My sub (type X struggles)

[Imshirazy 10+ year member]

Hey all... I sold my type X a while ago because I needed the cash, and I bought another one (used) for 160. It came in a box that fits the spec for an alpine 10 inch type X, looks about .75 cu ft. Anyways...after listening to music with it, it seems to sound kind of crappy, some songs were fine but some sounded terrible.

I am using an autotek sx-777 for now (until I can get another mm1000.1d) to power it. This thing has a total 1080rms through 7 channels, 420 of which is for the sub channel at 2 ohms. The power wire is 4 gauge, the ground is 8, and the car is stock setup (no new alt or dual battery). Honda civic 2000 ex, i believe the alt puts out 75 amps.

Anyways...I took the sub out of the box and noticed only ONE voice coil was hooked up...am I wrong or does this damage a sub to hook up only one voice coil? well after being real pissed off I paralleled it and put it back in, but it still doesn't sound as great as I was hoping. Does anyone have any idea what might be the problem? It sounds great at lower volumes like around 30/60 on a pioneer deck ( I use the 7600 right now) but above that sounds terrible, even though the speakers still sound fine. On some songs though, it'll do 40/60 perfectly fine, but TOO many songs sound crappy, on both bought cds and mp3 cds.

I was thinking it might have to do with the ground wire being too thin for what the amp takes, what do you guys think?

Thanks for any help...

you ****ed up your sub..one VC hooked up = only half of your subs cone was powered prob ruining it...worse case scenario(most likely)

also you hooked it up to all 7 channels??? WTF no dont do that only the sub ones...**** waht were you thinking bro

edit: yes your ground is too small go buy 4ga

Yeah that's what I figured, which is why I was pissed when I saw it, because I know using only one voice coil voids warranty for most subs, I couldn't even believe what I saw..

So you think that the voice coils are basically damaged?

prolly no damage done, but run it with both coils from now on.

might not be take it off all 7 channels and only use the sub channels on the sub...unless i misunderstood about all of channels being on the sub:uhoh:

one of my friends is running a 12" type x and it sounds like crap too i hear they dont get real loud either but he has the right size box and amp and it sounds shiitty

type x is a low lows monster, needs powa tho

That's the amp

it's like 2 or 3 amps in one

channels 1-2 and 3-4 have level control and hi pass filters. 5-6 have their own level control and bandpass etc tons of features. channel 7 is meant for sub only, and even with the others unhooked, i think it can only get 420 rms @ 2 ohm

Also, when I took the sub out of the box, it kinda smelled like something had previously burned...maybe I was wrong, but there was also a small amount of dust in there. It smelled real similar to an autotek a friend of mine had burned a while ago (mosfets blew), but I couldn't be completely sure, you could only smell it if you put your nose directly next to the sub.

I just don't want to have spent money on something that blows :/

Because when I say it sucks, I don't mean in comparison to the stuff you guys are used to like DDs etc, i mean like...it gave off a reverb sound (sealed box) and like it struggled to play some notes, but the notes weren't far highs or far lows, i think it also had a small portion to do with the music

why is the ground 8 guage?

 

[Imshirazy 10+ year member]

Only available wire I had, when all my audio was stolen a while back they left nothing but wire, so I gave my ground and a bunch of other stuff to a few friends.

Do you think a larger ground would help in this specific scenario? I touched the ground and it was still pretty cold after being run for 20 minutes, so I wasn't sure if the wire was too small

change it to 4ga and yea my friend idk if he blew his sub but his has that same smell now we havent been able to try it because his amp blew and thats almost what blew his sub

You guys are retarded.

One voice coil is fine. It just lowers power handling ability and changes Q. Not that I'm advocating using just one coil, but it's not going to break anything, nor does it provide "uneven" power or any of the other BS the morons above mentioned.

you sound like shit and it prob a shitty install shithead

well from what i am getting you only had 420rms going to one of its voice coils? Wouldnt have fried it with that little of power unless it was clipped of course. The reason is it lacking in the higher volume is because.. you only have 420rms on a 1000 rms sub. Throw the amount of power at it that it wants and you will see a world of difference in the higher volume range. I had to same problem with some home audio speakers I had. Only had 100 watts going to a 400 watt cabinet speaker.. tweeter and mid was find but the sub was really hurting especially at high volume.. got a gemini amp that put out 400 watts and my problem was solved.
