[QUOTE="09Alti, post: 5962042, member: 606244"] Ok guys I need some help. Sorry if I sound like a newb, but I kinda am. I have 2 Kicker CVR 12 D4s and had them running off of a Kicker SX900.2 and had pretty decent sound for what the equipment is. I recently traded my amp for a new one (I won't say what brand it is yet) that is rated at 1500 @ 1. The subs are wired at 1 ohm. When I first hooked up the new amp, I didn't have hardly any sound, so I played around with it some, unmounted the subs and checked my connections etc, and it started working (not sure what I did to make them work, it just worked). So I went out into an empty parking lot to tune the settings and junk and had it sounding ok so I left the lot. On the way home it quit working again. I checked everything again, put it all back exactly how I had it, and it worked again. They worked for about a day and a half and yesterday it quit again. So tonight I pulled the subs out of the box again and checked the resistance of each coil with a DMM. All 4 coils read exactly 4.5 ohms, so I would assume that these are ok since they're dual 4s right? I checked the voltage coming from the speaker terminals to the subs on the amp and only see 0.05v. I checked my power wire voltage at the same settings on the DMM and it read 12.5v (car off, radio on and volume at 3/4 volume) I would figure that the voltage coming from the amp should be higher then .05v right? Another funny thing that I noticed is that with the sub hooked up, I checked the resistance on coil 1 (the one wired to the terminal cup on the box) and get anywhere from 19.x ohms to 22.x ohms, is this normal? I have the gain at near full and never changed it before/after getting any of the readings from the DMM. So are these normal readings I should be seeing from the amp? Or what am I doing wrong? Sorry for the novel but I wanted to give as much info as possible. I can say the name of the amp if needed but I'm afraid there may be some bias on the answer I get if I say the name. Thank you in advance for any help I can get here, as I am out of answers. Jeff [/QUOTE]
