keep blowing amp

so i keep blowing my amp and keep haveing to send it in to get fixed and i dont understand why? this is my set up if any one can help me or give me some ideas i would greatly apprecate it  i have a yellow top up front with the big 3 upgrade runing o gauge wire to a 200 amp fuse then all the way back to my stinger 30 fard cap  i grounded the cap to the chassis with 0 gauge then i ran 0 gauge to my power base 3000d amp witch i have ground with 0 gauge as well to the chassis i have 2   10s digital designs ran to 1.7 ohms on a dmm i dont get why i keep blowing it i was told to get a second battery but i dont know i am confused i have a pioneer avic n4 dvd head unit all good rcas if any one has any sugestions please let me know thanks chrischris bringe

yes its 1.7 ohms i have it going in to the amp at is that too low??chris bringe

it looks like all the power bass d-class amps are 1 ohm stable so you should be fine there. have they given you any details on what was wrong or what part of the amp was repaired? was it the power supply, inputs, outputs, etc.? if the power bass stuff is like some older concept amps you may need a higher input voltage, blew a few 2400d's a few years back and they told me the amp needed between 6-8v inputs. threw in a line driver to get upto 8v and everything was fine

How many woofers?  Single or Dual voice coil?   What is the impedance of each voice coil?

2 woffers  dual voice at 4ohms eachchris bringe

Your choices with that configuration are 4 ohms or 1 ohm.

A DMM reads DC resistance. Impedance is an AC measurement.  How do you have the woofers wired? 

i have them wired up as the diagram on hear has them shown 2 woffers dual 4 ohm is  negitive to niegitive on coils then negitive to both subs to amp then same with the positive i put my dmm on the positive wire that gose to amp and the negitive wire witch i get a reading of 1.7 ohms  thats what i hooked up to the amp i was bumping and didnt have the car running and i only have one batt do u think that could of been problem ?? its a yellow top optima but i didnt kill the batt i was just bumping for a few min then amp went to protectionchris bringe

The Optima yellow will not blow your amp - no 12V battery can. Being Optima might explain a battery failure though.... (Yes, I'm having a dig...) (At Optima!)

Seems like that is under 1 ohm load, what does the meter read when you short the thest leads together. Probably .6 to .8 ohms.
