what does this mean?? RMS power 13.8VDC

i have this amp running two 12" subs bridged with the pos and neg wired together on each sub, but when i hook the amp up to one of the subs bridged it don't sound that good but sounds great on both of them! whats the deal with that? if each sub had it's own amp would it sound better?

RMS power 13.8VDC
Power 4 Ohms............................... 120W 2
Power 2 Ohms............................... 200W 2
Bridged power 4 Ohms ................. 360W 1
Minimum speaker impedance.............. 2 Ohms
THD distortion....................................... 0.08%
IMD distortion........................................ 0.08%
Frequency response............................. 20 Hz to 20 KHz
Input sensitivity..................................... 200mV to 6V
Input impedance ................................... 15K
Signal-to-noise ratio............................. 90dB
Channel separation............................... 50dB

 

means your amp is rated at that power when it is getting 13.8 volts. if your amp is only getting 12.5 volts, it SHOULD actually be putting out less rms thanadvertised. i said SHOULD for a reason.........everyone seems to rate their amps to suit their advertising needs until recently when the major brands signed on with the cea guidelines.

 

how do i check how many volts it's really getting?? basically i want to do this:
4 ohm bridged output on a 2 channel amp, with two single voice coil subs... looking to get the 360watts


edit: right now my wiring is like this, but it's bridged!

take a voltmeter and turn everything on and check the voltage

You won't hear a difference between 12.8 and 13.8 voltage to the amp. The power loss is very minimal especially on that amp. Why not run each sub at 2 ohms if you can, I'm not sure what VC config they are though. But at 2 ohms un bridged you get more power than 4 ohms bridged.

 

how is that wired?

 

What VC configs are the subs, then I can tell you.

 

i got the insignia set up... two 300 max 12" svc 8 ohm & 360w two channel amp

Ok you got them wired right, if the postives are put together. You may be bridging it wrong on the amp. In order to bridge, only use the outside outputs on the amp.

 

yeah... on the amp it tells you how to bridge it, soit wired good enough i guess!

edit: i think i'm going to sell all of it!
