I Have 2 Kicker Solo-Baric S10L7's, And I know I would get better sound for in home use with a pre built home Audio Sub but this is a project I've been wanting to work on for some time. so my questions are If I used an open cabinet what size power amp would I need? What brand do you recommend for a power amp? How do I go about not mismatching the impedance and stay above 4 ohms? Does it matter what type of In line high pass filter I use? if so what brand do you recommend for the fiter? any suggestions would be greatly appreciated thank you!
