I have a 2001 oldsmobile Alero Gls (2 door) and i need some help with my speakers. I got this car from my dad for free and the rear speakers didn't work when i got it. I just assumed that they were blown out or something but sometimes a sound will come out kinda like a farting sound. So i decided to check the wiring in the trunk. There are 4 black and red wires then theres 4 different colored wires per speaker. I know two are the tweeters and two are the subs. Do the the black and do the pair of tweeter wires go to one set of black and red cords and the subs the other? or does 1 wire from the tweeter and 1 wire from the sub from go to one pair of black and red wire? I'm just confused havn't ever done anything with speakers. And oh yeah one more thing to add the car has a stock monsoon amp that came with the car and is part of the soundsystem. Right now i wired how i think they should be wired but the bass is just terrible but the lyrics of sons sound fine... I just really need help with which wires go together and whether or not the speakers are blown! thanks!
