Right now I have a Skar TXL 10 being pushed by a Skar SK 1500 at .5 ohms. It under my back seat in a 01 Silverado. I barley use my back seat so I'm going to sacrifice it and put 2 15s in separate boxes. If I need my seat I'll take the 15s out and put the 10 back in. My questions are can I run 2 15s at .5 ohms with this amp until I can find another one to buy. Everyone is out of stock. Im sure the amp will be working alot harder than the ten its pushing now. When I do find one I'll use one amp to one sub and run them at 1ohm. Next question is what sub's. I plan on putting them in around 3.5- 4.0 cu ft each. I'm seriously considering Soundqubed hdc3s. I have been reading good things about them. I feel they will play decent with one amp until I can find another one and the price cant be beat. Any input would be appreciated. Thx
