Need some help with audio issues

[kingsleysurf]

ok i thought i understood this, but i guess i dont... i need a 2 ohm stable amp to bush my 1 sub at dual 4ohms or i could have a 1ohm stable amp pushing both subs at dual 4ohms

heres my question, i was looking at the a2300hct audiobahn amp it says it can handle

4 Ohm Stereo: 300 X 2 Watts
2 Ohm Stereo: 600 X 2 Watts
1 Ohm Stereo: 1200 X 2 Watts
4 Ohm Mono: 600 X 1 Watts
2 Ohm Mono: 1200 X 1 Watts
1 Ohm Mono: 2400 X 1 Watts

so this mean if i run both channels at 2 ohms then both speakers will only get 600 watts each correct? BUT if i bridge them to mono and run both subbs off the one channel and it is a 1 ohm I will have 1200 watts running to each sub? or 2400? 1200 right?

Also more than likely i will get that amp, but would getting 2 jbl bp1200.1's and hooking 1 amp to 1 sub then the other amp to the other sub do the same thing?
price is only different by about 20 to 40 dollars...

and yes i know audiobahn is better than jbl, just wondering

I am confused... Do you have one sub with dual 4 ohm voice coils or 2 subs with dual 4 ohm voice coils?

Your reasoning is right there... Run the amp in 2 ohm stereo mode and you will get 600 watts to each sub. Run the amp in 1 ohm mono mode and you will get 1200 watts to each sub.

Buying 2 JBL amps would also do what you are describing, assuming that they each have an output equal to half of the Audiobahn amp at the given load.

sorry i have two subs with dual 4 ohm voice coils

Then you could do one of these three:

1) Wire the voice coils in parallel and wire the subs in parallel and run the A2300HCT in 1 ohm mono mode.

2) Wire the voice coils in parallel and wire each sub to its own channel on the A2300HCT and run it in 2 ohm stereo mode.

3) Buy two JBLs, wire the voice coils in parallel, and wire each sub to a JBL running in 2 ohm mono mode.

Personally I would do number 1, but that is just me. (I have 1 A2200HCQ powering 3 Audiobahn ALUM12Qs in 1 ohm mono mode)

ok so let me see if i get this right, using another spec on another amp just to be sure

the amp is mono block amp and 1 ohm mono stable

300 watts x 1 @ 4 ohms mono
600 watts x 1 @ 2 ohms mono
1200 watts x 1 @ 1 ohm mono

if i bridge the speakers at 4 ohm dual voice coil and to the amp it is 1 ohm mono, only 600 watts will be going to each speaker correct?

not 1200 to each
