I have two amps running to the battery. My radio fuse keeps blowing, so I was wondering if both the amps running to the battery is too much for the fuses and battery. Does a distribution block lessen the dependability on anything else in the car?

Blowing fuses is a sign that too much current is being drawn on a given circuit. Having said that, has anything else been connected to that circuit of late that may be overloading same?
The Radio fuse and wiring are designed from the factory to carry only so much current. On a typical OEM HU, we see 7.5 - 10A fuses. Some aftermarket HU's with more powerful amps, can demand more current than the original factory unit. So, if you have recently swapped out the factory HU and the new aftermarket HU draws more power, need a stronger circuit here. (sometimes a larger fuse and wire kit)
Also, does this fuse blow as soon as the HU is switched on or later, after playing it hard for a few minutes? Depending on your response, can give you more details on how to proceed. Are you using RCA lines to feed amps or high signal taps from the HU, to feed the amps thier respective signals?
Shorted speaker lines from the HU can/will blow fuses in the HU. Those should be capped off, sealed with insulating shrink tubing or nipped so that no wires are showing outside the insulation and well taped to prevent shorting. Comments?

PS In most cases, a D-block (for 2 amps) should not have any effect on the HU circuits.
