chesthertZ Posted December 30, 2007 Report Share Posted December 30, 2007 i made this topic so i dont have to keep makin new topics to ask questions, any1 should post on it if they have random questions instead of starting new topic. anyway most of u bass experts will prob laugh at me but wats the difference between the OHMS like how do u make your sub 2 and 4 ohms, and wats the difference between them, sorry 4 the stupid question but better to learn of the pros then to not learn at all Quote 1 12 inch infinity 1240watts...only can fit that in a hilux single cab... 1 infinity 1000 watt mono block... 2 Hifonics Zues 6.5" Components 2 Hifonics Zues Tweeters 2 cross-over boxes 1 run of 4GA 200 Fuse 1 Kenwood Head-deck Link to comment Share on other sites More sharing options...
mrwigglezdj Posted December 30, 2007 Report Share Posted December 30, 2007 well you subs come in many diffe ways. and there refering to the voice coil and what each pair of terminals = to like sub one is a single 4 ohm sub, with only one set of terminals, then you have sub 2 which has dual 4 ohm coils, with 2 sets of speaker terminals sub 3 dual 2 ohm which has dual 2ohm coils with still 2 sets of terminals, the ohm load has more to do with the amp you will be useing than anything else, for example you have a poweracoustik 1000D thats only stable to 2 ohms, sub 1 will work on this amp because its single 4 ohms, so the amp will be pushing a 4 ohm load which its safe at sub 2 has dual 4 ohm coils so you can wire it to be 8 ohm or 2 ohms, which the amp is stable at both ohms but you will get very little power at 8 ohms and you will get as much power as possible out of the amp at 2 ohms. sub 3 is dual 2 ohm so you can wire it to 4 ohm or 1 ohm, the amp can power it at 4 ohms but you will possibly damage the amp at 1 ohm since it is not stable at 1ohm load and another good thing about multible coil configs, is if youre going to run more than 1 or 2 you can get the proper coil conifg to allow you to wire up the subs to the amps at the lowest safest load for the amp without damage to the amp Quote Americas loudest work van2006 iasca heavyweight bassboxing champion at 150.4 db with 60second average TL8 memphis PR15s,12 memphis PR6.5's coax,4 memphis PR 1inch tweets Link to comment Share on other sites More sharing options...
unknownuser200985 Posted December 30, 2007 Report Share Posted December 30, 2007 you have to also consider ohm rise plays a key factor in how much power your subwoofer will receive. Also thermal handling goes down with lower ohm loads as well as efficient but it is much cheaper and easier to run at a 1 ohm load which why you notice him home theater you will see mostly 8 and 16 ohm interfaces for cleaner more efficient more idiot proof setups but will also bring prices way up. This is a very large category and you may just want to ask more specific questions. also this might help http://www.forum.realmofexcursion.com/showthread.php?t=4388 Quote Link to comment Share on other sites More sharing options...
chesthertZ Posted December 31, 2007 Author Report Share Posted December 31, 2007 :o lost me on the 1st sentence ahahah, dw bout tryin 2 explain it, thought it would be more simple then that, thats why i asked, i will learn in time... hopefully Quote 1 12 inch infinity 1240watts...only can fit that in a hilux single cab... 1 infinity 1000 watt mono block... 2 Hifonics Zues 6.5" Components 2 Hifonics Zues Tweeters 2 cross-over boxes 1 run of 4GA 200 Fuse 1 Kenwood Head-deck Link to comment Share on other sites More sharing options...
BASS14 Posted December 31, 2007 Report Share Posted December 31, 2007 ok so i have been tryin to get some pics of my system on here just to c wat you guys think and i cant figure out how to get the pics on here?? so that is the ? how the hell do you get the pics on here? thanks!

andym85 Posted December 31, 2007 Report Share Posted December 31, 2007 :o lost me on the 1st sentence ahahah, dw bout tryin 2 explain it, thought it would be more simple then that, thats why i asked, i will learn in time... hopefully its all about series and parallel wiring with dual voice coil subs i.e. one sub, dual 4 ohm voice coils series wiring: negative of coil 1 wired to positive of coil 2...postive of coil 1 wired to the negative of coil 2....this will give you an 8ohm load parallel wiring: negative of coil 1 wired to the negative of coil 2....positive of coil 1 wired to the positive of coil 2....this will give you a 2 ohm load as u can see, and putting it as 'dumbed down' as possible...series wiring doubles impedance, parallel wired halves impedance.... another example: 2 subs, each 4 ohm dual voice coil (like my SE's) you can do parallel wiring on each sub which will put each sub at 2 ohms then you can either wire one subs positive to the other's positive (parallel wiring) and have a final load of 1 ohm (thats how mine are wired) or you can wire one subs postive to the others negative and vica versa (series wiring) and have a final load of 4 ohms any clearer?

fl905e Posted December 31, 2007 Report Share Posted December 31, 2007 i know this is a really dumb question but i always wondered can you build a box out of metal if not then why Quote no system for me yet dont drink my all my vodka or your gonna pay by the gulp Link to comment Share on other sites More sharing options...
andym85 Posted December 31, 2007 Report Share Posted December 31, 2007 i guess u could...it would probably sound like shit from all of the resonance coming off the metal...i mean people sometimes build steal frames around their enclosures, but that is on the outside...and usually only done with major competitors in the higher classes..

BigPimpin91 Posted December 31, 2007 Report Share Posted December 31, 2007 My guess as to why not to build boxes out of metal are; Weight. Sound Quality. Cost. Not easy to tune by changing port length, which basically comes down to cost anyway. Wood is easier to craft. Don't need a CNC machine to make your box. I think there are other reasons but those are the main ones. Quote BigPimpin91's Banging Music Link to comment Share on other sites More sharing options...
