Multiple Speaker Wiring

the output of an amplifier is what it is.  Connecting more speakers to it doesn't make for more output, but the wattage is divided into the number of speakers.  "...2 ohms bridged 300 ea channel ..." is not correct.  A two channel amp, when bridged, is a connection to both channels.  Each channel alone cannot be bridged, but instead just connected to a load.  The load can be either one speaker or any number of speakers, as long as the total of the impedance load doesn't dip below the amplifier rating of 2 ohms/channel.

With four SVC 4 ohm woofers on each channel, the wiring would have to be made as shown in figure 2....resulting in a load of 4 ohms per channel.  Better results will be gotten by using less woofers on that amp.  I would go with no more than two good subs with it.

What kind of amp is it?  Because if you do this:

Your output may indeed go to zero when you blow your amp.  As indicated by stevdart in the above post, you can drop your impedence to 1 ohm per channel and most stereo amps cannot handle this.  It all depends on how you wire your loads and if the amp can handle it.

another prob if you do get the speakers wired to the right impedence so that the amp wont fry itself....for example you get 2ohms per channel or 4 ohms per channel ....You have to look at the power rating of your subs....You only have 600 watts total to use....You are talking about 8 subs....Unless you are running some really crappy subs that require low wattage you are going to be WAAYY underpowering your speakers.....This will result in massive distortion and possible sub damage...Underpower is just as bad as overpower....
