- New to the community and looking for advice on an upcoming install in my 2006 Honda Civic. Specifically on the sub ( have decided going with a single 10" sub in sealed box) , components in front door, and amplifier. I'm thinking about the Arc Audio x2 850.5. Had one in the past and bridged channels 1-4 for components and 5 was used for a 10" W6V2 in a sealed box. Setup sounded somewhat impressive. Anyway just looking for suggestions on brands known for SQ and similar in price to JL and Arc. Been out of the game for quite awhile and could use some help cause I'm pretty excited to start this install!!! Thanks in advance!
