http://www.sonicelectronix.com/item_37765_U.S.-Amps-XA-800.4.html I just bought this amp originally planning to run four JL-TR525CXi after putting the first two in and testing the amp out i realized that the speakers sound ten times better than my jeep stockers but are still lacking a in the bass area..(duh 5.25).....so i am now if possible gonna Bridge channel 3 and 4 for a single 8 inch JL Sub......my question is, what ohm rating must the sub be for my best results?....i dont really under stand the whole ohm thing.... Any help is greatly appreciated.
4 Ohm? I'm thinking this is correct because it say bridge x2 for 160w@4ohm........nvm I think I got it!
It does look like you can only put a 4ohm load to that amp if you bridge 2 of the channels. So "IF" that is correct, and if you're only going to run 1 sub, what I would do is get a 2ohm dvc sub and wire it in series. That will give you a 4ohm load to the amp.
thanks! bookmarked! any specific benefit with going with a 2 ohm in series? why not just a 4 ohm sub?
Basically because you should get a dvc sub in-case you want to upgrade to 2 subs down the road. Look at all of the wiring diagrams and try to make sense of them. There are more ways to wire a dvc sub so it gives you a lot more options. You can't wire a 4ohm dvc sub to a 4ohm load. If you wire it in series you'll get an 8ohm load and if you wire it parallel you'll get a 2ohm load.
ok....so of im not really into audio porn the getting a single coil would be ok? im really looking for the simplest route.....this is goin in my postal jeep/daily driver and the box will have to come in and out from time to time ( i work weekends only)
A bumpin postal jeep! Awesome!!! Ok, then yes, you can use a 4ohm svc sub to get a 4ohm load. Still think you'll be happier down the road with a dvc though.
im sure i might catch some criticism here.....but im have a hard time matching subs up to sealed boxes when it comes to sq footage...... this is the sub i intend to use.....it requires .5 sq ft www.sonicelectronix.com/item_27301_RE-Audio-REX10D4.html this is the box i can find closest to that req and its .58 www.sonicelectronix.com/item_1_10ANTCM-Subwoofer-Enclosure.html is thos gonna be an issue?
