    Oldsmobile Alero Speaker Help!!!

    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!

    I'd go on an alero forum and ask if someone has the diagram for it. The monsoon 6X9 subs are known to blow as they get old.

    Re: Oldsmobile Alero Speaker Help!!!

    What I post below is accurate to my Grand Am with monsoon. Should be identical to the Alero, I would guess, but double check. Easiest way of connecting new speakers will be to either pick the high (tweeter) wires or low (woofer) wires and only connect to one. Or just bypass the amp completely using the same wires below. I wouldn't suggest bypassing with a stock head unit though as the stock unit is practically a dead head and produces very little power on its own. You could always find the upgraded stock replacements for plug and play or find another pair of component 6x9s (I think Soundstream Tarantula has a set)

    If you are big into car audio, I would replace the whole monsoon system with something else. I know this is a bit more ambitous, but as the factory premium systems from GM start to age they start to really REALLY drop off, and your more than likely going to run into one problem after another one.
