[QUOTE="RSDXzec, post: 8044535, member: 638347"] The idea was to run it on a separate amp so differing impedance wouldn't be an issue, my concern was causing cancellation at certain frequencies if the subs responded differently as one would be in a different box to the others No, they will be covering the same frequencies and were going to be run on a different amp if the box was going to be another size, but at this point I believe I'm just going to go with the same size box/tuning freq to make sure all the subs respond the same. Then later on if I want I can run them all on the same amp. old *** hatchback, 3 12" subs rated at 350WRMS, amp rated at 1500WRMS so it's capable of taking on 4 of them. I'm not going over that power because the cars electrical is being stretched to it's limits, recently had the alternator rebuilt/upgraded and I'm buying an AGM battery soon. is that with the 4th sub in a different size chamber? or all the same? Cheers. [/QUOTE]
