We are trying to connect a Thump THA-1000 audio amplifier in between the rear speakers and the stereo output on my sons 2000 chevy blazer. When we just touch the center conductor of the RCA plug to the jack we get audio but when we press it in further and the outside of the plug touches the outside of the jack, we loose all audio, even the audio going to the front speakers which we haven't touched.
Do you think we have an impedance problem or could it be something else?
Are Thump amplifiers still manufactured? If so, do you know of a website for the manufacturers?

the amp is going into protect mode due to something wrong in the amp or some thing in the wiring to it ooh yea if you are getting 18v power to the amp that is way to high it should not be higher then 15v if the amp is in protect mode it will not play at all.
yes, it is a bridgable amplifier, if that is what you are talking about. Look at the speaker output terminal and it should have markings on it for stereo output and it will have a line between the 2 terminals to use for bridging it. When you bridge an amplifier it is mono. There may also be a switch on the amp for stereo or bridged. Put that switch in the bridged mode. Connect one speaker to the speaker output and you have your bridged mono amplifier. If you plan on using 2 woofers, it is better and safer to use it in stereo mode with one speaker on each channel.
you mean a series connection, I'm assuming that you are connecting two speakers to one channnel (the right or left ) of the stereo. you take the positive and the negative leads and you put one on one speaker and the ohter on ther other speaker, positive (+) to positive (+) and negative (-) to negative(-). then you simply connect the 2 leftover connection of the speakers together with a wire. Be carefull though becaus if you do it wrong, it could short out your stereo or it will sound really bad...
If you are using a GM-7200 amp, it should sound great. Both the amp and the subs are rated at 800 watts so be careful not to overload the bass by turning them on full power. It is good practice to have a slightly lower watt amp than the subwoofers. If you can power your rear speakers from the amp, that would take away some power to prevent the subs from overloading. Overall, you should get a nice THUMP!!
