Hooking up a system

Hey autotech796 I have a 2014 fusion SE  with the  navagation and touch screen in it , i was wanting to add a sub , amp , and possible putting a couple 6by9s in the back deck but i dont realy want to change the head unit out because i dont want to mess up whats already there plus the wiring harnes is like 250 bucks for this car . I figured I would have to run the power cable through a togle switch so I could power everything on and off and run a capacitor so I dont kill my battery . What would be the best way I could hook this up . Thank for your input .

Re: Hooking up a system

As far as the 6x9's in the back you would be looking at the cost of speakers plus installation $64.99 and a speaker harness if available.  The remote wire that will be run to a switched 12+ source is what will turn the amp on and off so no need to run to a toggle, especially the power wire.  4AWG is not something that you are going to want to toggle or mess with.  You can definately keep the factory radio for your vehicle as it would be more cost effective to keep the features that you have already become used to, so just add on the amp and subwoofer/s.  Below is a reply from another thread of mine that I just created a couple days ago, but it is going to be spot on to your situation also.

 

I can provide you with the necessary parts for the installation, but unfortunately there are way to many options out there without your input for me to post up.  I would recommend speaking with a salesperson in-store, or an Autotech for a better list of options for the setup that you are wanting, with the descriptions of the "sound" that you are after.

 

With that said, you will need some basic parts and since you are wanting 2 subwoofers you will probably need a minimum of 4AWG wire, along with the equipment to play from the OEM (stock) radio.  Below is the breakdown of this:

 

Materials charge $5.00

Amp install $99.99

Line output convertor $14.99

LOC Install $24.99

4AWG Amp Kit $109.99-$149.99

Dual Subwoofer Installation $39.99 (this is only charged if the subwoofers need to be mounted into the box)

(Single subwoofer mount $19.99)

TOTAL BEFORE AMP,SUBS, BOX, AND SALES TAX W/$149.99 AMP KIT: $334.95

 

Those are the basics of what you would be looking at to get this setup installed.  There are tons of options that you may find come packaged with our installation, and also part of the reason why I would hope you can visit the store to see if we can't save you some extra $$.  There have been other threads under the Car, Marine, and GPS where I have replied to those customers with the information that they have provided.  Perhaps browsing around there can start your search in the right direction, and if there is any question along your journey, please do not hesitate to let me or your local Autotech know!

 

Thank you for all the time that you took to join and write with the community, and I hope you are able to get that "bump" that you are wanting here in the very near future! Best of luck!

Another link I would recommend checking out for more clarifications would be this one HERE!  If you are still in need of anything further or need more clarifications do not hesitate to let me know!

Re: Hooking up a system

I was reading on another page could you guys still hook up something like this

Audison’s bitTenD Processor so i could control the levels of everything a little more than the factory hu . But i was wanting to run some kind of toggle switch so i could turn the subs on and off and still use the basic sound controls like i have now in the car for when my wife and kids are riding with me because she dont like it as much as me or have it on all time . But i was figuring that a single 8 or 10 inch Xv.2 series sundown audio sub would be enough for what im looking for , and another quiestion since the 10in has a 1500 watt peak rms power there 750 4 ch amp bridged would be enough for everything and not hurt the sub wouldnt it .

Re: Hooking up a system

The sundown 10" subwoofer that you mentioned is 600W RMS so finding an amplifier that is the same RMS value not Peak would be your ticket.  There are tons of amplifiers out there to use for a subwoofer, but I could never recommend a 4 channel amp for subwoofers, even bridged.  You are going to want to find an amplifier that you do not have to bridge, since bridging an amplifier will quadurple the work that your power supply would have to handle since you are halving your impedence.  Basically most 4 channels are A, B, or AB hybrids that would need 2 channels combined to get you the same amout of power that a D class amplifier would supply from a single mono block amp.  Mono D class would be what I would personally recommend around 600W RMS. 

 

We could definately install that processor so that you could control the levels a bit more, but there would be alot of other possibilities that you would have to factor in for your tuning.  The Line Output Convertor would have to connect to a pair of speakers and the LOC has its own tuning that would need to be completed, but could really distort and make that processor not really effective.  It is about the source of the supply, and when you connect to factory equipment it really doesn't allow you that flexibility that you control the levels that the processor provides you.  I think it is great that you want to install a processor and they really do help out, but with aftermarket equipment where there are outputs strictly designated per specific frequencies and output voltages.

 

We can also install a toggle switch on the remote wire that would be able to turn your subs on and off, but a bass knob would be another recommendation that I would install.  I try not to mess with currents that are flowing to the amplifier as much as possible, and the bass knob would allow you to turn the subwoofers on or off in the same way that you are thinking of a toggle switch, but you aren't messing with DC current. 

 

All in all I think you have a good understanding of what you are wanting, and if you want the sundown audio subwoofer, all you would need to do is install a mono block amplifier *(D class if possible) that will allow for 600W RMS (do not look at peak just look at the continuous or RMS values). 

 

Before you get all set it would be greatly beneficial for you to stop in and speak with your local Autotech.  This way you can get installation dates and also more information for the installer that would be completing the installation.
