    I have been toying around with the idea of putting a separate 2 channel amp in with my Kappa 5 to power the front dash speakers only, leaving the Kappa to power the Hertz Components on the doors and the sub. I found this "little" JBL amp on Amazon for just about $50 and thought it would be worth the time, effort and cash to give it a try. Holy Crap! This did so much more for the system that I could have imagined. Every genre I listen to hit so much better now - the song that tested the system the most was Dimension by Wolfmother and it was amazing. Tried some Lenny Kravitz to see how well it was with heavy bass and distortion and I was just blown away.

    So what I did was get a RCA splitters to split the Front Audio signal from the DSR1 so I have basically the same signal going to both amps for the front speakers. Got a Distribution block for the power run from battery, distributed to both amps on 4 gauge. Ran a new ground, also 4 gauge. Refashioned the amp rack I got from @tech12volts so the heater ducting has more clearance and made my own rack for the JBL. DSR1 is taped with a Gorilla dual sided tape to the center console. I need to get something to cover the Kappa 5 amp from the back of the passenger seat so it is less visible, but all of this still fit under the passenger to my general satisfaction.

    Since I only wanted the dash speakers to fill space on the sound stage and not have the same gain as the Hertz speakers, the JBL amp's gain is all the way down. Otherwise, I left the Kappa 5 and the system alone. The audio to the doors is stronger and fuller, the dash speakers are not getting overpowered. I haven't even finished setting up the EQ on the app yet. Can wait to see how much better it gets.

    For the record...there is no such thing as overkill. Just different degrees of awesomeness! Nicely done!

    Overkilled it man. That's the way to go. Kappa 5 is on my wish list. What speakers do you have? Im thinking about the 60 csx and adding the 2“ mid upgrade.

    Very nicely done @Bigolbaddy ! Was planning on doing exactly what you did, same amp and everything, but wife put the kibosh on it. That 2ch is a lot bigger than it seems in the Amazon pictures. One question though, any advantage over splitting the front vs setting up the dsr1 to have dash,front, rear sub? Or do you dash speakers have bass blockers built in? Any advice is appreciated! Very nice

    I didn’t split the front at first. I tried using the Spare RCAs, but they had no audio passing through. I figured it had to be because the JBL system is set up from Factory as Front, Read and Sub, that’s it. So to use the HU and the wires as is, I don’t think that the DSR will pass a signal through the Spare RCAs. Just my thought.

    OP, Im guessing you are using one channel for the front left and one for the front right, correct? Does the dash tweeter signal comes from the door? Where do you listen to the voice commands and phone calls?

    From what I understand the center speaker signal is pulled from the left and tight channels. I can’t say that 100%, but I read that here for what’s it worth. And yes, one channel to the left and one to the right. On the TO3 it’s the front left tweeter and front right tweeter.
