I have 2 Polk Audio Sr124 subwoofers. They have been pretty good and all but im sick of the tinsel lead problems i have been having with them. Im looking to get 2 other subs, but i need some help finding good ones. Im still looking for sound quality while still getting loud. Here is the amp that im currently working with:http://www.alpine-usa.com/US-en/products/product.php?model=MRP-M1000. Im looking for subs that will take full advantage of the amp. Thanks for any help.
