I have a couple speakers that sound OK when the volume is low, when you turn them up, they pop or crack once in a while. Are they blown? Not enough watts or wired wrong? nor sure what's going on. Need help please and thank you
check the wattage of your speakers and the amp. If you are running a 100w amp and 50w speakers, they will sound all distorted as you turn the amp up and you will blow them. Ride command has it's own amp (albeit a separate hardware behind the interface), but if you say use the same speakers from the stock system, it will sound like crap, but OK at very low volumes as the amp is twice the wattage as the stock system.
All the other stuff above is all good LOL. Not sure what stock setup you have, sounds like the base model and not ride command. The rear speaker out is for base signal, so I would recommend going with clipping into the high output wires and reducing the signal (unless the amps take high output that is). I use the "Scosche LOC80" to reduce the signal. I don't stock them though as they are a bit temperamental. Once you get one that works, it's good, but a common problem. Just easier to let another company handle it LOL. Wiring harnesses we do, but mostly are around ride command and haven't converted the stock stereo yet to a plug and play setup. Could probably provide something, but would have to take a look and see what adapters I need.
