So I realized that my hifonics amp was a POS trying to play with that all day n never being happy I sold the amp and my L7 and ive got about $600 to spend on some good sounding bass. I've got no problem buying off ebay or anywhere online, even something used if its nice. I'm a big fan of JL Audio, Phoenix Gold. even kicker, but what are some prices and amp/sub combos you would reccommend. Single sub is fine, dual sub works. 10's 12's 15's....whatever. I usually listen to rap but I like having a really clean bass. Thanks.
