Not sure about power rating, but the following post mentions a tip for upgrading the speakers without cutting:
Possibly, it really depends on how the head-unit outputs to which channels. Obviously the center speaker gets one channel. Question being does the factory system use a crossover for the fronts (mid-range and tweeter). If yes, than 2 channels front, left/right. The rears are probably a co-axial design, so 2 channels for the rear. One channel left over. Should work in theory, and allow you to turn down the gains of the center channel to help correct the sound staging issues, and over-powered center channel.
In the first thread recommendation provided above, @INSIGHT_OUTTASIGHT used a 6-channel 'Audio Control LC7i' to upgrade the EX system. - https://www.gen3insight.com/forum/2...g-system-module-active-noise-cancellatio.html
The major difference is OP has a touring, different speaker set up than LX/EX cars.
You'll want an amp with speaker level inputs and with summing ability or you need to get a line level converter to switch the speaker inputs to line level inputs. The audio control stuff has some summing abilities and can restore lost bass the system chokes to avoid blowing cheap speakers. I have a fair number of videos about my exploits with the touring sound system on you tube on my channel verdier 400. I'm going to have the system tone tested on Monday to figure out what amps to get. I'll also be getting a DSP to fix the horrid eq levels. I may need to get 2 amps to push all the speakers since I'd like to run active so I can time align all of them to my seating position.
Might be loud enough, but if the system is cutting lows out at higher volumes which many do, then you'll need to recover the bass that's cut otherwise your sub won't be as effective at higher volumes. Find out if the jl system has the ability to recover system choked bass first.
Is this due to the communications (can-bus system)? Just curious.
As far as i can tell they've hooked the entire audio system's control into the amp itself so if you tried replacing it you'd probably lose function in the display and definitely steering controls. No one has made an interface yet that can do a bypass on this amp to keep control with replacement amps. The audio control stuff can bypass this with line converters but only after the amp, not before. At least not yet. To make matters worse, as far as I've been able to discern, this is the only car that uses the amp in question so a bypass may take a while to be made since we're talking about a smaller number of cars. Maestro and other companies have to think they're going to make a profit before they invest in making a bypass unit.
There are plenty of amps to use with systems like this. You just need to use either line converters or amps with speaker level inputs. The only thing holding me back is because I want to use a DSP and make all my speakers active so I going to a pro for advice and more info on exactly how many channels the car REALLY has rather than what Honda says it has. If you're waiting for a direct connect input like a maestro component then you might be waiting a while if they make one at all. This car is selling well, but not like an accord and the aftermarket companies have to justify the cost of making such a device. Right now I have all new speakers along with the sub being pushed by an audio control amp. I have full control of the system through the screen with no hiccups. The problem I have is the DSP settings built into the current system is way too shrill at the very high volumes I need to play so I have to run an external DSP to flatten the frequencies so I can listen to it without losing tooth enamel. I go in on Monday for a more thorough evaluation of the system so keep an eye on my channel and I'll let you know what happens. Let me waste my money being the guinea pig and I'll make all the mistakes for you. I'll let you know everything I find out so the rest of you can do an upgrade with less troubles. I won't treat it like a national secret. I like helping the community if I can. Feel free to message me, and if you wish, I'm willing to talk to people on the phone if they need info. Take care and don't give up!
No problem. I'm looking forward to my meeting on Monday and I hope this guy can help me figure out a system that can play at high volume without peeling my skin off with incessant screeching.
