Overall good. I knew to figure it out all the way I would have to get it hooked up. One catch others may notice. You can’t use eq boost for sub frequencies if you use the sub x over output at the same time. My amp already has this, but if you boost 20 hz @ 18 db and use the sub on the rear out instead then those powerful low signals get sent to the mids and highs. You will need another amp with a high pass x over to stop those deep frequencies.
