Reddit mentions of Sound Storm Labs S4EQ 4 Band Pre Amp Car Equalizer with Gold Plated Front Rear and Subwoofer Outputs

I run a 4 channel amp so I can use the front two channels for two component style door speakers and then bridge the back two channels together for running one sub. equalizer

I think you could probably spend 150 bucks and be set up pretty nicely. It won’t be competition sound, but you’d be jamming

I'm gonna make a nice write-up for the whole thing now, but to get your gears spinning, here's a quick run-down.

Took out my radio, and fabricated a little frame to mount the tablet behind. HDMI-out from tablet goes to this. That goes into an input on this equalizer. I have a panel-mount 3.5 input that goes into the other input on the EQ. I had a double-din radio, and the tablet and the EQ just perfectly fit in the hole it left. I wired a 4-port 12v car charger receptacle thing, and mounted it behind the dash. this plugs into that, and charges my tablet, and provides a charging USB-port. I'm gonna mount a USB port next to the EQ, there's a bit of space there that needs to be filled. hacked this to use for the power for the HDMI-converter box (Just soldered the connector from the box to the inverter.)

So, audio from tablet to HDMI-box. Hdmi-box audio to EQ. (HDMI video to 3 ports installed under my dash... in case I wanna hook a TV up to the truck? I don't fucking know... I just did it!!!) EQ to amp, amp to speakers. The tablet's charger is connected to a line in the truck that is only hot when the car's turned on, and the tablet is set to turn the screen on when charging, and disable everything (gps, screen, all apps, etc... [wifi after 30 minutes, in case I want to transfer files over my home network]) So... when the truck turns on, the tablet turns on, when the truck turns off, the screen, all radios, and all apps turn off. Should last at least a few days on standby.. if I don't run the truck for a week.. I dono.. i'll figure that out later.

Hope this wasn't too confusing... ask me if you wanna know anything else.

Oh, I learned how to do everything from the internet. I've never done any car stereo work before, or anything like this at all.

For looks, you've gotta mount it in the dash, but mounting it isn't an unreasonable option. If you go the HDMI route, make sure your screen still rotates with hdmi plugged in... Had everything installed and ready, plugged in the HDMI cable... everything's upside down.. no way to fix it... gotta cut the dash apart even more now...

So something like this but for home use?

ssl equalizer and pre amp

It’s not the best quality so half a years use out of it might explain the issue, but it’s the right size and has the features I want

what you want is an equalizer, but i can't tell you which one specifically because i'm still a bit fuzzy on how your stereo is hooked up
but look at this for example
