Audio Budget - What to get??

[mark_airey]

Ok, a lot of this is going over my head.

Ohms? i've seen a lot of subs, identicle RMS etc. but differ in 2/4 ohms? what is this??

Also bridging? What is this? splitting a sub input 2 ways to 2 different channels?

sorry, Ohms is the resistance reading of the magnet coil in the sub and the lower the figure the more strain is put on the amp but the better the output, you can get dual coil subs (so 2 separate magnets) which will be for example 2ohms a coil, this allows you to wire it up as either 2 ohms or 4 ohms depending on how its connected and what the amp is capable of

right bridging is when you use a stereo amp (so left and right in and outputs) and bridge the two outputs together using the + of one channel (for example left) and the - of the other (in this example right) this gives you a mono output but instead of having say 2 outputs and 100W you would get 1 output at 200w wiring it bridged (if the amp allows)

Not sure if that will have made things better or worse :?
