ecpiii Posted September 24, 2009 Report Share Posted September 24, 2009 Hey guys. I just bought a 2008 Toyota Sequoia with the JBL Synthesis system. My installer used a TYTO Metra harness to integrate into the factory amp. For some reason, the front speakers seem to be cutting out, or losing the high end signal. Sounds like the volume shifts. I have seen that PAC Audio recommends a 4V input, and the F900 only provides 2V. Is this the culprit? Should I switch to PAC Audio? RCA in line boosters created REALLY bad alternator noise, so boosting the signal is out. Any ideas?? Quote Link to post Share on other sites
1loudls Posted September 24, 2009 Report Share Posted September 24, 2009 a weaker signal should have nothing to do with the sound cutting out, it sounds more like a bad connection or a bad interface, i would start with checking the install to make sure that there isnt a problem there like a loose wire, if that checks out i would try a different module or a different brand module like the scosche TA07SR Quote Link to post Share on other sites
ecpiii Posted September 24, 2009 Author Report Share Posted September 24, 2009 I think the Scosche is the next step, and then the PAC. Wiring all seems to be good, since I am just using the RCA outs from the F900. It even does it when I use the bluetooth on the F900. Go figure. Quote Link to post Share on other sites
