[QUOTE="Do_, post: 1544834, member: 556295"] Wait he just said his old sub was SVC 4 and his new sub is DVC 4? I bet you wired it up in series. If you do that then your new sub is effectively 8 ohm which will definately get you less power and sound. If that amp is 2 ohm stable you will want to paralell them. This will drop your effective resistance down to 2 ohms where you should get quite a bit more power than the original sub you had. Make sure your amp is 2 ohm stable first, then try this. Run a wire from the Amps + to one of the subs +, then a second wire from the amps + to the subs second +. So you should have two wires from amp to sub now. Then go from Sub - to Amp - on the first set of connects, and go Sub - to Amp - on the second set of connects. You should now have four wires. If you wire it this way the load your amp will see will be a 2 ohm load and it will put out more power. If you have it wired up in series + amp to + on sub - on Sub to + on Sub - on Sub to - on Amp then your resistance is jumped to 8 ohms where you would get quite a bit less power.
