You should be fine. You would be puttin 500 at each voice coil which should be perfect.

Yep, That'll work out real nice. Make sure you set the gains properly. Read a little bit and do it right.

Be extreemly carful when hooking 2 amps to one subs dual voice coils. even if they are the same make and model. One amp could be outputting slightly more voltage than the other and the dual voice coils could end up working against each other.

yeahh.... personally i would sell them both and get the 1000/1, , you should walk away with some cash in your pocket too, since i think 2 500's are worth more than 1 1000.

You can use the two 500's you just have to set the gains with a multimeter so they are spot on.

A 13w7 can handle the power, you wouldn't be giving it anymore than what is recommended. However, I would not hook up two amps to one sub. Even if you use a meter to set your gains, I just wouldn't mess with it. Even if you set the amp outputs the same, the two voice coils on the sub are not identicle in impedence. The factory specs show that they are, but if you put a meter to them they are never exact. I don't have a ton of experience to speak from, because I've never hooked two amps up to one sub, but I can tell you that to do so would be to contradict every article I've ever read on amp/sub wiring.

you will be fine using the two amps. set the gains with a dmm and you will be all set. if you do a search for wiring two different amps to each voice coil you will find a more detailed explanation. do not however bridge the amps together, the slightest difference will destroy the amps. one amp to each coil
