RG5384,

To answer your myriad of questions, let's start with your amp. Is your amp rated at 150x2 RMS? RMS means constant power. A lot of amp makers out there rate their amps by the MAX power it can put out. This can be quite frustrating. An amp that's rated at 500W doesn't mean that it will play at 500 watts. What it means is that it is able to play up to 500 watts for the shortest amount of time, even as short as a nano-second. Another thing. When an amp says 500 watts max, that probably means 500 watts with distortion, and RMS would probably be cut down to half. Concentrate on the RMS number. That's what you'll be getting.


Second, you did not mention what type of subwoofer you have and its power handling. It's better to have one sub playing at 100 watts, than two subs playing at 75 watts each with distortion. The type of subwoofer you have will dictate on what type of box/enclosure you should use and how big the box should be. Check with your subwoofer's specs. All subs will require a certain amount of space, measured in cubic feet inches.

I wasn't sure on why you wanted to splice your rear speakers. Hope this helps.
