[QUOTE="mrpep, post: 8658035, member: 661076"] I have a Yukon 2003 that has 3 rows so space is tight between the 3rd row and the hatch rear door. I have no big three upgrade. I am using 4 Gage OFC from the battery to the fuse and CCA Gage from that point to a secondary battery that runs in parallel, the cca to amp. I run short grounds of CCA 4Gage from the battery to a threaded seat post that has had the zinc cleaned off so it is all metal to metal contact. I use a Alpine mrx1000 so 1000 rms monoblock to power a W6V3 and I have just bought a used W7 10" in a ported box. My concern is that I am not getting enough power but the the W7, it is rated at 750 rms. Should this system do for what I need? I have heard of Head units clipping , how do I know if mine is ? Am I getting enough power to the sub? I did hear some clipping when I was trying to tune my amp/ gain so I feel enough power did make it to sub but want to get your thoughts on this. Im just tryint to make sure that I am not bottlenecking or losing power. [/QUOTE]
