Audison SRx 5 540W Five Channel Power Amplifier with Crossover 50W x 4 (4 ohms) + 300W x 1 (2ohms) 70W x 4 (2 ohms) + 260W x 1 (2 ohms) 140W x 2 (4 ohms) + 260W x 1 (2 ohms) This amp can also be used in a bridge from what I have read. Here is the manual if you need more information. {url removed} The box is different than the default sizes given in this app. 22.5”x11.5”x 5”. The box weighs about 10-15lbs without any extra packing. I will have to place this in a bigger box to protect the item during shipping. If you need this shipped it is located at 98126 and you will need to go to UPS or USPS for an estimate. Then you will have to pay for shipping since this application screwed up shipping. I am open for pick up if you’re in the Seattle area. PLEASE SPARE ME THE CASH APP SCAMS. YOU’RE JUST WASTING EVERYONE’S TIME INCLUDING YOUR OWN.
