1. An apparatus for detonating an explosive body associated with a downhole tool, comprising: a plurality of firing heads, each firing head including an initiating explosive body generating a high-order input when detonated; anda funnel configured to detonate the explosive body associated with the downhole tool by using a single high-order output, the single high-order output being formed of at least one of the generated high-order inputs, the funnel having a body that includes: a plurality of input openings, each input opening positioned next to the associated initiating explosive body to receive the generated high-order input, each associated initiating explosive body being completely external to the funnel,a single output opening being oriented to direct the single high-order output to the explosive body associated with the downhole tool; anda flow path connecting the plurality of input openings with the single output opening. 2. The apparatus of claim 1, wherein the flow path includes: a plurality of inlet passages, each inlet passage in communication with one of the input openings,a single outlet passage in communication with the single output opening, anda juncture connecting the plurality of inlet passages with the single outlet passage, the juncture being configured to consolidate the high-order input of each initiating explosive body to form the single high-order output. 3. The apparatus of claim 1, further comprising: an initiator positioned in the funnel and adjacent to the single output opening, the initiator detonating the explosive body associated with the downhole tool using a high-order detonation, the activator being detonated by the high-order output exiting the single output opening. 4. An apparatus for detonating an explosive body associated with a downhole tool, comprising: a plurality of side-by-side firing heads, each firing head including an initiating explosive body generating a high-order input when detonated;a funnel having a body that includes: a plurality of input openings, each input opening being positioned next to an associated initiating explosive body that is completely external the funnel, each input opening being positioned to receive the generated high-order input, wherein each input opening is in communication with an associated passage,a juncture connecting the associated passages of the plurality of input openings,a single output passage having a first end connected to the juncture and a second end, anda single output opening formed at the second end of the single output passage, wherein the plurality of input openings, the juncture, and the single output passage cooperate to form a single high-order output from of at least one of the generated high-order inputs, the second end oriented to direct the single high-order output to the explosive body. 5. The apparatus of claim 4, wherein the passages associated with the plurality of input openings are non-parallel to one another for a majority of a length of each associated passage. 6. The apparatus of claim 5, wherein the single outlet passage has a diameter that is at least twenty percent larger in size than the diameter of the passages associated with the plurality of input openings. 7. The apparatus of claim 4, further comprising an enclosure having a sealed interior in which the plurality of firing heads and the funnel are disposed. 8. The apparatus of claim 7, wherein the enclosure is configured to isolate the high-order output of the initiating explosive bodies from one another before entering the funnel. 9. The apparatus of claim 4, where the plurality of side-by-side firing heads are configured to be simultaneously activated by the same firing signal. 10. The apparatus of claim 4, where the downhole tool further comprises a detonator cord detonated by the explosive body. 11. The apparatus of claim 4, further comprising an initiator positioned adjacent to the single output opening, the initiator including a high-order explosive that generates a high-order output when detonated by the single high-order output, the high-order output of the high-order explosive being configured to detonate the explosive body. 12. The apparatus of claim 4, wherein the passages associated with the plurality of input openings are non-parallel to one another for a majority of a length of each associated passage, wherein the plurality of side-by-side firing heads are configured to be simultaneously activated by a same firing signal, and further comprising an enclosure having a sealed interior in which the plurality of firing heads and funnel are disposed, the enclosure being configured to isolate the high-order input of the initiating explosive bodies from one another before the high-order outputs enter the funnel. 13. An apparatus for detonating a downhole tool, comprising: an explosive body configured to detonate the downhole tool;a plurality of firing heads, each firing head including an initiating explosive body generating a high-order input when detonated; anda funnel separating the explosive body and the plurality of firing heads, the funnel being configured to detonate the explosive body associated with the downhole tool by using a single high-order output, the single high-order output being formed of at least one of the generated high-order inputs, the funnel having a body that includes: a plurality of input openings, each input opening positioned next to the associated initiating explosive body to receive the generated high-order inputa single output opening from which the single high-order output exits, anda flow path connecting the plurality of input openings with the single output opening.
