ok, i have a dual voice coil sub 2+2 ohms. one ohm stable. i have the amp to match. mono 1 ohm stable. i have ran the amp bridged to the 1st voice coil, then jumped positve to positve, negitve to negitive on number 2 voice coil.... the amp goes into protect mode at about half volume.... it should be wired right for one ohm right?

help... anyone?

one view in an hour?

measure your sub with an ohm meter and see how much resistance is really there. 1 ohm is really low to run at and gets things hot rather quickly. Why dont you try 4 ohm?

widebody_balt_ss

well, i just bought everything to run at one ohm... just cause i never had before. I ran it at two ohms and it sounded good. but alot louder at one ohm.

Your losing me here. You have 1 2 ohm sub or 2 2 ohm subs?

cobi

try it at 4 ohm. I started out the same way running the lowest possible impedance I could but soon learned that it sounded much better the higher you went. 1 ohm is very easy to distort at, and can ruin things very fast. I ended up switching most of my stuff from 2 ohm to 4 ohm just because the loudness wasnt that much different and it sounded way better.

1 dual voice coil sub 2+2 ohms which means he can run it at 1 or 4 ohms

Yea I was just making sure. What Amp is it? I have a Kicker L7 2 ohm dual voice coil and i had a JBL amp that did the same thing. Needless to say it was the damn amp.

cobi

what amp was it? most of our amps (I work for Harman=JBL/Infinity) are only 2 ohm stable.

widebody_balt_ss

two voice coil. one sub two ohms apeice. (per v-c) the sub is one ohm stable. they are kenwood excelon brand.

first of all the sub doesnt care what ohm its at just worry about the amp. Now if you have a single sub and you wire it in parallel (pos to pos neg to neg) you'll get 1 ohm. If you have 2 subs you cant get one ohm with 2ohm DVC

widebody_balt_ss

yeah, only one sub.

What Amp are you using? If the highesr you turn your volume it starts going into protect mode, it sounds like your Amp can't handle it.

widebody_balt_ss

yeah... thats the thing, its an 1800 watt amp, 1200 rms 1 ohm stable.... it has me confused. it should be able to handle 5 volts from the head unit. everything in my car is kenwood excelon except my 6 1/2 components.

the input voltage doesnt matter... your amp isng going to go into protect because of 5v

the 2 things that id think were the problem is either a grounding issue or a ohm level issue. You stated that you have it wired to 1 ohm and your amp is 1 ohm stable it shouldnt be a problem if the amp is really 1 ohm stable. Check your grounds and make sure they are on a good chunk of metal that is clean and has no paint or anything.

also i didnt really read the first post because its confusing but now that i went over it again i just want to be sure you seeing a 1 ohm load. make sure your amp is wired like so

Fast Freddy

Great pic. That shows a 1 ohm load but if your bridging your amp its seeing a .5 ohm load.

if its a mono amp it cant be bridged... thats what threw me off about the first post

bridging is connecting 2 channels on a amp to a single load (to act as 1 channel)

widebody_balt_ss

BINGO. my amp is 2 channel but if you bridge it you can change it to mono from stereo. if i bridge it and hook it up like the pic shows and its .5 ohm. thats the problem. thank you,... I fryed the first sub,... oops. lol, oh well i have more. thanks for all the help guys.

try again croutching tiger hidden dragon... the ohm load doesnt change with the amp its completely dependant on the subs BUT if you have a 2 channel amp and bridge it the ohm its stable at doubles. So your 1ohm stable 2 channel amp would become a 2 ohm stable 1 channel amp

widebody_balt_ss

so dont bridge the amp run it stereo, and wire it like the diagram above?

i am just running this one to one voice coil now... its plent loud.

you can do that bridged to a single coil as long as it can handle it (if you subs rated at 800rms you shouldnt give more then 400 rms to a single coil)
