so i jsut got my audiobahn A8002T amp its 800 watts RMS at 4 ohms and i got 2 12" Audiobahn AW1206T subs that are 4 ohm DVCS,i have them wired up at 4 ohms and it works fine with my lanzar amp but when i tossed in my audiobahn 1 the subs them self get really hot and the amp is hot aswell,and the amp has a built in fan,also hte amp is mounted on my backseat and the seat is always folded down when its on,what could be wrong??i have my subs wired up like this
maybe its just me but doesnt it seem like im only using 1 of the voice coils o each sub?,like the 1 + wire connects to the - on the otehr side but theres no signal goin to that wire.if that made sense

Basically, the signal is going thru both coils by way of that wire. You do have the positve to one coil, and the negative to the other coil, right? Then another wire to the two remaining terminals between the coils?

he's running the coils in each sub in series which would be 8 ohms per sub, then the 2 subs are in parallel with each other which is 4 ohms total load on the amp.

looks good to me man, should work, just make sure all your switches are set right and don't turn the amp up more than 75% and it should be fine. Also double check your wires so that they are the same as the pic.

my Alpine V12 ran 2 12' RF HE2's without a problem, never overheated once, barely got warm.......

I would assume that you don't have the gain on the amp way up?

Wiring is 4awg?

I've been hearing that the Audiobahn amps are prone to overheating...... never known anyone with an Audiobahn amp, but that's just been what i'm hearing :)

I was just trying to make sure he didn't have one coil from each sub connected to the amp, then a wire across the other coil, because of what he said.

you have the amp ohms down to low. you have two 4 ohm speakers parallel in the box that makes it 2 ohms at the amp. then you bridge the amp and that makes it 1 ohm. well the amp is only 4ohm stable. so there is your problem. either un bridge over thing or get 8 ohm speakers or get a amp that is one ohm stable.

each sub has 2-4 ohm coils. he's running each set of coils in series, resistance adds up in series so each sub is at 8 ohms. then he's got the subs in parallel w/eachother which since resistance splits in half in parallel (as long as there is equal loads) he's running 4 ohms. :wink:

and BTW, i forgot about the whole power thing. Make sure you've got a damn good ground (I'm using 2- 4 gauge lines on my 1600 watt Orion) and a good power wire, at least 4 gauge. The remote wire dosen't matter as long as it can give 14.4 Volts @ .05 amps (22 gauge).

yah, i had to look at it a few times. It's been a while since i've wired one up. I haven't messed with my system in about 2 years. :p

well its wired proberly,i got the ohms checked and it was reading 5 ohms,but that was when i had the 1 sub inverted but i put it back to normal,also i have Orion 4 Gauge wire all around with the ground from hte battery to the chasis upgraded aswell,and i had the gain to about 1/2-3/4, the subsoncic filter was at like Min(so 20HZ) and the HPF was at like 1/2 and the LPF was at about 1/4,1 shop thinkgs i might ahve 1 coil blwon and while its playing its throwin out different ohms??

yeah only difference is that on my sub i have an input and a output spot for each negatove and postive post,so i can attach 8 wires to each sub but only 4 are inputs spots,in the pic the silver wire comin outta the box is + and the blue wire comin out is - that other silver wires is goin form the _ to the + on hte sub,

ohh yeah and i dont have the sub inverted anymore but when i did i switched the - and + on hte sub,but i pout them back to the rigfht spot when i mounted it the same way as the other sub

thats 8 gauge wire
and i took my subs outta the box and tested each vocie coil and then read inbewteen 3.8-4 ohms and when i wired them back up i got a 3.7 ohm load,so im thinkin its not my subs that are the problkem its the amp,casue my subs never smelt or produced heat before

well here is what audiobahn told me

"The problem is that 3.7 ohm load. While it is just under the 4 ohm stable rating, that .3ohm per side adds up to over a 1/2ohm total which generates a lot of heat. The reason that the subs are getting so hot is that they are working really hard to try to pull more power from the amp which is trying to remain stable and is becoming hot which will decrease its performance causing the subs to work even harder. It becomes a very bad cycle that keeps compounding on itself. For future reference, regardless of the manufacturer, I recommend calling the respective technical department for clarification on there printed specifications. There could be changes or updates that the dealers are not aware of at the time of purchase."
i didnt try wiring the subs at 2 ohms but i tossed on a 10" kenwood sub to hte amp and it works fine,so maybe what audiobahn told me is true??if so i might gotta sell these bad boys and get something smaller,and the subs arent wired at 1 ohm the volt meter says 3.7ohms

Well email Audiobahn back and tell them they are full of SHIT! All voice coil ratings are noimal, always have and always will be. To me nomial can be + or - .25-.5 ohm so again they are full of it. Again my opinion of Audiobahn is lowered by things I read. Ditch that amps and get a real amp, or ditch the subs for something else.
