i just installed 2 12" Rockford HX2 Subwoofers and a 1300 watt Rockford Amp in my 2003 Toyota Avalon XL.. let me just tell u it was the hardest thing to ever do because it took 3 days and i had 3 people including myself doing it.. but it was worth it cuz it sounds amazing in the huge trunk.. if you want pics i will post them

yea.... post up some pics.... i wanna see. i had 2 12" Kicker Solobaric with a 2000 watt amp. it was alright.. but the box wasnt big enough. sold the whole system and now tryna get me some JL 12' W7.
