Once you set your gain properly you should be fine.

 

Ok so those max dimensions you gave would do 2 fi q 15's optimal ported, do you have a specific tuning freq? If you dont know I can suggest one, Fi suggest 28 to 33 hz.

What type of civic do you have, sedan, coupe, hatch?

What is your prefered sub and port orientation if you know? If you dont know I can make suggestions.

 

Nothing wrong with those AQ amps! Can't be beat for the $ IMO

 

Absoletly, they are good for the money.

 

I'm pretty new to the customizing my system, so I don't have any idea about port sizes and how they make a difference. Suggestions would be very much appreciated. As far as my civic it's a sedan and the backseat can fold so I'm pointing these guys right at the back of my head, bass-face here I come.haha

Thank you very much for the help

 

No problem I will hook you up.

 

Completed and in you pm.

 

Box for the fi Q's tuned to 32 Hz

 

That looks amazing Sonic! I appreciate it a lot, especially when you had little time to do this request, I just can't thank you enough. I wish I had your knowledge and understanding for these things so I too could help others.

 

You are welcome mann !
