is this a good deal

[WhoDatPanic]

I saw this on my local craigslist and i talked to the guy he said the l7 is a 12" with the custom box with a no name 1000 watt amp for 200 ? is that a good deal?

eh... I don't like the whole kicker scene of things
I think you can get way more for your money but I have learned that bump is bump

it won't be a true 1k watts though I'll tell you that expect to get about 300-400watts out of that amp

 

[WhoDatPanic]

so would you get it i dont want some huge ass system i still need room in the back and i would of course paint the box hopoefully i could color match it like i did my grille... but is there a way to tell if its broken or blown ? its not hooked up he said

 

[thehoe92]

if you don't want to go big I'd say its a decent price if you get the sub, amp, and box and none are blown

take a DMM with you if you decide to go look at it, set it to OHM's and test the coil(s) on the sub
they should be right around what is slapped on the magnet

if its close to 0 or like 923413612 ohm then its blown

also push on the cone and if you hear any scratching or its really stiff and goes in but doesn't come up then its blown

 

[WhoDatPanic]

lol first what is a dmm ? and how would i do that if its in the box ? yea i used to have a l7 in my car and it hit freaking hard thats about is loud is i would ever want.. would this take up a lot of room in my back ?

 

[thehoe92]

a digital multimeter

well if you are serious about it unscrew it and take it out of the box, if nothing is wrong with it then the seller has nothing to hide

if that box doesn't sound good then you can always get a design for another one and build it yourself, that way you control the dimensions and how much room it takes up

 

[WhoDatPanic]

how much are those testers ddm things is that the only way to pretty much tell if its blown or not i mean if i pushed the cone could i tell

 

[thehoe92]

thats the for sure way to tell they are like $20 from kragen
its a good tool to have, measures voltage so you can check car batteries to see if they are dead that type of thing

but yeah if you push on the cone I'm sure you will be able to tell

there are some noises that you aren't supposed to hear and they are pretty obvious lol

 

[WhoDatPanic]

i have a voltage thing that looks like that is that the same thing ? how do i test the sub ?? what would i hear if it was blown

An L7 needs a lot of power. Especially if it is in a sealed enclosure. I would look to buy a refurbed L5 12" off of ebay and get a decent AMP. I have been running my refurb L7 w/dual voice coils wired in parallel at a 2 ohm load in my boat powered by a Kenwood 1800 watt class D mono AMP for 2+ years. An L5 will be much more efficent with lower powered amps. You can get a refurb L5 for around $130 shipped on eBay.

Also if the box the L7 is in a prefabbed ported enclosure, chance are it isn't ported correcty for the sub. Ported boxs need to be designed and constructed for the sub and the type of music you plan to listen to, along with the frequency you plan to cross over at. Sealed enclosures are MUCH more forgiving.

Sorry for making this complicated.........

Oh yes, one more thing. If the sub is in a truly sealed enclosure, you won't be able to move the cone much if any at all by pushing on it. So don't use that as your only method of test if it is blown......

 

[WhoDatPanic]

its in that picture it looks like its a ported box

 

[drowndindreams]

dude, that sub alone is about $200. The "custom box" I'd say another $100. Then a 1000 watt amp, even higher. JUMP ON THAT!!!

 

[WhoDatPanic]

haha yea i want to im just scared because i dont know if it will work or not ... how do i test it with that meter....?

 

[jomulk56]

Ask him to hook it up really quick. If he wants your money and has nothing to hide he should do that.

 

[TnTahoe]

you can go to walmart and get a dmm to test the sub and just return it when you are done if you dont want to keep it, and to test the impedence just turn on the dmm and set it to ohms which is the horseshoe looking symbol and hook the speaker leads to it, we cant really tell you what number to look for unless you find out if the sub has dual 2 ohm or dual 4 ohm voice coils, so ask the seller which voice coils the sub has and how are they wired series or parallel

 

[WhoDatPanic]

yea i did but he said he sold the car it was hooked up too... and okay so if i did that i would just put the ddm tips to the end of the sub ? lol im a noob at this im so confused

 

[TnTahoe]

ask him if the subs are dual 2 ohm or dual 4 ohm

 

[WhoDatPanic]

okay i will... where do i plug the red and black things into on the ddm i have one but dont know where they go ? and where would i put it on the sub...

---------- Post added at 11:11 AM ---------- Previous post was at 11:07 AM ----------

he thinks its 4 ohm..

 

[TnTahoe]

put the blk lead in the com port and put the red lead in the side with the horseshoe symbol, look at the pic on the first page and the red plug would go on the right, and just touch the red lead to the positive terminal on the sub and black to negative terminal

ok well if they are 4 ohm and there is only one set of wires coming out the box then you should look for about about 2 ohms if the sub is wired in parallel
and if there are 2 sets of wires coming out of the box then each set should measure around 4 ohm

 

[WhoDatPanic]

ok do you think 200 for this is a good deal i cant tell if the box looks good or not he said he built it to exact specs for the sub... and the amp isnt the best but he said it works and it makes the sub hit good i dont want a ton of bass i dont care if it is world class but i want some...

so if i test it and the meter says other than 2 or 4 then its no good ?
