Car Audio Terms Defined:

Are you shopping for car audio via the internet and some of the terms are confusing to you?  Here is a short list of “buzz words” that I will try to explain….

DIN or DOUBLE DIN:

DIN refers to size 2″ x 8″ opening that a radio fits into.  DIN stands for Duetch Industri Normen which the Germans starting using to standardize the radio’s in Audi’s, BMW’s, Mercedes, VW’s way back in the mid 80’s.  It has since become the industry standard.

DOUBLE DIN is the same width of 8″ but is 4″ instead of 2″.

LOC or Line Output Converter:  This is a handy little gizmo that will allow you to tap into your speaker wires to grab a signal and then will choke it down to be able to be used as RCA inputs for an amp.

Some are better than others. Lets say you want to install an amp into your stock system using the.  Well, the stock deck does not have RCA outputs like aftermarket radios do so in order to get the music into the amplifier the signal has to be converted/choked down to an acceptable preamp level.  That’s why aftermarket decks sound so much better when using an amplifier.

  1. I want buy car stereo system for my FIAT UNO Diesel 1997 model. I am not sure which size would that match.Please suggest the best economic one .

  2. I would probably look at the Alpine’s starting with a CDE-143BT.We have one on display if you’d like to come view it.

  3. Hello SG2M
    I am wanting a new system for my 72 Corvette. I want it as unassuming as possible, look as stock as possible and sound like a concert hall. The interior of the car is completely lined with Hushmat Ultra sound deadening material.
    What do you suggest?
    Thanks — Rey
    P.S. I plan down the road to add Sirius XM service.

  4. This measurement of 2″ x 8″ is WRONG. The official size is 50mm x 180mm which translates to 1.968 x 7.086 ! You’re going to be very disappointed if a radio you buy is 8″.

  5. What happened to cg sized headunits? Y’all remember those right? If not they’re the r factory radio that was in between single and double din. Usually found in Chrysler/Dodge/Pontiac vehicles. Now I know I remember JVC and a few other companies making aftermarket headunits in this size back in the 90’s so what gives?

  6. Thanks for the question Heather about your 05 Dodge Ram. We have Alpine, Kenwood units on sale now that would be considered “basic” but do you have the factory radio still or do you have an aftermarket? If you have the factory radio to install an aftermarket radio would require a mounting kit and wiring harness specific to the Dodge. There are a number of variations in the Dodge that require different interfaces so the best thing would be to stop by or give us a call to be certain about what you might need for the job.

  7. We called the “CG” sized head units DIN & Half and they haven’t been made in years. All the big guys Alpine, Kenwood, Pioneer, JVC made them for awhile but no longer.

  8. In your setup menu there is I believe a “seek” option that allows you to choose whether you want the radio to seek to the next strongest station or the next pre-set you have in memory. So, go into the setup menu and choose I believe option 1 on the seek menu. Your most likely in option 2.

  9. Heather, yes we have a number of basic AM/FM/CD players that would work nicely in your 05 Ram. Depending on the Ram’s trim level, you could expect to pay $200.00 for the head unit, parts, and labor. Please stop by and check out our selection and what features the different head units offer.

  10. Hello Rey,
    For some unknown reason my earlier response to your questions about working on your 72 Corvette disappeared. Please give us a call and lets talk about your Corvette, if you are still in the market for a system?

  11. Great site. I have a 2007 ford freestar van. Will a double Din fit in place of the factory CD player unit.

  12. I have to replace the speakers and head unit on my 2001 Eurovan. I think I have seen double din units in this van so is that possible with retaining somewhat of a stock look. Also, they say the speakers are metric so there a very few bolt in replacments. I heard pioneer might have some. Since it is a pop top, it would be great to run the radio off the auxilary battery but have it turn off with the ignition. Is that possible? Someone said it was.

  13. Yes, you can install a double din and make it look “factory” and give you a bunch of new features like bluetooth, USB connectivity, etc. If I understand you correctly the speaker sizes are given in both metric and imperial so for instance a 6.5″ imperial is listed as 165mm so they are pretty much standard sizes. I would recommend you stop by the shop and let us get a look at the van and we can suggest different configurations.

  14. The Nissan “Sunny Car” is distributed in Europe and India and so to answer your question I might. It looks like it’s an Altima but not sure and have little information available at present. Best thing I could suggest is come in and let us see the vehicle and we can go from there. Thanks for asking though.

  15. Thanks for the kind words Brad. With the correct install kit (Metra 95-5812) and harness (Metra 70-5520) you can have a double din in your Van. We are always running great deals on radios so come on in and let us set you up.

  16. Yes Robert you are correct but it’s like when we say 2″x4″ not 1 1/2″ x 3 1/2″. Personally I much prefer the metric size of 50mm x 180mm. It’s crazy this Country hasn’t gone to metric like the rest of the industrialized Nations.
