I'm not sure if this is the right spot, but...
I've got a Panasonic XR55 reciever and a Carver PM900 pro audio amp for my sub. The problem is, is that the XR55 doesn't give out a hot enough signal to properly drive the PM900. It doesn't get as loud as I really think it should. My 180WRMS 8" computer sub should't be able to keep up with an efficient 12" sub (IDMAX) getting 900WRMS
Would this do the trick?

how would I go about setting all the levels once I connected something like that? |

Hi spots25,| quote: | | Would this do the trick? |
No.
1. mic level is way too low for the rcvr output. (module overloads)
2. probably will not have a high enough level.
3. 741 op amp. (noisy, slew rate okay for sub)
The Carver will destroy your sub if you ever get it to deliver it's full rated power to your sub. The Carver does require a solid AC connection. Your other devices will not be happy about this. Trust me. The Carver is a great amplifier for this use, your single AC circuit is not up to the task if it's a regular house circuit.
The efficiencies of the two speakers will have much to say about the sound pressure level. Your ears are not sensitive enough to hear a large difference. It's not a linear relationship (power vs SPL). To hear 2X the volume, you need around 10X the acoustic energy. That's a cruel fact of life.

| so, what would anyone recommend for boosting the signal a little? |

Hi spots25,
You could try using the SSM 2142 balanced out IC. It boosts the signal +6 dB. It also converts the signal into a balanced from a single ended. Anything along that line should help you out.
