so let me start off tell you what i have ....i have a 98 taurus GL...my headunit is a eclipse cd3200...i have a clarion EQS746....a eclipse ea3422 4 channel amp with the front channels running a set of PPi 3 way powerclass components and the rear channels bridged to 1 channel running 140 watts RMS into a single clarion 10 in a 0.7 sealed box. so far my mids and highs are good. imaging and stage is all great. i can adjust my sub so it bangs clean and loud. but what i want to know in a true SQ comp car is the sub really heard at all?...like dose it just fill out the low end? or do you hear the sub banding in the rear at all?
