Extreme technical questoin re, built in amps

[secondtimelucky]

A little while back i was running an old pioneer active bass tube in the e30 (not sure of the model) which had a 4" dual coil sub in it, blew the sub up so i stripped the amp out of it, anyone any ideas on what sort of power output this would have??? It has a power consuption of 140w according to its heatsink....

well 140 watts is its peak output so around 60/70 watts rms.

is it any of the below?

Pioneer TS-WX22A - 8 inch sub - 150watts


or

Pioneer TS-WX11A - 8.30 x 5.03 sub - 150watts


or

Pioneer: TS-WX20LPA - 8 inch sub - 200watts

power consumption of 140w

Power consumption dude not peak output lol, and no it was much older than those, mine had a 4" cone

power consumption is used to state the maxium output also (seen manily on in-house amps) , look at the amp it might say the model number, and whats the fuse rating 20amps? as that will give an ruff idea on ouput which is worked out using the following: Amps x 13.8 =watts (this is at 100% efficiency). To get ture power you take watts / efficiency% = Real power

Pioneer Ts WX77A - 6.25" - 150watts


thats the smallest driver used i can find ,

Lol no worries then bud, il have a look and see if i can find more info about it from here
