akrja_07 Posted April 17, 2011 Report Share Posted April 17, 2011 I bought some subs used that are supposed to be level 3 with level 4 coils, meaning they can handle up to 1000 RMS, but how can I tell if the subs actually have this upgrade or not? I don't really want to go throwing 8 or 900 watts to them and fry them because they actually have the level 3 coils. Anyways, how can I tell? I don't think the person I bought them from got me but want to be sure before spending $200+ for a new amp... Thanks!!!

iKidwell Posted April 17, 2011 Report Share Posted April 17, 2011 throwing 800-900 watts at them won't blow a level 3 if it's clean power..i had mine on about 1200w each for a while Quote c'mon now, if i was shooting an 8 year old, it wouldnt be MY 8 year old. i recently got a Pyle PL1590BL and i was building an enclosure for it tuned to 25 hz. i didn't have any tools to cut a circle so i hit it with a big hammer. 2003 Infiniti G35 Sport Sedan Build in Progress Link to comment Share on other sites More sharing options...
akrja_07 Posted April 17, 2011 Author Report Share Posted April 17, 2011 Are there any serial numbers on the sub? I did not look before putting them in the box, will look if need be but would REALLY prefer not to take the subs out of the box. What ohm are they? Dual 1 ohm, I have them both wired to a 1.3 ohm load. throwing 800-900 watts at them won't blow a level 3 if it's clean power..i had mine on about 1200w each for a while Ok, thanks man!

The A Team Posted April 18, 2011 Report Share Posted April 18, 2011 If they are d1 coils for sure lv4. I have had stock lv3 12s on a Stetsom 4k2d and a customer with lv3 12s on a DC 3000.1 both setups slammed! Quote Link to comment Share on other sites More sharing options...
cthedinger Posted April 18, 2011 Report Share Posted April 18, 2011 Just because they are LVL 4 coils does not mean they automatically get the RMS rating of a LVL 4. It just means they can take a little more power than a regular LVL 3 coil. Quote If you have any questions PM me or Add me on Facebook CLICK ME!
