    Run your sub amp off of the cap. Sure you can run both amps off of 1 cap, but it's not necessary. The sub amp requires the huge bursts of power, not the 4 channel amp. if the 4 channel amp is causing issues then you have a much deeper power problem. like time for a new alternator. The 4 channel amp shouldn't be cutting in and out with the bass. This problem really does ultimately point to the need for a new alternator. If you already have the cap, then hook it up to the sub amp and see if it improves your problem.

    if you have an alternator that is truly capable of producing 105 amperes then you should be alright. It might be worth having tested for output and then having it rewound for higher output if needed. this is much cheaper than buying a new alternator.

    To discuss the possibilities of your problem even further...what size of power and ground wires are you using? Where do you keep your gains set at? Two amps blasting away at full power will draw on the alternator pretty hard. Also, if your power wires are too small then the juice will have a harder time traveling from the alternator/battery to your amps, also making the alternator work hard.
