Okay so here is my situation. I replaced the 2 rear speakers in my Jeeps sound bar with Pioneer TS-A1675R and they sounded good on the stock head unit which i believe pumps out about 12 watts rms per channel. I then installed an Alpine Power pack KTP-445U.
Now the speakers sound very boomy (mainly the bass notes). The highs sound as expected just the bass sounds wierd and distorted, boomy/muddy, I am not sure how to describe it. I dont have the best seal so i ordered some rubber and am going to make a gasket so it is sealed properly in the sound bar.
I replaced one side of the front speakers with Pioneer TS-A1605C and have the same issue up front. The thing is up front, i left the stock speakers in before and after the install of the power pack and they sounded fine. For some reason when i switch to the pioneer speakers they dont sound good.
Any help would be appreciated. Thanks everyone.
