[QUOTE="Rainy, post: 8704441, member: 679644"] First sorry for the noob thread. [B]Hi everyone. I'm new to these forums, and I'm having an issue with my current vehicles audio setup. My car audio knowledge is pretty much enough to wire and hook up a full system (head unit, subs, amp, speaker amp ect). I never measured with an Oscope or even multimeter before now which I'm sure was mistake number 1.[/B] So I normally wire my own systems but didnt have the time with work on this vehicle. It's a 2005 Infiniti G35 coupe, factory BOSE system, bose amp. I had a shop wire it up to keep the bose head unit and add a sub. I noticed immediately they only tapped into one side for a signal, because when I would change the balance L/R, the sub would only be producing sound with the head unit at normal, or all the way to the right balance. Not sure if that is acceptable or if that would cause a problem in and of itself? Anyhow the real issue I'm having now is this - I got a great deal on a Hifonics BE2500.1D 2500w rms amp. Way more power than I needed but hey, the price was right. So I hooked it up to the sub, a 12 inch Alpine Type R SWR-12D2 (1000w rms rated, 2ohm). Ran it for 30 minutes and it blew, smoking. Gain was maybe 2/3 of the way up, Bass eq is at 0, low pass at 80, sub sonic at 20. Was the gain simply too high or could there be another issue? This is the second sub that has blown in less than 3 weeks with this amp. My electrical seems to be great, I get no dimming no surge, no worries. Next sub I will be at least measuring with a multimeter the gains but I'm just having a hard time believing that Type R would roast in 30 min under moderate power/volume listening. [/QUOTE]
