i replaced the rear speakers and fronts were still stock and the rears put out about half the db as the front. The highers were better but the bass was horrible (nothing) and i had to turn up the volume near and above 30 to hear the same level i did out of the stocks at 20 (on the volume control #). So i put stock speakers back in to research why i had such a big difference.
Most likely because the rear speakers are crossed over and not full-range. You can run into a multitude of problems with speakers firing up into the rear glass. Cancellations, more rattles, etc...something Honda most likely knows and wants to avoid. What were the speakers you replaced the stocks with? I would venture to say they were quite a bit LESS sensitive than the stock speakers.
I was hoping to replace interior speakers and run them off the head unit and add a LOC for a small amp/sub.
The higher freq of the stock speakers **** and therefore why i would like to replace them.
The high frequencies of the stock speakers **** because they're cheap and likely measure horribly on and off-axis. There are certain things you need to look at when replacing speakers and it depends on the location where you're putting them too. If I can give one piece of advice, it would be to ditch the rears and put your money into the fronts.
It seems a simple speaker replacement and add sub/amp is not a simple task. It seems if i want to replace the interior speakers i need to add and amp too and a LOC big enough for 5 channels
A front speaker setup, amp and sub should be relatively easy. Tap into the FL and FR wires BEFORE the factory amp, run that into your amp and wallah...you're done. You'll loose the rears, but again...that's just my advice. If you can, find an amp that can take the input voltage without needing an LOC (not sure what the voltage is BEFORE or AFTER the factory amp...I'd LOOOOVE if someone knew).
So does Accord Sports have a factory amp? WOuld 2 ohm speakers give me a better db output with stock head unit?
Not sure. I'd assume so. If you find out, please let me know. My car is too new to start pulling panels lol.
Going down to a 2ohm from 4ohm (thanks GTP for letting us know the stockies are 4) will gain volume, but I HIGHLY doubt the factory amp is 2ohm stable.
Im a little confused as many people have swapped out interior speakers and never mentioned amps or LOC
If you can, you don't want to use an LOC, but if you have to..it's for an amp and to gain some voltage (on some particular 'loc's')
You can swap the speakers without changing anything else, but factory speakers are usually very high sensitivity speakers so they can use a small amp. I might be able to find something that would work well in our cars if I get some free time. If I could find a high sensitivity 6.5" with good off axis response and shallow enough to not make modifications, I'm sure people would like that. I'll see what I can do
Stock rear speakers in the sports are 4ohms. I have tested mine with a multimeter.
I experienced the same thing when in went to replace the stock speakers with some Polk components. I can to the conclusion that the stock head unit does not push enough power to run the aftermarket speakers.
If I can figure out how to measure rms with a millimeter I will test it out.
Thanks for that. Have you taken a look at the fronts? I would assume they're also 4ohm, but just checking.
Again, you replaced the factory speaker (high sensitivity) with another speaker with low sensitivity. That alone will cause a loss in dB's/volume/SPL.
What people also don't understand is that just because an amp is rated for say...50rms, doesn't mean you're using it 100% of the time. Hell, not even 50% of time most likely. Dynamic peaks in music when listening at a decent volume, sure, but most of the time you're using minimal power.
