Why do you think you couldn't do it yourself?

#1. Do you have 2 speakers running from one amp?

2#. Is this setup for a PA system\DJ or audio reproduction system?

3#. What type of speakers are you using? IS this a stereo setup you are looking to make?

I think this thread may belong in the car audio section...but anyway, if you are running these speakers off of the head unit, I doubt if it can drive them. You should use a seperate low pass filter + amp. There is more than one way to wire them, but as for starters, you want to choose an amp that is not too powerful. For good sounding results and longer life, don't drive the speakers much more than 60% - maybe 70%(depends on brand or quality) of rated power because the diaphragm movement will no longer be linear. Also you can wear out the reflex & spider. I suggest buying an amp with as much or slightly less max output than what the speakers are rated and turn the amp gain to about 60% power. This way the amp is not working super hard(less THD) and the speakers will last longer.

It's WAY cheaper to buy a car amp than build one. Even if the labor is cheap.
