Adding an amp with factory amp'd system

[BoomZoom808]

Take the LOC and connect it to the rear 2 speakers full range then run that in to your hifonics 2000.4 use the RCA line output of the 2000.4 to connect rca input for your sub amp its not that complicated. Take a look at my build log I did the same thing you are trying to do except I don't have a LOC anymore I used a JL 500/1 which can do the same thing as a loc. All you need is an amp that can pass-thru a FULL RANGE SIGNAL to another amp it doesn't matter which one is first. You don't need to buy anything else.

You have to tap in to left and right for full range stereo and the shop should have done it too.

get another hi/low adaptor . wire both in either behind the radio or at the factory amp one front one rear. then run both rcas to the 4ch and run the rca pass through to the bass amp or run the front rca to the 4 ch and flip the switch on it to 2ch mode and run the rear rca to the bass amp..

so i have an older silver looking "?axxess" ? model lino out converter i used in my old car might be able to use that

[jmsonoma03]

You also need to know the dash speakers only play high freq and the doors only play mid freq. The factory amp does the cross over for them. The rear speakers are full range. If you tap in to the front speakers after the factory amp you are not going to get a full range signal. This is why I say use the rear factory speakers because it is full range signal and you can do anything you want with it using the aftermarket amps x-over section. If you tap in to the front dash or door you are limited to whatever frequency range is set by the factory amp on that specific channel. This should be the break down below unless you also have a factory sub.

1+2 dash/high freq

3+4 doors/mid freq

5+6 rear/fullrange
