electrical connecters on subs/ 1 blown sub

[thatsmydawg]

i have 4 12" fosgate p3 subs with 2 old school punch 800's and 2 of the subs since day 1 didnt work. i took the covers off the connecters on 2 subs and it looks like the connector was defective on both subs where it bolts up to the quick connect was broken.where can i get them there 90 degree bent eye terminals with a solder hole at the top? and also i think one of the subs is blown it makes a crackeling noise when the bass hits. but when i push down on the sub the littlest bit it goes away and sounds fine
