new sub need help
gday guys i got given a cerwin-vega 12 inch woofer, at least i thik its 12 haha it puts out 96db and im not sure what kinda amp i need, i honestly dont wanna spend to much and another mate has a cheap amp for sale do they all work?
i have a pretty handy mate who will help with the install, i hope haha
Custom Car Stereo Systems
It should "work" with almost any amp. If you can get the details of the amp your mate has then we can tell you how well it'll work and basically how to wire it up. You do know you'll need a box too?

yeah i figured ill just make one out of mdf, i have been told i need to insulate it as well........are there certain sizes for the box
Custom Car Stereo Systems
Whether to insulate it or not is up to you. Yes there are general sizes to stick by. Being a Cerwin Vega i assume it'll prefer a ported box. But these are harder to make and get right. If you give me the model number i can figure out a good box design and get back to you with dimensions etc.

good as! are they good quality subs? it says on the back xl-12d i have the serial number if that helps....052680
Custom Car Stereo Systems
OK well i cant find too many specs on that sub, but going off the "d" at the end i would imagine its dual voice coil, does it have 4 terminals on the back of the woofer (2 +s and 2 -s)?
I reckon something along the lines of 2 cu.ft. ported will be the go. I'll get onto a box program and get back to with dimensions and what size/type of port to use.

yeah it has 4 , are they good qulity woofers? thanks so much mate
Custom Car Stereo Systems
OK here you go....
Its a quick design for a ported box. 350mm High x 600mm Wide x 400mm Deep (~2.2 cu.ft. after displacement). The 4" port should be 250mm deep.
For the port, just go into your local hardware shop and get a peice of 4" drain pipe etc, just cut it down to 250mm, just the hole out of the box and slide it in. Seal it up with silicone etc and youre good to go
As far as the woofers go.....their old school but not bad at all......is the surround still ok?
You'll have to let us know about the amp you wanna get too, as its dual voice coil it makes wiring it and compatible amps a little harder (for you, not me haha).

thanks mate will do that box, mdf sweet?
i just want a cheap amp that will do the job, nothing pricy just on the cheap, any sugestions?
Custom Car Stereo Systems
Yep just use 16mm MDF. Make sure you seal up the joins properly too....you dont want any air leaks
Have a look at brand name second hand amps on ebay....like Kenwood, Alpine, Sony, Clarion etc. Dont be tempted to buy a "powervox" or "kingwood" brand, they are crap. Heres what i found with a quick search....
This isnt a bad amp, if its not too expensive:
2X100 RMS! Jaycar Response Car Amplifier 2 Channel - eBay Amplifiers, Audio, Video, Car Parts, Accessories, Cars, Bikes, Boats. (end time 23-Jul-09 18:41:03 AEST)

so like 55-70 is reasonable, what do i look for to suit my woofer
Custom Car Stereo Systems
If you can get an amp that can produce either 1 x 200wrms+ at 2 ohm or 2 x 100wrms+ at 4 ohm then youre doing well.
Ideally you want a "monoblock" which are designed to run subwoofers. But if you cant get one then a 2 channel amplifier with ATLEAST 80wrms per channel at 4 ohms is the minimum i would suggest.
If you end up getting a monoblock, you'll just need to connect each + together and each - together. Then run speaker cable out of one + and one - to the amp.
If you get a 2 channel amplifier, you'll need to run two lots of speaker cables from each lot of terminals to each channel of the amplifier.
Also be sure you get one with a low pass filter (most decent amps will have one).
Do you have a CD player?
You'll also need a wiring kit. (Power/earth cables, fusesholder/fuse, remote turn on cable and a pair of RCAs mainly).

i have a clarion cd player, it says on the front 35w x 4 dunno wha that meas but yeah, all seems so complicated haha
ill try
haha
Custom Car Stereo Systems
THe 35w x 4 is the cd players' internal amplifier, used for powering speakers. Its actually 4 x 35w max, somewhere around 20wrms per channel.
150db in a commodore =
More like 10-13Wrms... The current 55-60Wmax ones are around 18-25Wrms.
Custom Car Stereo Systems
meh, i said around
150db in a commodore =
well i will probs bid on an amp this week sometime and see what i can get using ur guides hha
1000rwhp
the cerwin vega 12" sub is 350rms i have the 10" version of it.
Do you know exactly which model he has?
1000rwhp
well yes i do the cerwin vega" vega model. The other model is the stoker and he would have said that otherwise.
Custom Car Stereo Systems
Its an XL-12d, very old....circa early-mid 90s.Originally Posted by lachie

As you can see by the post above, it's not the current model sub.
The XL-12D are apparently rated at 125Wrms per coil so 250Wrms total. They also only really suit ported enclosures.
Custom Car Stereo Systems
Sh*t i was close with my enclosure then, lol.
150db in a commodore =
lol, so much that i dont understand, i am gonna get the wood this week and bid on an amp hopefully my head unit works, god im so confused, how much would it be if i bring a proffesional the gear for them to fit it??
Custom Car Stereo Systems
What, you build the box?
If so then i'd imagine around the $120 mark, not including wiring. Somewhere around $170 inc. wiring.
