Need Load/RMS help

[jbarnesiii88]

Hello.

I have been using a Dual XPE2700 Series 400w amp and 2x12"s SVC (bought as a set).

I recently acquired (1) @ 10" Memphis MClass 10" sub 4ohm DVC 600w (250-300RMS) and I have properly installed the sub and my own auto-venting system (for cooling purposes). I have had no problems so far. I know a lot about circuitry and electrical, but my fault is loads, and my concern is overheating my amp.

I have the 10" sub bridged to my amp (8ohm load on amp). The amp handles (150RMS x 1 Chan @ 4 ohms (bridged)). I have read that bridging a (4ohm 300 RMS DVC sub) at an 8ohm load actually only runs at 150-200 RMS. If this is the case, then I should not have any problems. I need someone to confirm this. If it is not the case, will my amp overheat due to a more powerful sub?

Thanks

shouldnt have no problems if the sub is wired correctly ,the amp will produce less power at 8 ohms tho

Yes, it is wired correctly. And I don't mind the power loss because I have a 1.6L Sentra that is a Rattlecage... I also have the amp set to a very low gain, but pretty high bass boost; hoping its not trying to push itself too hard. I listen to hardcore metal, so I don't want a lot of gain from the bass guitar anyways. Just the drums.
