[QUOTE="acreature, post: 2637000, member: 569125"] Well, I received my pair of Diamond Audio D310D4 (dual 4ohm voice coils) to replace my Infinity 1242. The Infinity was housed in a 2^ft slot vent tuned at 30hz and powered by an MTX 6500D. I built the box for the Diamonds sealed to Diamond Audio specs at .75^ft each. The MTX 6500D is rated as follows @ 12.5v: 250w x1 @ 4ohms 500w x1 @ 2ohms Now, I am feeding only 250w (wired 4ohms) to both Diamonds which are RMS rated at 400w [IMG]//content.invisioncic.com/y282845/emoticons/uhoh.gif.c07307dd22ee7e63e22fc8e9c614d1fd.gif[/IMG] I know I am starving the Subs for power, and have a simple question in hopes to avoid bumping up in Amp size. Would the following config not be a 2 ohm load on the Amp? Running each woofer's voice coils parallel, then each woofer in series.
