Just like the title says I'm looking for suggestions for one pair of speakers that would work well with what I currently have. I have the HawgWired sixpack now, and while it is a tremendous improvement over stock I still can't hear it that well over 60-65mph or so. It came with the RS400 amp (100 watts rms) so I was wondering if there is a pair of speakers that would be enough of an improvement over the HawgWired speakers to warrant the expense. I was thinking of getting lowers and adding speakers there as well but I'm slowly turning this thing into a bit of a hotrod and probably won't ever get the lowers. Just wondering if it's worth the added expense if I'm going to stay with only one pair of speakers. Also, still running stock head unit, might be willing to upgrade that too.
