I bought this unit to install in my 1985 Goldwing Aspencade motorcycle so I didn’t want to spend much and my expectations weren’t high. Since the bike is put away for the winter I installed it in my Nissan Frontier. Installation was easy and everything functions as advertised. Sound quality is better, especially on the low end, than the OEM H/U it replaced primarily because this unit puts out more power to the speakers which are OEM. I have connected the low level (RCA) outputs to a 10 year old Infinity Basslink and the combined system sounds good. Yesterday I installed a Bluetooth receiver through the Aux connection to complete my system and I am pleased with the results. This is a very versitile H/U and while I have only had it a week its seems to be well made. I am considering leaving this installed in my truck and buying another one for my bike. All said and done I’m satisfied with this purchase and for the $32 + shipping spent you can’t go wrong.
