Very possible that you have a blown power supply in the amp. If you are running a mono amp then there is a very good chance that you have loaded your amp with too low of a speaker impedence and fried the power supply and maybe the output section of the audio area. Hope this helps.

First off, never, ever replace a blown fuse with a bigger one (especially one that is almost twice as big) unless it's an absolute emergency. Most of the time, the reason a fuse blows is because of a problem with the device (in this case, the amp). By installing a larger fuse, there's a very good chance the problem will become permanent (i.e. busted amp).
The amp could be going into an overcurrent mode when the bass hits and power cycling itself to try and reset the problem. If this is the case, take it to a local electronics repair shop and see what they can do.
It's also possible the input voltage to the amp is dropping too low during the bass hit, making the amp restart. Try putting a 1.0F or higher capacitor on the battery to buffer the power during the bass hits.

Keep in mind the input current to the amp is not continuous. Yes, the fuses on the 3501 are rated at 2x30A, but that means that at any one time, if the peak current goes above 60A, (theoretically) a fuse should blow. But in reality, the amp will draw much less current than that under normal operation. Even by adding the 300/4 to the mix, in my opinion, you will be ok.

SOURCE: Sub Wiring
Rockford-Fosgate claims their latest V-power 1500bd is stable to 1 ohm, and I would think that your Oldschool would also be. The 2 wiring options for 3 subs with 2 ohm dvc would give you a 1.34 ohm load and a 3 ohm load. The 1.34 ohm option would mean more watts to the subs, but the amp will run hotter. The diagrams look like this:
Using just 2 of the Kickers, you can wire 3 different ways, with final impedances of 0.5 ohms, 2 ohms, or 8 ohms. You do not want the 0.5 ohm load. It's bad for the amp. You don't want the 8 ohm load. It doesn't allow the amp to produce as much power. So that leaves only the 2 ohm, with coils in series and subs in parallel. It looks like this:
Hope this helps. If it does, please rate as "FixYa".
