HI there,

First time asker, so go gentle please;)

Is it possible to connect 1 sub woofer 200 watt, 2 200 watt speakers and 1 speaker 300watts to an 200watt amp minimum 8hms that can oncreased to 600watt with a bridge connection.

If this makes sense (cos this is the information I've been fed :eek: ) and you know the answer, can you please let me know as soon as possible please.

Cheers

K8 :cool:

The total Impedance(resistance)adds up. Amp Output Impedance important, Need.
4 8 ohm Speakers in Parallel = 2 Ohms.
4 8 ohm Speakers in Series = 32 ohms

You can do a series/parallel with 4 8 ohm speakers, so amp sees 8 ohms. With 4 8 ohm speakers.

True, but than each speaker get's only half of the available power, so radiates only 1/4 of the maximum volume.
.
But how to connect 1 sub woofer 200 watt and 2 200 watt speakers and 1 speaker 300 watts to an 200 watt amp minimum 8hms that can oncreased to 600watt with a bridge connection?
.
Only one sub woofer 200 Watt. Use that one for left channel.
Use the 300 Watt speaker with a filter as second woofer 300 Watt for right channel.
Both 200 Watt speaker can be split over left and right channels.

As the amplifier accepts only a minimum load of 8 Ohms, put in each channel a sub-woofer in series with a 200 speaker.

Amplifier :

---
Left ~ -----I SW1 I----- I SP1 I --I
Left 0 ----------------------------I
---
Right ~ ----I SW2 I ----- I SP2 I --I
Right 0 ---------------------------I
---

Whereby SW2 = speaker 300 Watt with bipolar 10 uF capacitor across the speaker connections (to make it sort of Sub Woofer).
