I know this site has calculaters but they don't help me when it come to DVC. I can do almost anything but ohms confuse the **** out of me. I have 2 15" High performance subs from parts express. Their 4 ohms per coil. So if I'm running them in parallel what are the ohms or how do I put that in the calculater. Any help would be app.

A speaker with two coils is put into the calculator as if it was two speakers, each at (in your case) 4-ohms. So, if you have 2 speakers, each with 2 coils, that is 4 coils total. If each coil is in parallel, that places 4 X 4-ohm coild in parallel for a net load on the amp of 1 ohm. If you connect the two coils on each speaker in series, this adds the resistances together of the two coils, so 4 + 4 = 8-ohms each. Put TWO 8-ohm loads in parallel for a net load on the amplifier of 4-ohms.

So your two best choices are to wire for either a 1-ohm or 4-ohms total load on your amp.

Oh by the way, what did you buy from Parts Express? I know they bought out the remaining stock of Kove subs, and they also handle the killer Dayton line...

Yea, those look like the Kove's. Big time SPL drivers. The Titanics are fantastic home theatre subs. I have one of the 12" versions.
