I have an Mtx Thunder6500D pushing 2 12" JL Audio W3...my amp is mounted under my drivers seat, and after 30 minutes of music, my **** overheats and cuts out for a minute, WHAT CAN I DO!!! i gotta 94 Maxima, mounting in the trunk is not an option, it has to stay in its current location>

what ohm load are you giving the amp? My 1000d wasn't stable in anything under 2 ohms

ThumpinMaxima

im really not sure....

what are the subs rated at? Single or dual coil, and how many ohms per coil? Look in the manual

ThumpinMaxima

here is my sub, i got 2 of http://www.jlaudio.com/subwoofers/12w3.html

which one of these do you have:

Available Configurations: Dual 2 ohm, Dual 4 ohm or Dual 6 ohm

ThumpinMaxima

AHH i dont kno, how can i tell, i ddint install it.....

it might say in your documentation, or probably on the back of the sub. Try to find someone you know, that knows about audio, because I think it will be tough for you to figure out how to wire it properly(if it isn't), even if I explain it to you.

my amp is just gettin very hot, so hot i cant even touch it under my seat....

ThumpinMaxima

it was installed by circuit city

That amp is designed to only run in 2ohms(lowest) If you give it a lower load, it will over heat and shutdown, or blow(like mine did). Did this happen from the first time you installed the system, or did you develope it later? If I were you, I would not use it untill you figure out if it's wired correctly.

ThumpinMaxima

alright, well....ill go get the paper work circuit city gave me

ThumpinMaxima

it says NO where on here how its wired

ThumpinMaxima

for some reason, i think its a 4 ohm load....

If it is, then I can't help you much. These amps are supposed to run very cool. Check the ground wire make sure it's snug. Wait for other people to respond.

my mtx amp gets hot in my trunk, and i live in fl. but a quick fix could be to put on the ac vents on the floor to cool the amp. that shuld help.

eh that could work..but amps are designed to run without any extra circulation unless in extreme cases...under a seat..mabey. But...Im guessing thats a 2 channel amp. 2Ohm stable in each chanel?. If so..Hopefully you have dual 4 or dual 6 ohm subs..each sub ran at 2 or 3 ohms to each chanel. If they bridged the amp...they would need to wire each sub at 8 or 12 ohms..put them togetehr which would mean both speakers wired together would be 4 / 6 ohms then bridged the amp would see 2/3 ohms. If they did anyting other than that..im sure your amp is overheating due to too low of resistance.

aaaaaaaaaaaahhhhhhhhhhhhhhhh......so much for sounding smart at 3 am...

ThumpinMaxima

i keep the AC runnin at full blast...should i try putting fans under my seat?

just put the floor vents on, if that doesnt work, talk to circuit city.

You need to either pull the subs yourself or get circuit city to do it. You should have the dual 2 ohm subs, wired in series. Then parallel the two subs to the amp for a 2 ohm load. And still keep the AC vent switched to either just the floor or both floor and dash vents. That will keep cool air flowing across the amp. And check the ground wire like was said above.

ThumpinMaxima

could u walk me through wat i need to check for in the wiring, of the sub and the amp...ill also check the ground tonite

jmax

Go to jlaudio.com. Go to the tutorials page, and look for the dual voice coil wiring tutorial. That's going to be easier and possibly more complete than me rushing through the proper wiring for a 2 ohm load at the amp.

thanks for all your help guys, if this doesnt work ill repost...any other ideas. feel free to leave...once again, the org saves me
