[QUOTE="BCotrell, post: 8714007, member: 666314"] A couple things confuse me about your install. -the amp you chose at 4 ohm rating is probably just enough to power each pair of hertz speakers. When upgrading newer vehicles a common mistake is owners thinking they have to match/replace every factory speaker location. This is not the case and can be more more money exhausted than results realized. - you indicated your front has tweeters. Are you talking about your aftermarket hertz? I had a same year fusion as my work car and it had a tweeter spot in the a-pillar. The shop should have advised a 6.5 component set that would have replaced the front door factory 6.5 and tweeter and include a passive crossover. Hopefully that is the case. The bulk of the sound should come from your front stage. - your factory unit has built in eq that is likely filtering out Frequencies to your front speakers to “protect” them as it thinks your speakers are the factory ones that take super low power. There is likely less factory filtering on the rear speakers which is allowing a more full (not complete though) signal to your rear doors and rear de To keep factory hu and optimize result, Get a dsp with de-equalization and power two sets of speakers on the amp. Fronts should be amplified and rear deck could be too to give you sub-ish bass. The dsp will let you set filters to each speaker set. Leave your rear doors disconnected or grab a small two channel amp. this would do it on a budget but only you would eventually need to forgo a speaker set or use rca splitters on the mid channel to enable subs. If you have subs though the rear deck wouldn’t be necessary. [/QUOTE]
