Another Sub and amp combination , wiring doubt ?

audiophile · 2nd November 2006, 18:33

Suppose I have a 2 channel amp which on being bridged produces 300 RMS @ 4 Ohms, and have a 300 RMS Dual 4 Ohms sub, now the only ways I can wire the sub is either 2 Ohms in parallel or 8 Ohms in series.

If I wire it at 2 Ohms, the amp overheats,
So is it safer to wire at 8 Ohms ?
If yes why ? If no why ?

Experts

throw some light

audiophile - that is because in bridged mode the amplifier sees half the connected impedance. Please do a search before you post.

You will find some elaboration here.
