Final touches (tuning and whatnot.)

the loudness feature can cause your signal to clip at higher volumes. its intended to be used at very low volumes to boost bass and treble.

i keep mine off,but like i said its for low vol situations. be careful with it.

as far as the sub vol all the way up, it would depend on the music. sometimes it has to be all the way up for me.(80's music with no bass) and other times it needs to be way down.

the gain for the sub amp...well.... do this turn the head up to 3/4 or so and while playing a bass heavy song turn up the gain. when the bass starts to clip back off the gain a lil. then it should be set. can be done with the mids and highs too.

 

2x100WRMS 4ohms
2x150W RMS/2 Ohm
1x300W RMS/4 Ohm

 

What is the exact model of your JL amp? and what is your sub again? is it a dual 4 ohm sub or a dual 2ohm?

Ok, if your sub is a dual voice coil 4ohm sub then you won't be able to bridge your poineer amp. When you bridge most amps they can only be bridged into a 4 ohm load. Your sub, assuming its a dual voice coil 4 ohm sub cannot be wired into a 4ohm load. It can only be wired to either a 2ohm or a 8ohm load.

 

I also got confused before with the ohms stuff.

you can toy around with this to help you understand it better...

just play with the number of speakers and the number of voice coils. this thing really helped me a lot

 

this has been comming up alot latley, what are you guys talking about when you say 'bridging' the two amps. I am really not sure how you intend to do it, unless your talking about using preamp outs equipped on the amps, or passthroughs, or using a DA and daisy chaining two amps off one RCA. or do you simply mean using two different amps on diff subs? to the best of my knowledge bridging has to do with speakers, using the opposite polarities from opposite speakers to optimizing the output of the amp correct? or am i lost now too? is there a new kind of bridging?

 

the term i beleive is strapping 2 amps. 2 identical strapable amps.

 

no worries, dont fret, i was just wondering if it was an area thing maybey, a couple post in the last couple weeks have used the same term and i was wondering if i had mixed them up, my brain is prone to just shutting off on a daily basis, i get like a good 6 hour burst then iam out for the rest of the day on a half tank, so if i work before i come back to the boards its over. :lol:

 

Hey, i don't think you can bridge two amps together or strap them together unless the amps are identical and are strappable. It will say in the specs if they are or not. I had one of those pioneer GM series amps, they are weak ebay crap and don't take any kind of abuse so don't get attached to it lol. You can bridge most amps separately but the amp has to be bridgeable in the specs and is usually done by using the negative from one speaker output and the positive from the other set of speaker outputs, this tells the amp to put full power now to the wires you are using to the sub. So say the amp sees now a 4 ohm load and say it puts out 100 watts at 4 ohms, if you wire your sub differently and get a 2 ohm load, the amp sees this as there is half of the resistance so it can now push twice the power and it will be pushing 200 watts. Hope this helps sorry i have trouble explaining sometimes lol.
