Help me decide on the right speakers and amps

[johnnyt5646]

I am looking to upgrade my system on my bike. i currently have a HD street glide with Hertz hcx165 in the front and hcx690 in the rear. each speaker has 100 watts going to it from a sound stream 100x4 amp.

I am looking to get a separate tweeters and midrange/midbass. i was thinking 6 1/2 with tweets up front and 8" with tweets in back.

i was looking at speakers from these companies:

Digital Design VO

Crescendo pwx

selenium 8MB4P and 6W4P

prv audio 8MR500-NDY-4 and 6MR500-NDY-4

how do these compare to the hertz spl show line. a lot of guys are using the spl's.

any other suggestions.

how about amps and tweeters

I would like it loud and clear with a little bass.

Thanks for your help
