[QUOTE="East, post: 8647152, member: 644796"] So just bought a complete kit of (2) SA 15 V3's, Machete Alphard M2000.1, 42hz 7ft^3 box, got it real cheap but it all looked in good condition and the guy had them less than a year. So I brought them home hooked up the Alphard Machete to my 18" BTL and it sounded great, put out lots of power barely got warm... Nice amp is good. So then I drug the 15's out to my car and hooked them upto the amp and it hit pretty **** hard that's until I went to my normal listening volume and then 1 of the subs started to sound like it was bottoming out or hitting the pole piece or something. So I hooked up the other sub alone and it did the same thing but a somewhat higher volume... I took the subs out checked the wiring over and I was at .5 ohm which this amp doesn't support, but the guy who sold them to me had them wired this way the whole time. I messaged him he said he had no issue with them when he sold them and they didnt make any noises. So are my subs fucked or what? Sundown rep said the SA v3's cannot bottom out the most they can do is hit the spider from max excursion. I was playing a high frequency song too and the amp is properly set. Theres no scratching when I push on the subs, coils look good in gap, read good on dmm, dustcap and everything is fully intact, no rips and the subs make the noise outside of box freeair as well. Did I get screwed or is there a simple answer to this? because I've watched multiple videos of SA15 v3's taking 3k daily and I gave them a measly 2k. [/QUOTE]
