Speaker sounding ..distorted

[Deutscher]

Making new thread for new issue:

Me - The DD Linears, the tweeter connects to the speaker, is there a certain way to attach the cables? There's 4 prongs, 2 positive & 2 negatives. A positive & Negative for each the Woofer and Tweeter - does it matter which positive & negative prongs you use? ie. should the inner prongs (1x postivie & 1x negative) be used for the woofer and then the outter prongs for the tweeter? or can it be mixed around? (I think it was mixed when I pulled them off, so I've mixed them up again).

HoldenBoy - Yeah the DD Linears use a smallish capacitor type arrangement on the tweeter wire if i remember correctly.
No theres no particular way to connect the tweeter up to the woofer, its there just to make things easier.

So as long as the Tweeter & Woofer has a positive & negative each then it's fine. Both positive/negative prongs are the same?

Edit: Reason I asked about the RCA's etc. is because when I turn my deck to vol.20, the left speaker sounds like it distorts, it's fine until bassy music is on. Either way it wouldn't have anything to do with RCA's cause the right speaker sounds fine. That's why I asked about connecting the cable/tweeter to the terminals. The speaker never worked so I dont no if it's the speaker itself or something else. I had run new speaker cable from the amp to the speaker itself - so the cable should be fine.

Edit: Kind of sounds like the speaker cone is hitting something but positive it ain't. Sounds like it's excursion is being put to the max or something. But 1 channel couldn't put out more than the other.... and the deck is default (apart from hiphop/rap EQ). I know preset EQ's aren't great but it wouldn't affect 1 speaker and not the other. I don't care too much for these speakers cause I'm getting new ones eventually nyway... just annoying having 1 good speaker and the other sounding bad.

> Swapperd the RCA's around like Alberts had said = Didn't change anything to my knowledge (didn't really expect it to either).
> Took of door trim to see if the speaker is hitting the trim = nothing changed.
> Tighten the spacer to the door, Tightened speaker to spacer = nothing changed.
> I switched the positive & negative terminals between the woofer & tweeter (so positive went onto the other positive) = nothing changed.

I brought some cable from SuperCheap - some cheap brand, 100% oxygen free, up to 300watts etc. (Don't think this could be the problem). Ran cable from under driver seat - along centre console - behind deck - behind glovebox - into door. Power cable looks like it runs from firewall straight under carpet to under the seat (didn't think this would affect it either).

My next speculation is the amp, maybe dodgey channel. I'll try switching the channels around and see if it changes anything. I don't think theres any dials to change a setting for one channel only.

The tweeter makes a strange noise aswell. Maybe that side is getting too much power & distorting? I turned off the EQ's and it still done it. It's not even on bassy music... I tried Kings of Leon aswell. Strange thing was... when I got home yesterday I had a listen to the speaker.. it sounded clear so I left it... driving this morning I could here it all the way to work!

Today in my lunch break. I:
>Took out drivers seat to get to Speaker amp.
> Looked at my wiring - Both ends were correct - Amp Negative went to Woofer Negative, Amp Positive went to Woofer Positive.
> Switched over the channels, Left speaker from channel 1 to channel 2 - Nothing changed. Channels are the same.
> Noticed that the Filter (80Hz) was set to Off - So I switched it to HPF (until I figure out how to use my Alpine 9887 - better to have something on) - No difference.
> Looked over the Woofer, I saw no tears, cone was fully attached, I see no signs of burnt out or damage at all (apart from a scorch line on the back of the cone where the wires had touched the cone (but no holes etc))

So I am out of ideas what could be causing this speaker to distort while the other one doesnt.

Any Ideas? I'm taking it as it's blown.

EDIT

Hmm, not too sure......probably a speaker fault.

Lol. I've checked everything I could think of, just thought if they were dead that there would be some sort of sign.

Edit: or atleast only the woofer or tweeter would be dodgey, not both together.

Means new speakers already!! Speakers were further down my list of need to buy with no money.

Yeah it is strange, maybe put a multimeter (set to ohms) on the amp speaker outputs while the system is off and when the system is playing music, and drastic differences in between the two sides indicates a problem.

My cheap cable I brought was very thin, very fragile aswell.
Is there a standard to use for speakers? AWG I mean.
Is 18AWG too small? should go for 16? is 12 too big for speakers?

Edit: 1side is about 4-5m length and the other is like 3m length.

Every application is different, so IMO theres no standard size for speaker cable. It depends on the amount of power given and the amount of power the speakers can take, along with the length of the run.

18AWG is not "too" small, but you should get better performance from larger cable, 12AWG is usually only for subs / VERY high powered fronts (200wrms+ amp power).

I'll be getting some SoundStream TRC6n's again for my MR2. They are rated 200rms. So... should I get 12AWG?
