Re: what amp to use
Recommended maximum for the sub boxes is 1600/800
here is the link to the manual if you need it;
If you really wanted to get the maximum from your subs then a zx750, or possibly a zx1000 would be the ideal choice. Either amp you suggested will work, but you will have more fun with a 750 which should do fine.
Hope this helps :)

I am going to assume the 2 speakers in the sub are each 4 ohm loads, and are wired together in parallel, creating a 2 ohm load. And your amp pushes 800W at a 2 ohm load. And actually goes down to 1 ohm/1100W. Anyway...
Seems you want to lessen the wattage output of the amp by making a 4 ohm load. To do that, you need to wire the both 2 ohm speakers in SERIES. In general wiring principles, to wire in SERIES, take the POS terminal from the amp and wire to the POS terminal of first speaker. Take the NEG terminal from the amp and wire to the 2nd speakers' NEG terminal. Then place a "jumper" piece of speaker wire to connect 1st speakers' NEG terminal to 2nd speakers' POS terminal. Now you have a 4 ohm load, and will be pushing 450W from your amp.
Is your sub in a box? the power light is on your amp? try to connect a car speaker to the port you have the sub plugged into, if the speaker works its not your speaker terminal on your amp it's the sub. Check the wiring on the connectors of the back of the sub itself and the wire terminals inside the box (if sub in bass box)
Please let me know if this was any help and let me know if it solves your problem
What is the wattage of the sub?
What is the power output of the amp, bridged & not bridged?
If the bridged power output will NOT exceed the rated power of the sub then you should bridge it.
If it will exceed the rated power of the sub then don't. 8)
get a 2 channel with as much watts as you can affored. you wont blow them its better to have to many watts then not enought the subs work harrded with less watts i know that sounds crazy but trust me je
Has nothing to do with the sub's . This is an AMP problem. Best guess is you are running at too low of an impedance. Most likely (sight unseen) you are running a 2ch AMP @ 2 ohms bridged, or if the sub's Dual voice coil you are @ 1 ohm, and most amps frown on that.
Give me some specs..
Amp make, and model. And EXACT model # of the sub's. Give me this info, and I will tell you how to make it work.
not a bad amp by any stretch. they do carry a little more thd then some of your higher end amps but should do the job. you did not mention what type of other gear you are running with? your head unit needs seperate sub out rca, prefer 5 volt+ for cleaner stronger signal but any will work. you might want to purchase a good 1 farad cap run at least 4 ga if not bigger cable ( im running 00 gauge on 1500 watts to 4 momo 12's) make sure you have same size ground wire to an excellent ground source. not sure about your crossovers either, im running 2/3rd octave phoenix gold from the old days i swear by them. all that and a good box will help greatly. routing your wires the proper way and using higher end cables will help greatly also. happy beating, any more questions just ask and i do what i can to help.

try to check and clean the wiring as clean as possible to avoid messing up on your connection. Check the polarity of you subs to yuor amp if you have it connected on the outher way around it would not give you a good result. check the polarity this will solve your problem. Over powering your sub will fry it easily try to tune it a 10" sub wont give you a 15" performance..
you've spent alot of money on **** by the sounds of it!!. you should only ever run multiple subs the same brand, power and resistance you can just connect any old subs to a system you need to wire them depending on the load that the amp needs to see. first thing is to try the amp/s on a individual sub to check your amps still work once done check the subs 1 by 1.
for 1 the amp is no where close to strong enough for the subs and 2 if the amp is mounted on the box it is vibrating the electronics loose. you always want the amps rms power to be be about 25% more than the speakers rms rating, from the sound of it you are either undriving the amp (clipping) or running the amp at 1 ohm load which is making it burn up. if the amp gets hot (which class d amps should never ever do) then try running just 1 sub. if the problem goes away then you know the amp is not enough for the subs. try a hifonics amp you will be amazed at the quality and power difference. I sell all major brands cheaper than almost anywhere. let me know the exact model of the subs and i can recommend a better amp for you.
