no its not. anyone have a nice sub to run this type of test?

usually custom subs surface from parts laying around to make a sub. any reason why you want to build one? there are tons of subs to do do what you want it to do in market now.

its just about suspension. progressive spiders have different tolerance at different points. if you beat the hell out of it out the box the weakest point of the spider is going to get weaker. the sub will work but may not play as intended by the manufacture. ive done a sweep on a properly broken in sub and a sub given hell. no difference. test was done on a cheap ass woofer though.

as for knowledge... google, youtube: building subwoofer, recone subwoofer, how its made speaker, ext.

fixmyspeaker.com

after reconing i typically do a break in process just to test the glue is holding properly. to me breaking in is just the time that it takes to loosen the suspension. i typically give it hell out of the box.

hay team bassick what part of cali do you live? shitty thing is im in honolulu so i would need batteries boated over using aloha freight located in compton.

ok just looked at the site. so i simply use the 12 volt post to run my 12 volt system? this seems very feasible.

how would i run my 12 volt without a step down?

i dunno. i see guys pulling 10volt on 12 volt set ups all day. i know its not good. talking to some battery manufactures they say running the battery down like that is shortening the life of the battery but technically its ok on deep cycles. back on the 16v topic. i have a 01 sequoia so dual alts wont happen. i have a 300amp mechman in there now but i rely on battery bank due to no way in hell am i fitting another alt in there. im going to have to isolate and step down the voltage for the rest of mt 12 volt system. for that is why my concern is voltage drop.

at what point on voltage drop did you feel you should back off?

what did your batts voltage rest at?

can we please oh please stop pushing the 12 volt issue, maybe talk to me about what makes the 16 volt unstable?!? on another topic i ask about lithium and i get bashed on why not just run a 16 volt system. now this....

ok. i still would like to be enlightened about the 16 volt systems. everything we do is not cost effective. having 2 16ks is far from cost effective. making the most of a system is the game right?

well that still leaves me curious. anyone running 16 volts to chime in?

anyone?

i never ran one before. what kind of amps are you running and what kind of voltage drop do you guys see? how low voltage can you go before you loose major amperage output from the battery? reason im asking is because im going to start a build on my 2 sd 16ks and im debating on going 16 volts. i remember seeing in a thread that murillo said its best to run a 12 volt system for daily system on these amps. i want to get the best results but want to know what im getting my self into.

im just asking at what point of price would a lithium be more appealing?

what would be a fair price for it?

good points. i dont know if your aware of it but lithium has higher ratings compared to what we use now across the board if we go by casing size. its just the price is right up with it across the board. im not willing to step up to 16 volt and no way can a dual alt fit in my 01 sequoia. if you or anyone can get me a bracket with out losing anything id pay top dollar for it. edit: even with a dual set up i still would need a huge bank.

what #s is it doing in the mid 30s?

i see your point and agree. only way i see this working is if someone doesnt have space. if you could only fit 3 group 31s you could double that power in the same amount of space. im kind of in that situation. no way in hell is my alt going to keep up with my amps. i rely on battery bank.

this is for car audio. it can charge off an alternator. i was just saying it can be used to replace a starter battery, for some reason i thought people would understand by replacing it as a car starter battery it makes scene to charge off the alternator. im using a group 31 as an example because the performance characteristics would be similar.

im not saying to use it as a starter. just that it can. im just getting a feel for this. lets try to keep xs out of this i got it. you feel xs is god when it comes to batteries...

im not talking about xs. if there was a lithium battery that can charge off an alt. no problem. you can use it as a starter replacement. is it worth it?
