View Full Version : 2 10'' Kicker L7's
08-23-2003, 05:59 AM
i want to get 2 10'' L7's and i was wondering what amp i should get. They are 4 ohm subs and i don't really know much about amps and ohms. Also what would be a good box to put them in, a sealed or ported box. And how big a box should i get. Also are they good subs. So can anyone help me out?

square subs sound like crap...no matter who makes them...its just the way it is...thats why 99.99% of subs are round...they sound better
but square subs will hit harder...more surface area...
so if you want loud...these are the subs...if you want any type of sound quality....go with something else
but they have a low sensitivity rating...meaning that it takes more to push them
im not sure how they compare to round speakers....but lets say you have 2 subs...both get 100 watts rms(continuous)
one has a sensitivity rating of 85.6(the L7 has this rating) and the other has a rating of 88...which is about average...the one with the 88 rating is going to be louder
but if youre stuck on these speakers...theyre rated at 600watts rms each at 4 ohms
and you want to
so find an amp that has 1200watts rmsx1(channel)at 2 ohms(two 4ohm speakers has a load of 2ohms)
im going to recommend the rockford fosgate bd1500.1...it puts out 1500x1@2ohms...which the kickers can handle

I would need two amps then if it is a one channel amp

Then just mount them in parallel on the same channel. That would be how two four ohm loads become a single two ohm load. Read some of the other posts to better educate yourself, it will make things a lot easier on yourself.

he's correct, even though its a one channel, you can still put two pairs of speaker wire into the positive, and two pairs to the negative
to wire your speakers in parallel
connect the positive leads of both speakers to the amps pos. terminal, and negative to negative in the same fashion
that gives you a 2 ohm load

dude L7's only come in DUAL 2 or DUAL 4 ohm coil versions...
so firstr - do u have the dual 2 or the dual 4 versions... ???
secondly -- you'll need @ least 750 per sub - preferably a little more ...
1500 - 2000 x 1 would be good -- just be sure itsat the right impedance -- so figure out if its D4 or D2.

the 4 ohm model
so a 1500 1 channel would do fine?

if the subs are 4 ohm...then yes sir the 1500 would be perfect

if they're the dual 4 ohm you'll either need 2 amps or you'll have to run the pair of subs at either 4 or 1 ohm... If you can still switch to the dual 2 ohm you can use a 2 or and 8 ohm load... for the 2 ohm load you'd need to bridge the speakers in the box in series and at the amp in parallel or visaversa it makes no diff where you do what but you want one of each bridge type... and example of how to do this is as follows.
When mounting the subs in the enclosure you'll have one set of terminal's on each side of the magnet, one for each Voice Coil (vc) You'll also have a "box terminal" inside the box it hooks up to the sub and outside the box it hooks up to the amp. attach the positive that hooks up to the box terminal to the positive of the first vc. hook the negative of the box terminal to the negative of the second vc. hook the negative of the first vc to the positive of the second vc. this will give you a 1 ohm load if they are dual 2 ohm speakers and a 2 ohm load if they are dual 4 ohm. you would then finish mountin the speakers in the box. to hook up to the amp you would run from the positive of the amp to the positive of the box terminal leading to each speaker and from the negative of the amp to the negative of each box terminal. overall this will give you a 2 ohm load with dual 2 ohm VC speakers and a 4 ohm load with dual four ohm vc speakers...
Hope that helped :D:D
bty i've heard that the l7's and l5's do best with vented enclosures. and typically you'll need to find one that is designed for that sub. they take up a lot of space and will cost a few bills but you'll get the best sound. most kicker dealers will have something along those lines available...
Happy installing and enjoy the system :D:D
bty if you realy want to hit em hard and can afford a grand for an amp look into the usamps 2000x which will put out 2000wx1 rms at 4 ohm, if you have the dual 4 ohm vc subs it would sound sweet :D:D

the l7s dont come in a single 4 ohm voice coil?
08-27-2003, 11:59 PM
i'd doubt they would...
