Question about Orion HCCA 275G4 Car Audio Amplifier
SOURCE: Orion 275g4 Hcca amp
this actually could be your amp...try turning the gain down slowly and you will hear the bumping either stop or become morelike music background thanmusic foregroud. i had this problem with an older amplifier and i fixed it by getting a larder power/ground wire size and decreasing the gain a little.

I honestly would go with 2 12 inch dual 2 ohm subs and wire them one per amp. That will give you a 1 ohm load to each amp and will give the HCCA's 2500 rms per sub... It will be stupid loud... 10s hit tighter than 12's usually and 12's tighter than 15's but u will get more air movement out of a 15 than the 12's and 10s... but... 2 10's require say a 4 cubic foot box to perform well... 2 12's require a 5 cubic foot box to perform well and 2 15's require about 7 to 10 cubic foot to perform to their fullest... no matter what if you put a sub in a box that's too small it will not perform or sound like what you want it to... go 2 12's and like a 5.50 cubic foot box or a 6 cubic foot box and you will love it...
