I have a 12" d4 type r 1000 rms and a alpine 1000 amp speaker sounds great but smells like something is burning, my amp never over heats or shuts down but the smell is still coming from the sub?

Cut your gain back on the amp. It sounds like they are set too high. Check your install instructions on how to set your gain. If you have a 4 or 5 volt output head unit your will not be at half way. Im running a JL Audio 500 /1 on a skar wwv10 dvc in a ported box. My gain is set about half way & its plenty loud.I have a Alpine 9887 headunit 5 volt output on my RCAsI can take a volt meter & set my speaker output at 45amps & my gain in perfect.

I have 8 alpine dvc type r 12s, should i port them

depends what kind of car they are going in and what kind of sound you are going for.
generally speaking ported boxes are louder, if you choose this i would recommend filling box with poly-fill.
non-ported boxes get deeper bass and hit much harder. no matter what set up you choose a good quality box that does not flex is EXTREMLY IMPORTANT. you will want the wood to be at least 3/4" thick and the correct cubic feet.

How to wire 2 alpine

If they are single voice coil, just hook one up to the amp (bridged) like normal and run a jumper wire from the positive of the sub to the positive of the second one, then do the same for the negative....This will give you a lower ohmage, thus better bass!!!
