You can then make it as loud as your speakers can handle. The unit only puts out about 20 watts RMS. You can try pushing the SLA sliders in audio setup to the max. I found that creates distortion. They'll be no SLA slider for your AM/FM radio. Quote Link to post Share on other sites
kylek567 Posted August 18, 2014 Author Report Share Posted August 18, 2014 I know my car came with an amp. Why would I need to install one? Quote Link to post Share on other sites
douger Posted August 19, 2014 Report Share Posted August 19, 2014 I know my car came with an amp. Why would I need to install one? Apparently yours isn't powerful enough. My Grand Prix came with a Monsoon amp. As near as I can tell it put out about 50 watts RMS per channel. I now have a Pioneer 150 watt per channel RMS amp. Setting 20 is as loud as 40 used to be... without the distortion. Quote Link to post Share on other sites
kylek567 Posted August 19, 2014 Author Report Share Posted August 19, 2014 Could you tell me the model number of the one you have? Quote Link to post Share on other sites
douger Posted August 19, 2014 Report Share Posted August 19, 2014 Could you tell me the model number of the one you have? GM-D8604. My bad on the output. It's only 100 watts RMS per channel at the 4 ohms my speakers are, which I also replaced with Pioneer units. I'm also running a Bazooka bass tube. It's still miles better than the OEM Monsoon amplifier. Quote Link to post Share on other sites

NFrazier Posted September 1, 2014 Report Share Posted September 1, 2014 Are you just saying the AM/FM isn't "loud", or every source? Quote Link to post Share on other sites
kylek567 Posted September 3, 2014 Author Report Share Posted September 3, 2014 Everything. The stock radio is louder, and I am not sure why. Quote Link to post Share on other sites

spastik monkey Posted November 9, 2014 Report Share Posted November 9, 2014 sounds like the stock amplifier was used to line level it, and it got changed to pre-out level during the install. Quote Link to post Share on other sites
