Thats just it though, the suggestions I make are just that, suggestions.... from opinion. The OP is obviously not trying to build something for major SPL so wouldn't a DD or a Crescendo kind of be overkill? I agree with you there, Maxxsonics are very hit and miss. I have a HF BRZ1700.1D and it definitely is underpowering my sub, even though the RMS rating is much greater than that of my sub. These are just suggestions and as I have said before, the OP will make the final decision based on the information he finds most useful. But for NOLoud4U to look at me like I have two heads for suggesting a budget route and a more expensive route is just uncalled for. I can honestly say that OFC performs better, depending on the brand. However, a good, TRUE 0ga. length of CCA can carry just as much current as some of the cheap brand OFC, can you agree there? And at a lower price, unless you're pushing 2k RMS, works just as well. I have seen some dumb posts on here but none of the amps I suggested are BAD amps. Crunch are Maxxsonics bottom line amps IMO and rarely put out rated power.
