If I worked for Pioneer I'd say..."You'd better go out and buy 2 sets of Pioneer 6x8 (don't know nor care about model #'s for this post)...but, if you aren't interested in cranking the music up, you can hook up some bass blockers clicky to protect your factory speaks...however, I would reccomend a speaker replacement. you can find cheap ones all over the internent...
like here!
or here!

basically, it's all up to you and what you want it to do...just stay with a brand name that you've heard of...Pyramid=bad... laugh
