07mazda3s Posted February 26, 2007 Report Share Posted February 26, 2007 I have one 12" sub right now in a ported box that I built. I'm thinking about getting two tens and sealing them about 1 ft^3 each. I have a 2 channel amp. Its 500wrms X 1 channel at 4 ohms but the sub I have now is wired at 8 ohms. It can do 250wrms X 2 @2 ohms. It is only 2 ohm stable for 2 subs. Will two tens sealed at 250wrms X 2 @ 2 ohms be as loud but tighter than one twelve ported at ?wrms X 1 @ 8 ohms?

sean 371 Posted February 26, 2007 Report Share Posted February 26, 2007 Well at 8 ohms youre only getting around 250 watts anyway. So yes it would be significantly louder. Twice the power and some added cone area. Actually, its a sony amp. So you'll get around 200 watts per sub. But either way I'd go with 2 subs at 2 ohms rather than 1 sub at 8.

Could I wire each of my voice coils to a channel on my amp to make 200wrms x 2 channels @ 4 ohms? Seems like it would work.

sean 371 Posted February 27, 2007 Report Share Posted February 27, 2007 I dunno about the specs on the sub or amp. But if the amp puts out 200w at 4 ohms x2, and the sub is dvc 4 ohm, then yes you can do that. It's not the preferred method, but it'll work fine. Should sound a hell of a lot better.

07mazda3s Posted February 27, 2007 Author Report Share Posted February 27, 2007 i have wired a sub up like this before and it worked fine. So the amp will never send a different signal to each of the channels pulling the voice coils in two different directions at once?

Chris Posted February 27, 2007 Report Share Posted February 27, 2007 No, not unless you're listening to some wierd techno of something that switches back a forth between chanels like the sometimes do using stereo but even then you shouldnt have a problem. 4 15" FI Q D2's in 12 cubes tuned to 32hz 1- T1000.1bd's 3 Maxx 29 deep cycles 4 runs of 1/0 gauge -Big 3 -Trunk sealed off from the cabin Custom 15.8 dual-volt switching MLA module All in a CAR.

07mazda3s Posted February 28, 2007 Author Report Share Posted February 28, 2007 I rewired it this way today. Its a little more clear and maybe a little louder. It def doesnt sound like an extra 150 watts. Overall it was worth the 15 minutes or so of work.
