Im in the market for some new, cheap alpine speakers with tweeters and i came across these:
Alpine Electronics of Australia
now i ran my old speakers (stock) off a aftermarket HU and they sounded ok, but im guessing that i will need a amp to run these speakers rated at 75WRMS.
I confess i dont know what amp to get, i know you can bridge amp's channels to get more power but do tweeters use a separate channel to the speakers? Can someone point me in the right direction to finding the right amp?
Thanks in Advance

If you notice the box next to the speakers thats a crossover.
You can only use one channel of an amp with crossovers.
You could use a lower watt 4 channel and bridge two of the channels to each crossover to achieve more power.
To be honest if i were someone with the limited amount of knowledge that you have i would get a simple two channel at this point in time just to make things easier for you.
below are varius examples of nice inexpensive two channel amps that i would feel comfortable using. Just click on the links to view.

I would use any one of these to run the speakers above.
