Amp wiring
Hello everyone, so I installed my amp and sub the yesterday and would really like to know if I did this correctly, or if there is a more efficient way.
By the way this is my first sub in 13 yrs and first install myself. I just don't understand car audio much.
Can you tell me if I hooked up the amp speaker correctly or if there is a better way?

If I understand the somewhat cryptic markings on the amp, it looks like you are running one (of four) channels
to the sub, delivering a whopping 37.5 watts to the sub. If you move the blue wire to the left to the ChB -R
position, you'll bridge the rear channels, quadrupling the output to 150 watts.
That said, that's probably not the best amp to use to power a sub as even bridging the rear channels still
means you are only using 1/2 the amp - it's really designed for powering 2-4 speakers. You could use the
front channels to power your door speakers too, which should be a nice improvement if you are just using the
headunit's internal amp.

First off, thanks for the reply. I will change the blue wire and let you know how it goes.
Yes, my front speakers and tweeters are ran by the head units internal amp.
Question: So in order to run the amp to the other speakers. I do the same as running the sub. RCA cables to head unit and wires from amp to speakers.
Would the RCA cables go in the output section? or would it go to channel A? For my RCA plugs I have CH A, CH B, and OUTPUT.

If you don't have a copy of the amp's manual, here's a link.
Basically you'll want to wire things as described in the "three-channel" section.
Exactly how you will do it depends a bit on your headunit - how many RCA outs your headunit has (some only have two), but
yes, in general, you'd add a second pair of RCAs to channel A on the amp, and then speaker wires running from the amp
either directly into the doors, or spliced into your headunit's adapter harness to use the stock door wiring.

Thank you! That's what I figured, I guess I was just hoping on an easier route. By just running RCA's from the OUTPUT side of the amp to the head unit.
Anyways, thanks again!!
Here is some pictures of my setup so far, pretty simple.

The "output" RCA jacks on the amp are to send the preamp signal to another amp, for instance a dedicated
subwoofer amp.
You could get away without running a second set of RCA's to the amp by using the 2-channel switch on the amp
to send the same signal to both A and B from the RCA's in A. You'd give up the ability to independently
adjust the subwoofer volume from the headunit, and you'd still need to run the speaker wires.
