I'll be running them stereo with the front right speaker positive and negative hooked to the amp channel 1 positive and negative. The front left speaker positive and negative to the amp channel 2 positive and negative.<br /><br />My question deals with the rear. The manual for my amp says at a 4 ohm's mono I can provide 400 watts x 1 to the rear channel.<br /><br />Since I'm running one sub with the rear channels I would need a single sub that is 4ohms and then bridge the rear two channels to the sub.<br /><br />This would give me a 4 ohm mono setup for the rear channels right?<br /><br />If it's not right, could you explain how to wire the rear channels of my amp to a single sub to the manual specifications of 4 ohm mono load. Also I havent purchased the sub yet but I have the amp so buying a 2ohm sub is possible if needed.<br /><br />Thanks<br /><br /><br /> <img border="0" alt="[patriot]" title="" src="graemlins/patriot.gif" /><br /> <br /> <small>[ May 18, 2012, 12:42 AM: Message edited by: 90FoX ]</small> <br /> </font> </td></tr> <tr bgcolor="#f7f7f7"> <td valign="top" width="18%"> <font size="2" face="Verdana, Arial"> <b>90FoX</b> <br /><small>Member # 1974</small> </font></td> <td width="82%"> <font size="1" face="Verdana, Arial"> <img src="https://californiafords.com/ubb/posticon.gif" border="0" alt=" - " /> posted <script language="JavaScript1.3" type="text/javascript"> document.writeln(timestamp(new Date(2012,4,18,0,50,0), dfrm, tfrm, 0, 0, 0, 0)); </script><hr /> </font> <font size="2" face="Verdana, Arial"> Here is a screen shot of the manual if this helps explain it.

Using only one 4 ohm sub makes it easier. If you were using 2, you would need to get a pair of 2 or 8 ohm subs, and wire them either in series or parallel. I did audio for years... PM me if you have more questions.<br /> <br /> <small>[ May 21, 2012, 01:07 PM: Message edited by: straightliner1 ]</small> <br /> </font> </td></tr> </table></td></tr></table> <br /> <br />
