Resistors for adding an amplifier?

[Mike77]

I'm trying to do my homework before ordering everything to add a 4 channel amp to my 2015 ram 1500 crew cab. The truck has the 6 speaker non alpine system in it. I want to add a 4 channel amp to run the front and rear door speakers.

From what I understand, in order to add a 4 channel amp to push the door speakers, I will need to add resistors to the speaker inputs for the head unit to sense a load in order to send a signal? Is that correct?

Are there line output converters or 4 channel amplifiers that have this feature already built in?

Sorry for all the questions, I'd just rather do my homework up front rather than chase problems on the other end. Thank you!

As far as I know, the resistor thing only applies to the Alpine system with the built-in factory amplifier. I know this because I fought with the damn thing for months until coming across a post somewhere.

You should try to keep all of your questions in your original thread. It will make it much easier to find later and also for people to read back in order to help you solve any problems that crop up.

Thank you, I'll see if I can combine them.

it also applies to the non Alpine systems, I'll have to check which ones I used for mine

Speaker Resistors - 37 to 50 ohms, 5-10 watts

by they way, I went with 47 ohms, 10W and all works great

I didnt use any resistors with my 2014 non alpine. I also have my amps all high level so they are straight connected without a processor/eq/dsp in the middle. This might make a difference but in any case, 0 resistors here, although I bought them.

my 2017 would not work without the resistors, I do have an audiocontrol lc7i that my speakers are tapped into then it goes to the amp if that makes any difference I don't know

What head unit do you have and what amps are you running?

 

[appzattak]

I have the stock Uconnect 5 head unit, and I have 2 sundown amps

Ok, now I'm concerned about my planned install. I have the 8.4 non-Alpine system with 6 speakers. I already have some Focal components for the front doors, some AD Audio 6.5's for the rear doors, a 6.5 Digital Designs sub with BBox, a JBL 5 channel amp (model 4505) and a Clarion 7 band EQ.

Now, do I need these resistors too (and wtf are they really)?

 

[appzattak]

yes you will need them, basically they put load on the system so that the head unit sees that the speakers are there, if they're not there the head unit will not see that you have any speakers attached so you put those to create the load
