Subthump harness
I just got my harness today. I am wondering if I should get rid of the line out converter that is tied into where the rca's would normally be? He had none left with the rca's soldered on so steve just crimped on the loc. Should I pull it off and solder in some rca's? I am worried about sound quality with the loc wouldnt it be better with just straight rca's soldered on? It has an adjustment on the box. How do I know where to adjust it? Also will the signal coming off the harness be high or low output?

I can only answer the output which is low signal for bass.

As far as crimped vs soldered, I would always go soldered. Sound quality arguments are always very subjective so it may be tough to come to a consensus there, however soldering the connection DEFINITELY adds reliability. I worked for Circuit City in their install department for 2 years and I can't tell you how many times we've had people come in complaining that a speaker would go in and out only to find out that it was because of the crimp connectors used.

You need to contact steve at ********. He made it clear to me that if anyone has any concerns to contact him directly. Send him a pm. He is very good about returning them.

The LOC is there to take the high level signal to the speakers and covert it to a low level signal. If you were to eliminate that LOC and solder on RCAs you would be pushing a high level signal through those RCAs. Check your amplifier as some amps support a high level input. If they don't, keep the LOC on.

here is what it look like

Looking at this site:
http://********.com/Chevrolet-GMC-Su...-Channels.html Based on what he says in the install video, I believe you are right in thinking that the signal is low level and that the LOC is unnecessary. At around 0:34 The guy in the video says that it merely "borrows" the signal before it goes into the amp. I don't see any reason why GM would amplify a signal and then run that through another amplifier. If you are impatient like me and have a multimeter you could quickly test it to see if its low level. Otherwise, I would take Darth_Emma's advice and talk to steve about it. |
I soldered on rca's. So it should still be low signal?

All of you are totally overanaylzing the situation. Loc's convert speaker level signal to rca. Every pac adapter out there does this. Look at all the aoem devices. Each loc has a range of wattage where they are effective. We have found that some amps need this device anyway to balance the voltage. So eliminating the unit and using rca's straight on the harness isn't going to make much difference in the final output. But ou may end up needing it anyway, depending on your amp. There is plenty of signal there to be had, even if ran thru the loc. Just FYI, if we could have controlled the cost of buying the added unit a little better, every harness would've had a loc installed and looked identical to the above. Just because it's different doesn't mean it's not going to work or you should be scared of it. Hell, I'd put that one into my car anyday. In fact, the harness we used in Darth's SS is identical to that one and it works flawlessly.

My bad, I have a habit of over-analyzing :)

What he said!! In any case, the BA system, and non BA system for that matter, carry ~6VDC in the signal to the speakers. Some amps can deal with it, some can't. The LOC will eliminate the DC current, so those amps that don't like it will run. |
