I need an amp for 2 SA-12s 1 ohm

[Based]

Could I use the FIX86 just for my sub? Or do I have to wire all my speakers to it in order to calibrate it properly? I'm going to upgrade my door speakers in the future but I don't think it's worth the trouble to wire my stock speakers to the DSP if I'm just going to change them in a couple months.

yes for now and then when you had the amp you will use the other channels. Def want to tap all the hi wires and get it done while you're in there. do you have a factory amp you may need this

what car do you have

the dsp has to tap into every speaker

2016 Ford Fiesta ST. I'm unsure if it has a factory amp but it has components so maybe that means it does?

Not necessarily but each speaker needs to be attached to the dsp. After amp or after head unit of no amp

So how come the LC7i has a max output of 8.5 volts but the JL FiX 86 only has a max of 4v on the subwoofer output?

depends on the loc

DSP-88R – Precision Power

has 8v outs

JBL MS-8 car audio system integration processor | eBay

my fav has its own little amp also built in until you upgrade amps, can run at 2 ohm

JBL MS-8 | eBay

really easy auto tune feature with mic

I am looking at the JL Audio FiX 86 and it really looks cool. I just don't want to spend $350 lol.

I am looking at the manual for it and I guess it just takes the signal from the OEM speaker connections and send it to the RCA output for the subwoofer amp? Just like a regular LOC? I don't understand how that would work when you put an amp on your door speakers though because then where does the DSP pull signal from?

Very crude but inline speakers to rca to amp and then back to speakers

so basically you cut the speaker wires behind the radio or after the amp. put them into the dsp. the dsp runs rca's to the amp. then the amp runs speaker wires back to the other end of the cut wires.

Oh ok so I would have to get to the wires coming off my HU. Right now I just have my converter tapped in to the + and - of my passenger side rear speaker. Then plug my amp into the RCA on the converter.

If I don't have an amp for my fronts yet, how do I hook them up to the DSP?

well you can tap for now for just the sub all the speakers but when you install the amp you will have to cut

So how do I get signal to the sub amp? Just put the wires from the right rear speaker into one of the inputs?

no you would have to tap all the speakers to do it correctly its not a basic install like a loc
