Aftermarket subwoofer with stock HU?
 

One of my friends is looking into getting a little system in her (I think) '02 Accord sedan...nothing crazy, 1 Memphis 12 in a ported box on a RF 300w amp. I've seen people install an aftermarket HU in the little console beneath the stock one (in that little cubby hole)...but I seem to remember hearing something about a crossover cable that can be used with the stock HU...can somebody point me in the right direction because I've come up with nothing.

Thanks in advance https://honda-tech.com/forums/images/smilies/emthup.gif

Scratch that, 2003

UR soo wrong. https://honda-tech.com/forums/images...s/emsmilep.gif
U dont need a "crossover"
thats something else.
If u want to keep the stock HU and use an amp:
You need to get an LOC (line output convertor) and connect it between the bose speaker wires (light green and green/white stripe) and the RCA inputs of the amp. You can also connect the remote wire from the amp to the stock remote wire (as said above). Run power wire from the battery to the amp, and ground your amp and you should be good to go.

uh what?

Re:
 

Accords don't use a Bose system, and there is no "stock" remote wire.

I realize I used a wrong term...but according to the other two posters, you're inventing wires.

Anybody have a link for a line output converter?

or search ebay for Line Output Converter

You could use a relay or a switch, it depends which you'd feel better doing.

Re: (sony224422)
 

Don't those take the rear speakers and convert them so that the amp can be used? Won't that cut back on the sound quality?


What about something like this? (I'm just used to putting in new HU and wiring up subs and speakers...nothing past that really)

Re: (JKov240)
 

JKov240,

Where in Texas are you? I have one sitting right here that you can have for free.

EDIT:
All you need to do is splice into existing wires. You can still use your rear speakers.

Re: (philadd)
 

Orange...100 miles east of you on the TX/LA border.

Thanks dude https://honda-tech.com/forums/images/smilies/emthup.gif


EDIT: But won't that kinda...cut the rear speakers out some? Due to them sharing a signal

Re: (JKov240)
 

I haven't met anyone that noticed a difference yet. If it does, you can just turn the fader to the rear a bit to compensate.

Just keep in mind that using the stock headunit is what is going to kill the sound quality. However, if she's just looking for a little more bass and nothing window-shattering, she probably won't notice the difference in quality.

If you decide to install everything using the converter, send me a PM with your address and I'll send it out to you. (Of course, if you're not going to use it I'd rather hold on to it. https://honda-tech.com/forums/images...s/emsmilep.gif ) Or if you happen to come to Houston for some reason, I'd be more than willing to meet you somewhere.

Re: (philadd)
 

yeah, philadd is right.


aftermarket is going to sound the best.

Stock isn't going to sound the best, i used to have it and it got the job done, but i upgraded and i'd never go back to it again.

Re: (sony224422)
 

In my truck I ran a sub with my stock headunit for a while and it sounded pretty good. You either need an amp with speaker level inputs or a line output converter like stated above. I had a amp that would accept the speaker wires and still used a loc anyway as one was left in my truck when I bought it. For the remote turn on I hooked it into the fuse box. Just find a fuse that has switched power and hook it into that.

yep.

just keep in mind you won't get the options or the ability to tune it very well. you'll be limited.

Re: (sony224422)
 

I realize that aftermarket sounds better, but she's a girl (no offense to any ladies on this board) and she's the kind that wouldn't really notice a difference...and she just wants a little bit of bump, nothing crazy.

My other question is...let's say that I do use the line out converter...what about the remote wire on the amp?


EDIT: the RF amp that I picked for her has the little remote bass controller...would that make tuning a bit easier for the sub itself?

Re: (JKov240)
 

those things are like the gain on the amp. yeah you could turn it down all the way or turn it up, but if its not tuned right you'll start to clip.

and for the remote, use a relay and wire it to something thats on in the I or II position of the key.

Re: (sony224422)
 

There's really no need for a relay.

Re: (philadd)
 

Explain please, lol. https://honda-tech.com/forums/images...s/emsmilep.gif

its just a safetly measure. you don't really need one, you could just tap into a wire thats in the I or II position

Re: (sony224422)
 

I don't really see how you view it as a safety measure...

Re: (philadd)
 

Get one of these

Then go get one of these

Do not buy this part. You simply want to know what pin on the main harness is the blue/remote on the adapter harness.
That is for your remote, splice that wire on the OEM harness to the remote on the amp.

Simply hooks up. Plus the back of the adapter harness will say what is remote. Make sure you remember what pin it is on the Main harness.

The other part is the gain control on the amp, yes this allows for tweaking. However it would think its useless since your gain control on the amp is going to be enough, for this rigged setup..

Or instead of having her be cheap tell her to run and buy a cheap radio with preamps.

http://www.bestbuy.com/site/ol...02151

Here, then run RCA from Deck to amp, buy said adapter above and have Remote to amp, then battery to amp, then amp to ground, Simple. Also sound will eb cleaner and no splicing and hack of the main car harness.

Why does everyone have to be cheap, audio quality will suffer using LOC. If all she wants to do is go BOOM BOOM she will like the cheap approach. Otherwise is she wants it to sound decent tell her to do it right and invest in a deck

because instead of having a huge burp of power when its turned on, you'd want to relay it. not saying that a remote wire takes alot of current, its just a safey measure.

Re: (B18C1 '96 Coupe)
 

One of the first things you need to understand is that just because YOU demand a higher quality sound in YOUR car, it doesn't mean that everyone else does. Most people out there do not need that much audio quality. Many people out there are completely sastisfied with the stock stereo. Some just want a little more bass. Most of these people would not hear the difference in quality if the subs were run of the stock headunit vs an aftermarket headunit.

The stereo and climate controls are combined into 1 unit in 03+ Accords. The cleanest looking option when installing a new deck is to utilize the storage area below the stereo. This is the same location that Honda uses to install any optional audio equipment. Many people still don't think that this looks quite right and would rather use the stock headunit.

Okay, I see the point you're trying to make, but it's really overkill. There's not going to be a huge "burp" of power.
