This Rockford Fosgate adapter lets you connect the speaker-level outputs from your car stereo to a compatible amplifier with RCA inputs that will accept a high-level signal. Once you've connected your speaker wires to this adapter, you'll run RCA patch cables (sold separately) from the adapter's female connectors to your amp. Oxygen-free copper wires and platinum-plated connectors resist corrosion and ensure good signal flow. Warranty: 1 year
Average Customer Review(s):
Does exactly what it is supposed to do.
Pros: Well made
Great quality and super fast shipping.
Pros: Rockford fosgate qualty Crutchfield fast delivery
Great well made product!
Pros: Well made.
Easy solution to put PBR300x1 back to line level input, because who know where the cutoff went
Pros: Quick fix
Great product, it saves me a lot of headache. a life saver
Exactly what I needed and easy to install. Fast, courteous purchasing and shipping.
Works as intended. Had an issue with the amp I connected this to, but it was not this products wrongdoing.
Pros: Works as intended
Worked very well for my particular application. Great signal now going to my 4-channel amp!
Pros: Easy to install, great signal
Speaker level inputs use existing speaker wires to send input to another device, usually an amplifier. Every amplifier I've bought in the last 30 years has FEMALE RCA inputs and outputs. This product converts speaker wires to Female RCA's. No way to directly plug into anything without buying another set of Male/Male RCA cables. This requires an added connection and longer lines. More connections and cable length is bad ju-ju. Product should be speaker wire inputs to MALE RCA'S. I didn't pay attention and now have to go buy an additional RCA.
Pros: Absolutely none unless you just like making unnecessary connections.
These Rockford Fosgate speaker adapters were simple to use. Wired them in place of the recommended KISL's and they work perfectly...simplified my application fit use on Kicker Hideaway 8" powered subs. Great product at a fair price...at a fraction of the price of other speaker adapters.
Made connection from the wired speaker terminals of my reciever to a SONOS connect easy.
Pros: They worked like a champ. Joined the two negative cables and grounded them then hit the positive wires running to the rear speakers and boom, out comes the sound!!!! Saved me around $60 by going with the pre made adapters. They went in a 2010 Camaro SS.
Cons: Nothing at all.
Pros: needed this for my P10-300 after using the high level speaker inputs just rebutted the wires and was good to go
Easy to use and great quality. It actually has a wiring diagram that helps you know what to do during installation. I rejected all others because of this.
Pros: Detailed information. Great quality.
It's a great product to put my subwoofer amp and easy installation
Pros: Fast shipping and great product A++++ don't need to take my stock radio
exelent wire speaker work good
Speaker-Level to RCA Adapter: This high-level speaker wire to RCA adaptor (RFIF2SW) from Rockford Fosgate lets you connect your vehicle's factory radio or an aftermarket head unit without RCA outputs to an aftermarket amplifier which lacks speaker-level inputs. The speaker-level to RCA adapter features 4 bare wires on one end and two female RCA jacks on other end.

|White/black wire||Left Front Speaker Wire (-)|
|Gray RCA||Right Front Channel of Amp|
|Black RCA||Left Front Channel of Amp|
Twisted Pair Constructions: Each RCA channel is twisted, alternating the positive and negative conductors, to help reduce noise for enhanced sound quality.
OFC: The speaker wire leads and RCA cables use Oxygen Free Copper for corrosion resistance and excellent signal transfer.
Platinum Plated RCA Jacks: The platinum plated female RCA jacks resist corrosion and offer excellent signal transfer.

