NEW sub wiring help

[Troyziee]

g'dai guys. just after some help in the wiring of my system,
i've got a single 12" running off a two channel (bridged, running 800wRMS) unfortunatly, i've blown the subs voice coil (was second hand to start with) though ive been told i have to turn tha gain down, as the sub is only 550rms, single voice coil. though also wana no if the wiring into the sub i run is correct. its a dual lug terminal on the sub, so two pos two negs, im just running the wires to the outer pos n neg, is this correct?? cause i really dont wana blow another sub.
cheers

yer that sounds rite but if its single voice coil it should only have 2 terminals

[garfa]

you have blown the driver but want to know if you wired it right? what???
it does not matter because the driver will be useless now.
heres a thought, either change the amp so you make it harder for yourself to blow the driver or get a new sub suited to the amp, be it bridged or normal.
silly boy.....

i've already bought a new sub mate, the other one was second hand, so chances are it was already thrashed.
its an audiobahn system, and i spoke to the audiobahn guys at autosalon, and this is the sub they told me suited best.
and i know the sub is buggered now, hence y i bought a new 1, though i was only asking about the wiring so as i dont blow a second sub within a couple of months. ? cheers

[garfa]

the wiring wil not effect the ablility to blow the sub again. the way its being over driven will though. why dont you run the sub from the amp un-bridged?

To better answer your question,
What are the model No. of your sub and amp?

Your new dvc sub has two voice coils hence two sets of terminals. Normally, these must all be connected to operate the sub properly. Need to know what the sub and amp are to help.

g'dai phree,
its only a single voice coil sub, but the audiobahn has dual terminals, not sure y.
its a audiobahn A8002T amp (running it bridged) and a audiobahn AW122N sub. the blown sub is audiobahn AW120T, also a single voice coil, and the old one was 500wRMS and the new one is 550wRMS.
cheers

did your first one, the one thats blown, have 2 sets of terminals?? Whats the model niumber for the new sub? same as the old one?

[phree]

Two sets of terminals for one voice coil, LOL.

The amp is claimed to produce 400wrmsx2@2ohms, so 800wrms into four ohms bridged. Significantly overpowering your sub. Be careful with the gain control and volume and it will be fine. Max out the gain and/or volume and the smoke will come out.

[Troyziee]

lol non of u beleive me bout tha 2 terminals, ill get a pic if i can, there called dual lug terminals, there next to each other, not on tha opposite side of tha sub.
and as for overpowering tha sub by running it at 800rms at 4ohms, i was looking for a higher power audiobahn 12" (within a reasonable price) though tha audiobahn dealer at autosalon told me tha best match was tha AW122N, so thats wat ive got.

we believe that the subs have 2 terminals, i just cant understand why there would be 2 terminals for one voice coil. Only thing I could think of would be for a sub with a huge power handling, like a DD9900 series, so you can hook 2 amps up to it. Posting a pic would be good

[phree]

I believe you. I looked at it on the web. When i checked the sub and amp specs for those you posted.
Just seemed a bit strange at first. Marketing? More is better?

Anyway, as long as you like it, nothing else matters. Just be careful not to let the smoke out.

Cheers

Yeh. So just connect to one of the positives and one of the negatives. Shouldnt matter which one

[Troyziee]

thanks for that help guys.
also just wondering if i've got the gain and that turned right down on the amp, can i have the bass boost switch on? or leave it off? cheers

[phree]

On or off, whatever sounds best to you. Just adjust the gain properly with it the way you want. i.e. If you set the gain with bass boost off then turn it on without readjusting the gain, you may cause the amp to clip at a lower volume. This is not good for your sub.

Personally, I prefer to use the hu eq to adjust this type of thing, not the amp. Fixed frequency boost is only helpful if the frequency it boosts is where you want it.

Bass boost is better for when you're listening at lower volumes, and want the sound to be more 'full' and bassy at low volumes
