Icon5 Does anyone understand what this is?

Alright so I installed my new radio, I removed the "peripheral" that was used to adapt the RCA's of my amp for my sub to my factory radio.

This is all intact and I would like to know if any of you guys understand how this works or would interested in buying it, or if it can be sold as is.

Don't sit here and tell me this doesn't work or is junk. I've had this for 5.5 years and have had ZERO problems with it. The sub has sounded great.

No I don't have the owner's manual

The peripheral brand thing is called a line out converter. The stinger things are "bass blockers" and I have no idea why they would add those inline with the wires going into the LOC. They're crappy to use in the first place but I have no idea why they would put them on the wires sending signal for the sub since they block lower the lower frequencies that the sub is supposed to play. Their purpose is for door speakers so they don't distort.

Would the filters have anything to do with it being a bridged 2 channel amp?

Do the settings on the amp (gain and frequency) have something to do with it?

No. The filters are for door speakers or tweeters depending on what ones they are. They're basically crappy high pass filters, they block all frequency from 0-whatever Hz depending on what model they are and what the ohm load of the speaker is. These were wired going to the input of the LOC right? Makes no sense to me. And the frequency setting on the amp is similar to what they do except it is a low pass filter, so it blocks all frequency higher than whatever you specify. For example I usually leave my LPF on my amps set at 80hz, so anything higher than 80hz doesn't play through the sub.

Thanks for the help Korey.

Your system should sound a lot better without those in there. You will be happy

One last question. Would this be worth trying to sell, or should I junk it?

purpose of a line output converter is to take a high voltage signal and reduces it to a lower voltage that rca of an amp can accept. your gains will be different now that your using a different signal source.

If you have rca outputs on you head unit you should always use those instead. its a cleaner signal.

those capacitors have to be acting as a lowpass filter if they where on your sub.. just make sure your using either your head unit or amps lowpass filter now, otherwise you're sending high frequencys to your sub without them.

The unit is working fine, its just that I got a new headunit that has 3 sets of RCA's, and I don't need that thing

Anyone think that I should sell it?

I would expect that most people upgrading their sound system with a sub and amp will probably be getting a new headunit anyway

im sure someone could use it.. but its kind of a small niche.
most amplifiers have high level inputs already.
It would only work for someone with a factory hu and a rca only input on their amp.

Sell it since you seem to really want to get rid of it. (I would just toss it in one of my storage bins and hold on to it in-case I needed it later for whatever reason)

That's a good point, it's not a huge thing, might as well hang on to it. I'm sure somebody will want it.
