were reasonable amps in their time, (if its the one i think it is)

[diablosvy]

Yea they are quality amps from what iv heard.
As for matching the power I didnt quite understand [ERRR] you said...whats the RMS of both the sub and amp, and what voicecoil config. does the sub have?

[fiestamodder123]

hi,
my sub is a single voice coil (1 p+/-) on the back sub says on the cone that its 1000watts but i know thats a peak figure (jbl)

i also have 10" infinity that is rated at 1250 watts max and 25o rms

i also have a 10" kenwood that is rated at 200 watts rms

i s**t 12" type vrX sub thats rated at 250watts rms

1 blaupunkt 10" thats rated at 250 watts rms (i tried to kill this by running about a 1000watts rms through it with my mate vibe mono amp and it took it for 3 weeks and still doesn't smell funny

which sub do you rekon i should use with this amp to get the most posible bass

thanks

Good question, TBh I havnt heard any of them (i dont know the model numbers) even then I wouldnt, TBH Inifinity 'generally' speaking are more SQ than SPL, Kenwood havnt a clue JBL are from what iv heard pretty bassy in a ported enclosure...you are going ported right? Sealed wont get enough bass especially since your underpowering the subs, since ported is more sensitive to power IIRC.
As for impedence I meant 4ohms or 2ohms

all the subs i have are in sealed enclosures and im not sure about box volumes and things to get another ported box made up, i do have a 12" ported box but its an old box from around the time when everyone was running 15" "TORNADO subs with paper cones and reading revs thinking it was "SORTED" and it really is pooy ,might even be home made oh and it rattles , all i want is hooooooge amounts of Bass on a budget , oh and i have an alpine headunit ,cant remember the model but its got a 4v sub out and a motorised face was about £500 3years ago

thanks

[diablosvy]

If you want huge bass, ported is the only way to go im afraid...get yourself a copy of winisd and have a little play around, and design your own box if not i'll giv you an idea of the sort of dimensions you would need

Mike

[fiestamodder123]

is it possible to port one of my existing boxes , if so what would be the deciding factor on the sizes and depth of the ports? I will need to take some measurements off of the box i already have and work out the volume of the box,the box i have is just a basic 12" sub box from my local motor factors think its made by XL or something like that was about £30 (same one that hellfrauds try and sell you if you buy a 12" sony pentagon sub.

Thanks

It would be more trouble than its worth IMO to convert the box, if you want I can design a ported box, if you give me the model make and number then i'll have a look, if not dont worry

Mike

[fiestamodder123]

that would be apopreciated mate , then i would just need to find someone with the skills to build it for me ask me to fit an engine or spray a car and yeah its no boyher but ask me to cut a straight line in a piece of wood pffft no chance , ill need to find out the model of my sub first as all i no is its a twelve inch jbl with 1000watts writen on the front of it , how much would you be wanting to design the box for me

[diablosvy]

Free mate, i wouldnt charge, yea I really need the model number or the Thiel Smalls (T/S parameters) , BTW what music do you normally listen to?
Yea I know what you mean...thats why a jigsaw and a ruler/pen is the only way for me, as i dont have an circular saw

[fiestamodder123]

mostly dance trance and techno mate , but a lot of metal as well,still dont know what model my sub is
