Boost voltage

[Bass so loud it HZ]

Anyone know how I can boost my voltageup a little. I have a 320a auto tech . With a quik start adjustable external voltage regulator . It only goes up to around 15v .my vehicle is 04 jeep so it's controlled by pcm. Wondering if there's a way to boost my regulator up a little more.

I have the same alt just get a 50k adjustable trim pot and wire it in with the voltage since wire on the alternator so that you can dial it in. Or if your vehicle has a battery temperature sensor like my Dakota had which tells the PCM if the battery is cold or hot so that the alternator doesn't overcharge the battery so what I did because my sensor needed to be replaced I instead just cut the sensor off and wired the trim pot to that and I was able to adjust my voltage from 13.2v to 15v

I tried to find a sense wire on mine and couldn't. Maybe I'm missing something .I'll see if it has a temp sensor .I'm trying to get up to around 16vs tho
