oldsoundguy Posted June 7, 2014 Report Posted June 7, 2014 Do some more reading on the subject of setting gains. After that and only after that come back and let us know why you blew your sub. 80prs Arc Audio Xdi 1200.6 (using active crossovers) Freaking awesome amplifier Incriminator IA 10.1 Focal PS 130v 5.25 (doors) 4" Faital pro Neo (kick panels) 3" Faital pro Neo and focal tweets( dash) DC Audio level 3 12" custom box designed by joex built by me AGM front, XS 750SE batteries rear DC 180 alt 99 Toyota Tacoma extra cab http://www.stevemeadedesigns.com/board/topic/179476-my-small-build-turned-into-the-ongoing-build/
Rck'nRF Posted June 7, 2014 Author Report Posted June 7, 2014 What was this post about again? It's just reading material for one waiting to board their plane..
bbeljefe Posted June 7, 2014 Report Posted June 7, 2014 My HU is a pioneer 45wattx4(15wx4 RMS) and when i had my Rockford gain ANYWHERE UNDER 3/4 it was ABSOLUTLY unacceptable! as for producing bass, No matter where i adjusted bass/settings on headunit,amp/X-over,there was NO cab filling bass a 15" should be doing. This is the 1st sub i ever burned out ,and if my gain was to high then i'm "glad i cooked it" .. Pioneer makes a lot of different head units and the internal amp has nothing to do with the preamp voltage. If your head unit has a 4 volt preamp the gain was set way too high and if it has a 2 volt preamp, it was still too high. The gain knob is not supposed to make up for a lack of power, a poorly constructed box or a cheap sub. It's there to match the signal strenth from the preamp to the sensitivity of the amplifier. Nothing more and nothing less. Facebook: facebook.com/audioanarchyllc Instagram: audioanarchyllc Youtube: youtube.com/bbeljefe
Rck'nRF Posted June 7, 2014 Author Report Posted June 7, 2014 I think a smallish sealed box (1.5cuft)really aided in a nicely cooked coil also, I do know this one is going ported from hence forth,i have a new respect for moving/cooling air.. i know i have the ears of a bat when it comes to how music should sound,and where i had my gain was perfect,if a sine wave killed it,good riddance,but i sure did love the look of the "S" Alpine series!
Ahmed Johnson Posted June 7, 2014 Report Posted June 7, 2014 With a smaller sealed box you should be able to put a little more power to them than a large ported box. Bro-ski, it's your fault man. Plus 1.5 cu ft. is a bit big for an alpine type s.
Rck'nRF Posted June 7, 2014 Author Report Posted June 7, 2014 Well,today i am throwing in my 2Ohm "S" alpine 15" into the same box,going to adjust this previously & heavily used sub to my ear again..will post conclusions&results for you in the weeks to come for the exciting results! (burned out sub was 4Ohm'r)

CleanSierra Posted June 7, 2014 Report Posted June 7, 2014 Box volume had nothing to do with what a voice coil can handle thermally. Your ear cannot hear a square wave, period. You set your gain by ear, that's the likely reason the coil likely gave up. It probably died from an improperly set gain, nothing more, nothing less. The other possibility is that the sub had a defect from the factory and went prematurely. There are literally thousands of Type S setups around the world that likely have gains set the same way yours was, as are still alive today. Im not the one you want to try to troll. Just a fyi for you.
CleanSierra Posted June 7, 2014 Report Posted June 7, 2014 Your box had nothing to do with the failure. Im not the one you want to try to troll. Just a fyi for you.