Need to connect amplifier[ Alberto Jan 26, 2017 ]
Customer support[ David Dec 23, 2016 ]
I have an older deck in my truck and this allows me to put a subwoofer in without replacing the deck.[ Wyatt Andrew Dec 01, 2016 ]
Connect Punch amp to factory stereo[ Jonathan Nov 30, 2016 ]
I don't have a RCA port in my radio so splicing into my speakers with this will allow me to hook up my Amp[ Andrew Nov 14, 2016 ]
Tech said I needed it but then I ordered the wiring kit afterwards and probably don't but was keeping it in case.[ Jeff Oct 10, 2016 ]
because i got the rockfprd speaker[ JAMES Oct 02, 2016 ]
Because I need it for my amp hookup and splicing into my existing factory amp.[ Wayne Sep 30, 2016 ]
needed[ Patrick Sep 04, 2016 ]
Needed speaker level inputs and the amp I bought was Rockford Fosgate.[ Paul Aug 19, 2016 ]
I want to connect my factory sub amp that has speaker in wires to the sub pre amp rca of the head unit[ Karsten Jul 16, 2016 ]
I had bought several Rockford Fosgate car audio equipments in the early 1990's and their quality were, and are as good as other brand such as Alpine and JL Audio. The price are reasonable and importantly you get a good product.[ Khamsing Jul 11, 2016 ]
affordable and it is just what i need for my installation[ matt Jun 20, 2016 ]
Worked well for my application.[ SHAWN Jun 08, 2016 ]
Powering aftermarket component speakers with an amp that accepts speaker level inputs, but needs them converted into rca inputs.[ Parker Jun 01, 2016 ]
Current radio has a Sub-out with an RCA ran back to a Rockford P300-12. Bought the JBL Legend CP100 and it does not have a Sub-Out. Bought the Audio Control LC2i and will use this with the current RCA to plug into the LC2i.[ CHARLES Feb 14, 2016 ]
Looks like good quality and the price is reasonable.[ THOMAS Jan 20, 2016 ]
Did not read that. Piggybacked off my stock amp to my new amp. Grounded both to the frame and it worked.[ Dawid Feb 19, 2016 ]
Can you this set up for house speakers? If so, how would you connect it? [ willie Jul 23, 2014 ]
Yes you can. In my installation, I used this product at the wiring harness leaving my head unit. I spliced into the right and left rear speaker wires. I then connected my RCA pre-amp cables and ran them to the floor, under the carpet and back into the rear of my Jeep where I have my powered subwoofers. This is a great product for keeping factory "non RCA pre-amp output" head units if you don't want to or your budget doesn't allow. In essence, I now have a head unit with RCA pre-amp outputs.[ BRIAN Jun 11, 2014 ]
This will depend largely on your amplifier. If your amplifier can accept a high level input on the RCAs then this will work great. Otherwise you would need a live level adapter to step down the speaker level output to RCA level. I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They should be able to help determine if this is compatible with your amp.[ Jeff Jun 09, 2014 ] Staff
Only with certain amps that accept high level inputs through the RCA's. I think some RF and Kicker amps have the feature. You would have to check on others.[ SHAWN Jun 08, 2014 ]
Yes, that is very do-able. I use them the other way around. I connect the bare end to the speaker terminals of an amplifier and hook the other end to speakers with male rca plugs. Either way will work.[ robert Jun 07, 2014 ]
Only if it's a factory subwoofer, if you're connecting to your rear speakers you need a level line converter or the factory head unit will cut off the sound since it senses a high resistance and it'll try to protect the speakers.[ SONNY Jun 06, 2014 ]
Yes, that is the exact purpose of these wire kits. It's for a situation where you have a factory deck that you can't (or don't want to) remove but want to hook up an amp and sub woofer. Without an after market deck you don't usually have anywhere to hook up your RCA sub woofer wires, so that is where these get used. You can hook this harness kit up to your car's rear speaker wire harness and then plug into your amp's RCA cable input from these wire splices.[ CHRISTOPHER Jun 06, 2014 ]
Yes nick you can that's exactly what I did on my 2002 lexus gs 300 with premium sound and it worked.[ CHRIS Jun 06, 2014 ]
Yup, you sure can. That's what I did in F-350.[ RYAN Jun 06, 2014 ]
This will depend largely on your vehicle. For details on installation please contact an Advisor by phone (1-800-324-9695) or online chat. They will be able to pull up your vehicle and give you the details on what you will need for an installation.[ Jeff Feb 21, 2014 ] Staff
