Ok I want to get a JBL 600.1 to run 2 JL 12W3's and i want to wire it into 1 ohm. I was wondering if the amp could take this. They say it is 1 ohm stable and i was wanting to ask someone if they ever ran one in a 1 ohm load. Cause i don't want to get the amp and hook it up and crank it and it only plays for 5 min and turns off. I want to make sure that i don't have to worry about it and get all pissed off if it doesn't work. If there is a doubt if it can run that load then i guess i should get the JBL 1200.1 and run it in 4 ohm mode. Thanks.

 

everyone that i've heard running em had no probs with them. as long as your amp isnt glowing red hot, you'll be fine. and since its a class d, heat wont be an issue and these amps are built pretty tough. i wouldnt be worried

 

The 600.1 should be fine with those JLs and at 1 ohm mono. Should sound real loud and clean if you set it up properly. Enjoy it.

 

if i were you I'd just spend teh $$ and get tthe 1200.1 that is what I plan ot do

 

Yeah I was thinking about it getting the 1200.1.... but I'm on a budget and I'm only 15 so money doesn't come along too quick. Do you think the 600.1 would be enough... I'm lookin for clean bass that is loud at times.

 

if you are going to run an amp of any kind at a low impedance (1 ohm), then you should the voltage and the carrier to get it there, IE 1/0 guage wire, and possible a capacitor or extra battery in your system. As long as these requirments are met, you should have no problem what so ever. Hope thats of help to ya

 

depending on what other amps you have 2ga is perfectly fine for 600rms, and an additional battery causes more voltage problems, not solve them.

 

I was planning on running 4 guage power wire with a cap. Will this be good enough... I think it should be adequate.

 

4ga is just too small really...

I would really look into 2ga...speaking of....in about a month or less I will be ripping out my 2ga (going with 0ga), its prob 18' or so in length and should be enough for your camaro...

If you want nice new stuff, head over to www.partsexpress.com and look into their power wire, you can get 2ga from them for pretty cheap and its just as good as any cable Stinger(and similiar high-$$ Co's) ever made.

 

uhh.. a 20 foot run of 4 gauge wire is perfectly fine for at least 100 amps.. the 600.1 uses 2 30 amp fuses, so we have 60 amps there.. you want your wire to be able to handle 10-20 more amprs than the fuse rating.. so you'll need to be able to do 70-80 amps.. it does depend on what other amps you're going to have in your system, but 4 gauge is more than adequate for a 600.1 alone...

 

but what if a yr or two later he wants to go to the 1200.1, or he has another amp that draws 40amps or so? Well, then you have to buy all new wire and run it again. 2ga is not much more expensive than 4ga and will handle any sane system with ease. Get 2ga and you won't regret. I've been there, done that and have had to run new wiring in my car many times.

 

Agreed, If you are going to go through the trouble of ripping your interior out you might as well do it only 1 time. Use 2 Gauge Power and Grounding Cable. As far as the JBL 600.1 vs 1200.1 and 1ohm vs 2ohm.. Metz Man we talked about this awhile back and here was my reply.

I'm also curious where you are getting a 1 ohm load? Have I been gone that long? 12w3's have 2-3ohm voice coils so each sub would present either a 1 1/2ohm or 6ohm load. Then when matted to another identical Subwoofer the ohm choices would present a choice of .75,3,12ohms. My recommendation would be to wire each sub Parallel and then wire both subs Series with each other which will present the Amp with a 3ohm load.

My subs are 4 ohm DVC's so I'm going to wire the coils in parallel and then I going to wire the subs in parallel. This makes a 1 ohm load.

 

just out of curiosity, how does the 1200.1 do on distortion? unless im missing something, it costs around 300 dollars for 1200+ watts at 2 ohms.. so 25 cents a watt? that kind of disturbs me.. what are the downsides to this amp?

 

I guess I've been gone longer than I thought.

 

Distortion is higher than most Class A/B amps, but its still well BELOW the audible range. The only downsides to the amp is its odd styling. Some like it, others don't. I'm one that doesn't care for it. But hey, if your on a budget and need 1200-1300rms (it puts out a tad more than rated) then its the perfect amp.

 

hmm i see.. thank you much!

 

NP. I can't recall ever hearing anything bad about those amps, lots of good!

head over to www.carsound.com Richard Clark on Audio and then search for JBL 1200.1. That should give you a lot of threads to search for info on.

 

I got the amp and it looks great... I didn't get a chance to hook it up yet. But I have a question... it is a mono amp and it has 2 speaker outputs... So i can hook up my JL's like it is a 2 channel but they will play in mono and present the amp with a 1 ohm load? I think that is how it works. Thanks for all the help guys. I just got done with finals in school and I'm about burned out so I am trying not to think too much.

 

yup, hooking up one sub to each "channel" of the amp is the same as wiring them up in parallel.. so 2-ohm subs hooked up to each "channel" would present a 1-ohm load..
