Pretty much sold me on infinity kappas (After i have me a test listen on a pair). Lots of neat features packed into these, and the 2 ohms will take advantage of my amps capabilities.

Answered me alot of questions about the various features on my jl e4300, so thats cool. I still dont understand if its speaker or wiring that makes it 2 or 4 ohms.



So, big props to crtuchfields online vids, if you need to find some info out i highly recommend.

My first vehicle was a 2-door '87 S10 Blazer, 4x6 infinity kappa plates in the dash and infinity kappa 6x9's in the rear, 2 pioneer 12's in the back, I really miss that system, and that blazer... sold it because it was 2-door and had the 2.8 and the kid totalled it 2 weeks later.

dude that sucks. Hey your 89 blazer is two door too Just needed a 350 on that s10 lol. Vrooooom!



I think its the speakers that make it 2 or 4 ohm, not the way its wired(unless its subs i think)

Ohm is the measure of resistance across the speaker in this case... It is the speaker that determines how many ohms of resistance.

It is both.


In series wiring you can take two 4 ohm speakers and create an 8 ohm load. In parallel it would create a 2 ohm load.

A speaker has its own resistance, usually 4 ohms in car applications, but then when combined with other speakers you can change the overall resistance.

They make dual voice coil subwoofers just for this. You can put each coil on a circuit alone, and have two 4 ohm loads, or you can wire them in parallel as one circuit and run the circuit at 2 ohms, usually on a dedicated subwoofer amp that is made to run high output at 2 ohms.

Thats just what i was looking for thanks brother!

realized the first audio "install" i ever did was so loud. Do not laugh cause it worked.... I was such a noob.


My 77 had a dealer installed radio, some made in taiwan pos. Had one wire going to dash speaker, other speaker wire ran to ground (previous owner did it dont ask). So, without anyones help i decided i was going to wire (suprised no fire happened). I hooked one wire up to the speaker lead, and one up to the other speaker lead, (which i later found out was actually a ground wire) and ran them to 4 speakers, 2 alpine 6x9s, and 2 pioneer 4's i bought. It must have been at less than 1 ohm, im surprised radio even worked .

Best of all, i ran it through a single crossover i found in a box of random junk my brother gave me, the 6x9s on the mids/lows, and the 4's on the high. didnt sound bad at all to be honest

Later on i rewired it correctly with a kenwood digital face dual post, rears to some 8' mtxs, and fronts to the 6x9s (actually had the 4's wired in as well at one point, but had them in series with the 6x9s), all behind the seat of course




Wow, things we do when we are young and dumb.
