I checked your SIG. They seem to be for a different car
Well after some more time I got it off. Got the new speakers in and replaced everything back. They sound much better. I went with some Pioneer's that I had bought for another car a bit back and they didnt fit (Volvo's special).
Now I just need to make some time to replace those front ones. This stock stereo is just weaksauce.
look a little deaper in the link I gave you ingore the 2001 thing..

Yea but not like this.
4 speakers at 25watts that are all in crap locations.
Ive got two other cars with stock radios and speakers and they blow these out of the water.
Try an extended cab 94 f150.... the stock p5 radio rocks in comparison.
