The unit puts out 240 watts max. Didn't get crazy with it. And it was very hard to cut the holes. I researched all the archives for weeks to get ideas for the speaker placement. Measured several times before I made the decision to cut the holes. Used heat shrink connectors on the splices and spent an eternity standing on my head tying up the wiring. Now that its all installed, it will be easy to upgrade stuff later.
