I tapped the sub and only the right front speaker. You would need a 4+ channel LOC with signal summing if you want to tap both front speakers.
Are your amp connectors RCA or high level input? Most high level input on amps have a upper limit of 10v. There are a few that can take up to 40v...
You can use a calculator to check what RPM you should be at in each gear at a specific speed. Typically people jerk when downshifting into second gear because the gear gap between first to second and second to third are a lot bigger than the rest of the higher gears.
How would you mix the output so the navigation only goes to the center? If you properly tune your dsp you should be able to achieve a sound stage where the sound appears to be from your dash anyway.
From a SQ point view, a mono center stage is not a good thing. If these cars had 2 spots for...
In that case hook it up to the front speakers and measure factory amp to see what you have to work with. Base audio system probably still have a roll off for the front speakers. Use a voltage meter to measure ac current and play test tones from 30-80 to see what kind of curve you are dealing...
I recommend tapping the sub + one of the front speaker. With the equalizer on the head unit all in the middle and the factory sub set to 4, this is the measured output of my amp with a 24 hz subsonic filter and a 24db/octave low pass filter active.
Tapping the sub only gives you a nasty peak...
Are rear speakers and center speaker necessary for your usage? If you don't have people in back seat rear speakers don't really contribute to a good sound stage, and center speaker aren't really necessary for a perfect good stereo sound stage. You can use the first 4 channels on the LC6.1200 to...
Are you going to be using an amp for your speakers? Just replacing factory speakers isn't going to be very effective. Factory DSP have terrible equalization so you really would want a DSP or a DSP amp for your new speakers.
In order to get reasonable bass from door speakers, you need very good...
I suggest you use a DSP or an DSP amp instead of viper4android or lci6. lci6 ONLY have signal summing, it will not fix the factory EQ on the premium. Kicker Key 4.200 is a good DSP amp for $250. You hook up your front woofer/tweeters high level into it and it will automatically flatten the...
For people still looking for options to fix the pathetic attempt at pReMiUm by Honda, I have some good solutions. OP has done some wonderful experiments and I have a pretty clear idea of what the faction premium system is doing.
A full 6 channel DSP for the front woofers + tweeters + subwoofers...
