Installing components w/o an amp or crossover

TXSpeedDemon · 07-13-2012, 08:02 PM

Thanks Nate.

So do you think I could wire the crossover off the current woofer's wires (and route that to the tweeter) to avoid pulling out the headunit or is there no getting around it?

Edit:
He just brought over the speakers for me to look at. Looks like the crossovers are only for the tweeters. In the package wiring diagram they have wires running straight from the amp to the woofer. Then you hook up the supplied wires with the in-line crossovers to the woofers and run those to the tweeters. So I think I can try tapping the stock tweeter wires into the new ones (with crossovers) and to the tweeters. That should help make the install faster and easier

The only problem I could see with that is your stock woofer may have a low pass filter at the amp, matching the high pass at the tweeter. Not likely, but possible.
Lets say your woofer has a low pass at 1800hz, and the tweeter has a high pass at 1800hz, now you wire your aftermarkets in, so your woofer still cuts at 1800hz, but your aftermarket tweeters crossover is high pass at 3000hz. You would miss out from 1800 to 3000hz. Probably not as great issue, but if you are a discerning listener, you may pick up on it.......

I used to have an 8th gen civic.

The tweeter does have a capacitor. It is receiving full range from the Amp (the honda civics come with an amp below the deck just in front of the shift lever).

The stock woofer also gets full range.

Thanks for the input guys. I ended up running it off the new woofer as the installation instuctions said and left the stock tweeter wires untouched. This will make it easier if he ever changes his deck or wants to put his stock speakers back in to sell.

It worked great and he's happy. thanks again for the advice.
