Id recomend either Boston Acoustic or MB Quart speakers

i myself have Boston Acoustic FX series front and rear, and even when i have my Sub (JL W6 =D)muted, it sounds like i have a sub, and thats just coming from the headunit, i can oly imagine what they'd sound like amped.. just my 2 cents

ohh and it would probably help if you gave an estimated budget. Because then I could think of different companies yada yadda
