I bought my cobalt a week ago and I'm in the middle of tracking down a wiring issue most likely a break in the left front speaker wire or some interference, I'm planning to cut into the output on the amp connector and run new wire and test a speaker and see if that solves my problem, ive searched and looked over the wiring for the amp but I'm not 100% sure if I have the correct wires or if I'm looking at the right connector on the amp, if someone has pictures of the connector with the wires labeled or can help with which wires to cut that would be great, thanks guys.

there should be 2 sets of wires one for the tweet one for the woofer. both would be colored tan/gray

Yea I found those Wires but the door speaker had a grey/BLk stripe and Tan and the tweeter had a solid Grey and tan wire so that's what's throwing me off

hmm odd but thats cool. on mine im 88% sure they were the same color but its nice they put a black stripe to show woofer vs tweeter

so i should cut the grey and tan wires on the smaller 16 pin connector and run them to a test speaker, and i noticed the pioneer speakers are all 2ohm would 4 ohm speakers work if i were to replace them all with new 4 ohm and what would it do to the sound? thanks for all the help Emperor.

it would give half power to the speakers so ur overall volume would go down

alright thanks, so you think the next step is to cut the grey and tan and test a speakers off of there?

EmperorJJ1

mmm well i would check continuity to ground on the wires first that will give u an idea if theres cut wires. if nothing turns up then test the speakers at the amp / before the amp and see if its the amp

alright thanks, im gonna test the wires that are already ran inside the door and go from there.
the door wires are not broken anywhere
so i ran some wire off of the grey and tan wires off the amp connector to the stock speaker and just got very low static when i turned music on,then i cut the wires from the head unit to the amp and tested the speaker and got nothing at all on 2 different speakers i tried, im lost at this point.
and i finally found a link to the correct pinout for the 07 pioneer system (https://www.cobaltss.net/forums/elec...-system-35819/)

and i was just re reading the headunit pin out over and saw that the wires i tested the speaker on were "low level audio signal" wires but shouldnt there still be some sound coming out of the speakers?

correct you would need to crank the hell out of the HU to see fi ur getting sound. so if u had the amp unplugged so only that one speaker was "playing" that would be preferable

Tyler Z28

ok ill give that a try and report back

....I just tried it and it WORKED it was very very very low in sound but it was still there, so now knowing all that we do what does this mean, that the amp might be the problem? because when i cut the amp out puts for the left front speaker all my other speakers worked but when i hooked up the test speaker i just got the static?

EmperorJJ1

iTrader: (5)

def sounds like the amp is fucked but knowing that not sure the best approach to fix. id say either go aftermarket amp and all speakers/sub but at that point might as well replace the HU too for good measure. or just disconnect the left front for now

Tyler Z28

Yea I have the left front out of the car, what if I upgraded to better 2ohm speakers in the 6x9's and the right front to compensate for the missing speaker

EmperorJJ1

iTrader: (5)

maybe but if the speaker isnt blown and its the amp then it doesnt make a difference.

did you ever unplug the stock tweeter?

Tyler Z28

iTrader: (2)

yea the tweeter has been unplugged and the reason i brought up replacing the speaker was to get a little more sound out of the 3 working speakers that i have in the cabin so i dont notice the missing door speaker as much.

EmperorJJ1

iTrader: (5)

OH you mean replace the speakers other then right front. Ya you could do that

Tyler Z28

iTrader: (2)

And I should go with 2 ohm replacements or what coypu suggest?

EmperorJJ1

iTrader: (5)

right if ur using the stock amp then 2 ohm is a must

alright ill take a look at some, thanks for all the help.
