i replaced my front speakers with polk audio comps well they were a pain in the a** to install but we did it but i also replaced my back speakers and they way over power the fronts u cant even hear them on at all when fader is set at 0. well i set the fader to just the front speakers and they are working and they sound good but u cant hear them, their just not loud. why i plan on checking the polarity possibly this weekend but untill then i need some ideas. they worked fine when they were in our grand prix the sound was balenced unlike the bonneville. any ideas?

I saw in your sig. you setup, I dont know much about the speakers that you have but If you have a speaker that has a higher RMS and you are under powering them (HU power) then they will be quieter then cheeper speakers.

Yea, I noticed that too with previous vehicles. Maybe just get a small amp and cables for under 100$.

they are operating at a lower ohm than the stockers. I think that the stockers are 8 ohm and the Polks are prolly 4 ohm

IF they had a lower impedence (less ohms) then they should be louder because there is less resistance in the line to the audio signal. I agree with getting an amp though, you really need at least a cheapie to get good output out of ur new speakers

the stock were 4 ohms and the polks are 4 ohm also

:?:

Good aftermarket speakers sometimes have lower sensitivity ratings. Im just guessing that the stock speakers are around 90 db. I put rockford components as my fronts and they have an 87 db sensitivity. Theyre almost half the loudness as the original, check the specs. With low sensitivity you need more power to get the same SPL ( loudness)
the only thing you can do is give them more power. I HAD to go with an amp to run my rockfords just so they arent drowned out. More power = better control of speaker which = better sound!
good luck!

Dang -now I have the same problem in my SSE. I put Infinity 6x9'* in the rear and Alpine 5.25" 2-ways in the front doors and they have alot of highs but no mids. And to add to that fact I still am running through the BOSE 2 ohm amp and using a 7-band EQ factory deck, so there is nothing but what sounds like 10" subs in the rear and some really sharp highs up front -definitely not gonna be bringing home trophies with this sound.
So I guess I'm gonna have to straight wire the front speakers (from radio directly to the speakers instead of through the BOSE amp) or get the 75x4 Soundstream amp that I just found for $70 at a local pawn shop.
Can't wait to get this fixed as well as a new MP3/WMA deck (still looking to see what I can get for around $250).
