mocrawlin Posted May 25, 2013 Author Report Share Posted May 25, 2013 yes the surround came apart and sounded like a real bad fart box. lol i measured the coils ohm rating and it came to 3.8 ohms. so i bought the 100rms 4 ohm kicker comp 8.

mocrawlin Posted May 26, 2013 Author Report Share Posted May 26, 2013 would a transfer line box be outta the question for this sub hooked to the factory amp and h/u? Link to comment Share on other sites More sharing options...
Joe X Posted May 26, 2013 Report Share Posted May 26, 2013 would a transfer line box be outta the question for this sub hooked to the factory amp and h/u? You mean a transmission line box I guess, not if you have the space for it, those can be large boxes even for small subs, are complex to build and are made up of many parts. Many factory amps work on a custom impedance, probably that may be part of the reason you don't get decent output, to me, any stock audio gear belongs in the trash can most of the times.

mocrawlin Posted May 26, 2013 Author Report Share Posted May 26, 2013 yes transmission line box. i have figured one up and it is just under 31 inches long, 8.5 inches wide, and 16 1/8th tall. tuning comes out at about 37.5 hz. not sure if i should do it that high, but alot of guys say build it to match the sub. so that is what i designed it after. 30 sq port and close to 40 hz. i figure a little lower wont hurt, and it wont be as high. what do you guys think? i see alot of guys saying it takes no power to run a trans line, but, they all say you must have the amp set right. but i dont have any adjustment for my factory amp.

Joe X Posted May 27, 2013 Report Share Posted May 27, 2013 The C84 has an SD of 32 square inches and a Fs of 36.8Hz so it looks good if your layout was done properly. Link to comment Share on other sites More sharing options...
mocrawlin Posted May 27, 2013 Author Report Share Posted May 27, 2013 i may give it a try. its just wood and screws, right? LOL hope i can upgrade the h/u and get a sub amp soon so i can tune on it a lil better. Link to comment Share on other sites More sharing options...

Joe X Posted May 27, 2013 Report Share Posted May 27, 2013 A T-line is just a port, displacements don't have an effect on it's operation. Link to comment Share on other sites More sharing options...
mocrawlin Posted May 27, 2013 Author Report Share Posted May 27, 2013 oh, ok. good to know. the calculator i am using to get an idea of what i want to do asks for all of that. LOL still learning this stuff. i had never heard of this type of box until a few weeks ago when i was looking at buying 2 diamond 10 inch subs, and they were in this type of enclosure. and i may go get it now that i know what it is, but it is big!

mocrawlin Posted June 3, 2013 Author Report Share Posted June 3, 2013 well, it is late, so i could not jam on it much yet. but with the minute i had the new box going all i can say is wow. did the transmission line box, and it makes the lil 8 sound much bigger. hits lower and sounds deeper also! next up, a couple of high power 10's! each in its own transmission line box. anyone have any suggestions on 10's that will work good in these style boxes that will eat up 750 to 1000 watts for the pair?
