Hey guys. Ok I just hooked up my sound system and I'm not getting any bass. I have my factory HU and used a line out converter for my RCA hook ups.

I double check all my connections and everything checked out.

I have 2 12" Rockford Fosgate P3D4 subs and theAR3000.2 BOSS Amp.

Is there something I'm missing as to why I can't get any bass through my Subs?

I tapped into my factory radio harness. I have a 09 ford fusion with the touch screen head unit. My amp comes on with the green LED showing. I did the AA battery test on my speakers and they are fine. Is it my line out converter that isn't right? Thank you. I will post pics in a little while

What wires from the HU did you use?

I tapped into the 12+ volt positive, 12+ volt accessory, radio ground, right and left rear speakers. I finally got the subs to produce bass but they were phasing so I unhooked one RCA and only one sub worked but produced a lot of bass. I had that happen once before but can't remember what I did to fix it

Why tap into 2 oem speakers? Doesnt the LOC only need one channel ?  Most LOCs are turds and very hard to get to work worth a shit.  There may be a "gain" type adjustment pot on the LOC also.... what LOC is it ?

I have the PAC lp7-2. I needed to tap into the speakers for sound. My other connections were for power and ground only. I spliced the RCA hook ups on the LOC for my rear speakers. It's a 2 channel LOC and yes it has the gain I turned it 2 volts which is what it needed. Just gotta figure out why only one of my CRA hook ups work to produce bass instead of both which put my subs out of phase
