Great build quality

This 8 inch Idq has really impressed me with sound quality. Using 400 watts in a .75 down firing enclosure in the rear seat floorboard it is incredible. Using it in my daily driver 06 civic, amps under both front seats, 4 sets of 6.5 components in doors and rears deck. I have nothing in my trunk and it baffles people that ride in the car. Looking to add another.

Great sound

I would definitely recommend the imagedynamics ID8 . it's got impressive sound qaulity and response . I had a re rex 8 and this thing kills that. I have it in a 02 camaro to save space and it's perfect for that . most people think I got a big 10 inch sub . makes me laugh. Gotta have a the right box box tho.
