I have a 2013 Accord EX-L with the factory 360 watt, 7 speaker system. I am going to install the Alpine PDX-5 5 channel amp, replace all speakers, and also add a 10" sub. Do I need the Audio Control LC6, LC7, or neither? I know that the PDX5 has low level inputs, but does my system benefit from the LC6 or need the added bass restoration of the LC7? If it does not need it, then I would rather invest the money elsewhere. If it does help, then I will get it. Please keep the suggestions to these two models, or to another device under $200. Thanks for the help!
First you need to know what the voltage is of the wires you're tapping in to. That will help you figure out if you need something to boost the signal to an acceptable level for the amp or not. I've asked this in multiple threads on here, but no one seems to know what the voltage is before and after the factory amp (or just straight from the HU on the LX & Sport models).
Someone mentioned below that Honda uses balanced. If it's anything like the '04-'08 TL's then it's a balanced differential signal. The easy remedy is to use the Rockford Fosgate BLD. I used it and still have it. Good little unit for sure.
Either way...save your money on that unit. Put that towards full blown DSP later down the road.
I basically did the same as you in my 2013 EX-L . My installer recommended the audio control LC8i to go to my alpine pdx 5 channel amp . I replaced all speakers and added a sub. It sounds better than stock, but still sounds off. After some research my installer just hooked up the speaker level to the LOC, this is NOT the way to go . When you do that the signal is getting amplified and processed by the factory amp then summed by the LOC then amplified again by the alpine . This is a recipe for bad/weird sound . Somehow you should bypass the factory amp . A good installer should know this . The honda has balanced outputs and only some amps will accept this . I recommend to do the research and find a installer or you that knows what there doing . I'm on a waiting list of a top US installer to basically get everything ripped out and put some higher end gear in the honda.
Are you positive it has balanced? Just making sure
The thing that we did in the '04+ TL's (they had a factory amp with balanced diff. signal too) was to splice into the signal BEFORE the amp. You DO NOT want to splice into the signal AFTER the amp as you're getting a signal that has already been crossed over and amplified. If these cars are anything like the TL, which I assume they are, the pre-amp signal or the wires BEFORE the amp are low voltage and full-range. Those are what you need.
That is easy enough to figure out. When you turn up the volume, does the bass start to decrease? My '07 does this but not sure if yours does or not. If the bass starts to decrease, then you want the accubass.
Acura implements something like that also so they don't have to cover blown speakers constantly. Granted it follows how humans perceive sound relatively closely, but that's not why they did it lol. This was measured within the TL community and the amount the signal changed AFTER the amp in regards to this was minimal. I wouldn't worry about it. Nothing EQ or DSP can't fix.
...it's probably a good thing for the 99% of people that think the subs should be at 90+db on a reference level tone lol.
Too the Assh*ole that recommmended all these fancy equipment. I was in a budget and went and bought a regular 4 chanrel scosche loc at Wal-Mart and it works just as good as my audiocontrol lc2
Any LOC ****s. No way around that.
Uhmmm bro, before you go on a rant. Please read it over a few more times. Simply implying the audio control units are just overpriced garbaged. Before the op invest money in these expensive unit try out these 15$ line out converters if u will. If accu bass is a must than go with audiocontrol if not just opt for the scosche 4 channel, they work just as good.
The Audiocontrol units are definitely better than most out there, but they're still best avoided if possible.
