Im hoping maybe someone on here knows something about automobile audio systems (amplifier and subwoofers). lately my car has been doing something weird to my system, when i accelerate, i lose almost all of my bass. then when i press my brakes, my bass comes back full force. can someone help me please?

For almost any set-top box, there isn't a sub-woofer output. Without that output (it would be labeled on the STB), you can't hook up a subwoofer directly to it.
HOWEVER, the model number you give isn't just a subwoofer: it's a whole sound system with a subwoofer attached to it. If you have the whole sound system, you just hook the STB's audio output to the amplifier's "Aux Input" (it might also be called "line input").
If your model doesn't have that (can't tell from the web), you'd have to buy an "AV Receiver" that has at least a 5.1 set of outputs. These start at maybe $150 new, $50 on eBay. MAKE SURE YOU BUY A RECEIVER WITH A "powered" SUBWOOFER OUTPUT!! You connect the receiver to the STB, and the subwoofer to the receiver.
If you looked at the manuals for either product you would NEVER find a recommendation to use one amplifier's speaker input to drive the LINE LEVEL (very small) input on another amplifier. Speaker outputs are for driving speakers or amplifiers designed to accept speaker-level input (like some self-powered subwoofers). In no case is the power of the originating amplifer BOOSTING the power of the driven one.
You should do some reading on how amplifiers work before you blow something up and come asking for advice on how to resolve it.
Sorry to said but Jamo SW410E is an active subwoofer. This means that is has his own amplifier for the speaker (that why you can see at the back panel of the sub the RCA connectors for Left and Right (line in level):
In the meantime your Panasonic SA-PM19 stereo system has none connector for audio out (except the one for the heaphones). So it's not possible to connect these 2 audio devices together.

Hello, Firs of all lets get agree on something..The subwoofer has three audio connections for "output " to :front,centre and rear speakers...these are not for "input"..Your powered SUB provides necessary signal for other spekers.. You can connect TV audio coaxial to SUB input with a RCA cable.....if your SUB does not have "RCA input " probably it should have "3,5mm Haedphone female Jack".. if this is the case you need to buy a cable ; one end 3,5mm MALE headphone jack and the other end 2xRCA stereo (or 1x RCA for mono or you may need "Y cable " ) to be connected to your TV... And you need to connect front,centre and rear speakers to your SUB as well... Take care and if it succeeds please Remember to rate/vote and give me 4 Thumbs Up for Helping out the Community :) Hope this helps!
Maybe you could name the subwoofer model so we know what it needs for input.
And we need to be careful with the indiscriminate use of the word 'power' in audio discussions. There's wall power and there's amplifier (audio) power.
In the case of subwoofers, some are self-powered (AC power cord plugged into the wall and an amplifier built-in; usually receives subwoofer-specific audio program via RCA cables from YOUR source); others are passive (just get audio power from YOUR amplifier.
The basic would be to wire the sub amp to your batteries with the trigger/remote wire powered by your car stereo/head unit. When your head unit is turned on it will in turn power up the sub amp. Of course the sub woofer need to be wired to the amp. For the signal/audio wiring, normally, the head unit has a stereo RCA female connectors at the rear intended to be connected to external amps through a pair of shielded/audio cable terminated both ends with RCA males. Some units have a special RCA specifically for subs. Most eternal amps also uses RCA for their inputs.
If the existing car audio system has already an external amp and your plan is to add on to this, the audio/signal from the head unit could be split to provide both for the existing and the new sub amp.
If the existing car audio does not have an external amp and their are no RCA connectors at the rear of the head unit, it is still possible to connect an external/add on amp by using an adapter that connects to the speaker wires of the head unit and converting it out to line level (through RCAs) appropriate for the input of the amp.
Hope this be of help/idea. Pls post back how things turned up or should you need additional information. it would also be nice if you can post brand/model of your head unit and intended sub amp.
