I need some advice

[cidme]

Im trying to design a system for my motorcycle but I dont know what amp would best suite my needs. Its needs to be small and loud enough to hear at 70mph on the highway with wind blowing. I also plan to use my Ipod as the primary listening device. here are two links to some speakers I have been looking at.

Didn't V-bro put an amp on his motorcycle? *thinks*

I can't see any ohm-ratings at a quick glance, but that power range 35-45W suggests Amp4 to me. It's *quite* compact, though not a breeze to make.

That said, amp6 is still a good choice. If space is a premium, try amp3 (and the mini versions).

sorry I should have said they were 4 ohm, space ie premium but power and quality of sound may win over.
