Re: wiring car amp up
The rem wire is for switched power from your head unit usually most after market stereos(head units) have an output for the rem wire.......if not use the power antenna wire from the back of the radio (usually blue or blue white) as for the input you need to use one or the other low or phono Hope this helps..Good Luck!

My advice would be to connect the front speakers and the sub woofer to the amplifier and run the remaining rear 2 speakers from the headunit. This way you dont stress the amplifier to run on two different loads at the same time and still maintane control over your system. Bridge your sub woofer on chanel 3&4 and do not forget to set the LPF for chanel 3&4. If your speakers are not components in the front set the HPF on chanel 1&2 to roughly 60 to 80 Htz.
You need 1 thick ground cable ( usually brown)
you need 1 thick power cable ( same thickness and wire as ground usually red )
you should have 1 rem wire ( thin blue )
RCAs, 2 for sub, extra 2 for 2 speakers.
The rest I have no idea what they are.
You need speaker cables to sub or amp.
Some products use different colouring. Maybe the 9 pin connector is for head deck to speakers.
remove all speaker connections to your amp. MAke sure the inputs are driving all 4 channels, and that the built in crossovers on the amp are all set to full range. Conect your full range speaker to each output channel one at a time and verify there is oputput on all 4 channels. If all is ok, then connect your rear speakers to the front(a) outputs of your 4 channel amp, and then use the second 2 channels (rear or B) bridged to drive the sub. Re-configure the crossovers for highpass for front (to drive your rear speakers) and lowpass for sub. This is the proper way to connect a 4 channel amp with a sup whle driving 2 full range speakers.
Your question appears under the product listing for the Dual XPA4100 but the in the text you say the amp is actually a Jensen, so it's not possible to provide specific connection information.
But most bridgeable amps can be connected to a single subwoofer and the other two channels used to drive a set of regular speakers. I'd connect the front speakers to channels 1 and 2 and wire the subwoofer to the bridge connections of channels 3 and 4. On the XPA4100, the bridge terminals are the first (negative) terminal on channel 4 and the last (positive) terminal on channel 3.
You have 3 power connection, +12v goes directly to your vechile's battery (make sure this is fused) REM connects to your head unit which tells the amp when to turn on and off (usually very thin wire, comnpared to the gnd and +12) Te gnd you already know where it goes.
Then connect your sub to + and - speaker out put. If you run this bridged it will increase your output, must be 2 channel to bridge to 1 channel or a 4 channel bridged to 2 channels.
Hope this helps.
