gottahavbass917 Posted August 23, 2010 Report Share Posted August 23, 2010 I currently have 2 12in W7 and i wanted to use another amp(s) other than JL's amps. My question is can i use other amps when these subs are single 3ohm and when wired up would be 1.5ohms. Please help me figuring out what amps would work for these subs for 1.5ohms between 1500-2000 rms. thanks, John Sorry if a question like this has already been asked.

Boon Posted August 23, 2010 Report Share Posted August 23, 2010 I'm thinking a Sundown SAZ-2000D would be right on the money. Quote 10.x volts fo' life! Link to comment Share on other sites More sharing options...
hdorre Posted August 23, 2010 Report Share Posted August 23, 2010 Look for amps that put out 2000 watts at 2 ohms Quote On 5/8/2011 at 7:38 PM, Kranny said: On 5/8/2011 at 7:35 PM, 'Maxim' said: It hurts me inside when I read stuff like this and remember you're 15 LMFAO so true Mitsubishi 3000GT (Old Build) Headunit: Pioneer 80PRS Frontstage: (2) McLaren Audio MLT-2 Tweeters & (4) PRV Audio MR Series Neo 6.5" Mids Substage: 4 15" Hybrid Subs - Tantric Motors & Sundown Softies Amps: Banda 2.4D Amp (Tweets), American Bass VFL 350.4 (Mids), and (2) Ampere 3800s Electrical :Singer 260A Alt & JY Power Lithium 2005 Chevy Colorado Ext Cab Headunit: Pioneer 80PRS Frontstage: 4 PRV 700Ti Tweets & 6 10" Delta Mids on 3000wrms Substage: 6 Fi BTL 18s in a 4th Order Walkthrough on 3 Wolfram 4500s Electrical: Singer "390" and JY Power My Official Feedback Thread Link to comment Share on other sites More sharing options...
gottahavbass917 Posted August 23, 2010 Author Report Share Posted August 23, 2010 Thank you for responding does it really matter that the sub and amp would be at different ohms cuz i dont want to blow my subs or any amp that i buy. Quote Link to comment Share on other sites More sharing options...
gottahavbass917 Posted August 24, 2010 Author Report Share Posted August 24, 2010 can someone help explain to me why i could use two different ohms for subs and amp? John Quote Link to comment Share on other sites More sharing options...
hdorre Posted August 24, 2010 Report Share Posted August 24, 2010 Say you wire a dual 2 ohm sub in parallel so its now a single 1 ohm sub. When you plug it into your amp, thereafter something called impedance rise. At some frequencies, the amp recognizes the sub as a 1.3 ohm sub and put out power accordingly.

Thanks i didnt know that so when most people say there wired down to one ohm there probably not at one ohm and not pushing there amp to full power? And how can you offset this in future set ups Quote Link to comment Share on other sites More sharing options...

And how can you offset this in future set ups Exactly, they arent getting full power. Are you asking how to get full power from your amp? Many people wire their subs at .5 ohm. Therefore, the amp sees about 1 ohm after rise Quote On 5/8/2011 at 7:38 PM, Kranny said: On 5/8/2011 at 7:35 PM, 'Maxim' said: It hurts me inside when I read stuff like this and remember you're 15 LMFAO so true Mitsubishi 3000GT (Old Build) Headunit: Pioneer 80PRS Frontstage: (2) McLaren Audio MLT-2 Tweeters & (4) PRV Audio MR Series Neo 6.5" Mids Substage: 4 15" Hybrid Subs - Tantric Motors & Sundown Softies Amps: Banda 2.4D Amp (Tweets), American Bass VFL 350.4 (Mids), and (2) Ampere 3800s Electrical :Singer 260A Alt & JY Power Lithium 2005 Chevy Colorado Ext Cab Headunit: Pioneer 80PRS Frontstage: 4 PRV 700Ti Tweets & 6 10" Delta Mids on 3000wrms Substage: 6 Fi BTL 18s in a 4th Order Walkthrough on 3 Wolfram 4500s Electrical: Singer "390" and JY Power My Official Feedback Thread Link to comment Share on other sites More sharing options...
