[QUOTE="OtisWallace, post: 8740740, member: 682659"] The details: Crutchfield helped me put this ensemble together for a 2019 Subaru Crosstrek which consisted (prior to my installation) of door speakers (front and rear) and 3.5 inch dash speakers. What they recommended, and what has been installed is as follows: Dash: JL Audio C2-350x [URL]https://www.crutchfield.ca/p_136C2350X/JL-Audio-C2-350x.html?awcp=&awcr=191354367296&awdv=c&awkw=c2350x&awmt=p&awnw=g&awug=9001395[/URL] Front Doors: Focal 690 AC (2 - way-coax) [URL]https://www.crutchfield.com/p_091690AC/Focal-Performance-690AC.html?tp=91[/URL] Rear Doors: Morel Maximo 602 Ultra (2 - way coax) [URL]https://www.crutchfield.ca/p_210MAXIU62/Morel-Maximo-Ultra-602-Coax.html[/URL] Dash speakers are powered by headunit (probably pushing aroudn 15 - 20 watts). Headunit goes through an LC7i LOC into a 4 channel pioneer amp (100w/channel @4ohm) that powers the four doors (Pioneer GM-DX874) LC7i has accubase threshold set to max (as to ensure the factory subaru stereo does not roll off base) Pioneer amp has HPF set to ~80-90Hz for both front and rear channel. This was professionally installed and I have to assume that the signal path from Headunit --> LOC --> amp gain has been done properly. I have 2 primary issues. 1) Everything is a bit bright. To combat this I wish i would have gone with components but that is not what was recommended. There is so much energy in the mids and upper frequencies because there are tweeters everywhere (at least this is why i think this is occurring) 2) lower frequencies are either non-existant, or distorted - which leads me to believe I need to adjust HPF (but i dont see how this helps because i likely wouldnt go lower), So my question to all of you brilliant car audio minds. If you were struck with the above, how would you correct? Money can be spent but must be spent appropriately given the situation (ie: im not going to throw good money after bad). Also, i want components under seats and not in the hatch...with the exception of a sub, should i go this route. Examples of things im questioning......... a) scrap the front door coaxes (sell them off) and start again with components. b) keep as is and add powered sub c) keep as is and replace 4 channel amp with 5 channel amp and add a sub d) add a dsp and roll of the high freqs somewhere in the system e) Scrap the 3.5inch dash tweeters because they compete with the frequencies of the doors f) get an amp with a band-pass filter and tune one of the door channels to become a midbass g) dynamat doors to help control the energy h) etc. Im open to suggestions. Thanks All! [/QUOTE]
