My speakers sound like mud...

The stock speakers in my 02 Sierra crapped out so I bought Alpine SPR-17S speakers to replace them. The new speakers sound like crap but I still have the factory HU in my truck. I've read that replacing the HU should improve the sound of the speakers, any truth to this? I planned on doing this anyway, but down the road once I saved some $$$. I also read that hooking the speakers up to an amp would further improve sound, again, any truth to that? Thanks.

I think both the HU and an amp would eventually be needed, I would go with the amp first and then the HU

Go with the amp. If you keep good tabs on them you can find a good alpine amp on e-bay for $100-$150 that will be good enough for what you have. I have two vehicles with all alpine setups and most of the R series speakers need amps to sound anything close to the way they are meant to sound.
