1-5% THD.


now for the second thing about no headunits that dont have a built in amp.

sony, clarion, pioneer, kenwood, etc. all them make decks without a built in amp.

the reason for that is it can produce better sound and operate cooler because there is no amp in there.


they arent cheap by any means. probably around 500+ dollars.. but they are really good.


dont think i am dissing you or anything...just replying...

[Andason]

Haha, finally someone who understands the langauge! Do you have any idea why it just suddenly distorts? This is an Eclipse deck, if you know anything about stereos you know that Eclipse is a high end deck. It isn't your sony or jvc that says 60,000 watts and puts out 12.2 watts. Thats why I am confused about the sudden distortion.

i really dont know why it would do that...my friend works at the local stereo shop but its closed now and no one is answering the phone at his house...if you can bare with it tonight i will go down there tomorrow and ask


also if you have a 4 channel amp definitely hook it up to that...and if it is hooked up...try turning the gain down just a tad.

and make sure that the crossover is at a good spot that the speakers can handle without straining.

the only thing that i would think why it would do that is because the gain on the amp is to high...

Thanks for correcting me, wow pretty expensice headunits. Andason, you running any subs? You don't have much bass, but doesn't sound it a little too high with the bass turned down?

[Guest_Matthew_*]

just to clarify again i never meant to seem like a dick or anything

[Andason]

I figured out what was done. The local sound shop that installed the cd player hooked up up to the FACTORY amp. I opened it up today to find both pairs of RCA's being used. I am going to go there tomorrow and make them redo it correctly.
