My SA-HE70 has a problem with it's sub out. I have to pull the phono lead to one side on the back of the amp to stop it buzzing, and sometimes it just starts buzzing for no reason.
I don't think its the sub (which is a amplified), so I was wondering if anyone knew if it is a problem that can be fixed, or should if I should just get a new one.
The other problem is that you can turn the thing off by just tapping the case. Seriously not right!!

The SA-HT700 is the main unit for the SC-HT700 DVD Home Theater system. For this system, the sub-woofer (SA-WA340) has the AC power connection. The sub-woofer is connected to the main unit by a "System cable". The power cord and system cable are shown in the manual. You'll need the sub-woofer if you don't have one. Amazon has a used sub-woofer listed here: https://www.amazon.com/Panasonic-SB-WA340-Powered-Subwoofer-SA-HT700/dp/B076HB8HQP . However, I don't know the third-party vendor.

if none of the above could you please give me more info please.
Most subwoofer have a left and right phono/RCA sockets. The amp should have a sub out phono/RCA plug. The sub should have come with a phono/RCA lead that will connect these - one plug to two plugs.
Apart from the mains plug that's all there is really. You may have to switch the sub socket on the amp on.
Not knowing anything about your 'external' amp or how you want it to function the only thing you could do is feed it the analog stereo output of the SA-HE70 from one of its OUTs (Tape or VCR). It won't be volumed-controlled by the SA-HE70.
Sounds like the output on the TV is a phono socket or a jack and the inputs on the sub woofer take banana plugs. You need (or should make up) a lead with a phono or jack plug one and and two banana plugs the other end. (phono plug/socket has two connections and banana plugs just one)
If you can provide the model numbers of the two bits of equipment I can check this for you.
I had a similar problem. In order not to mess up the jacks from the speakers I bought some mini jack to stereo rca adapters. I cut off the rca jacks from the end and then is just a matter of figuring out witch ones are left and right channels. For the subwoofer it's best to figure out which one is the sub channel so you don't have to cut off the rca plug from that one.
