I have a box with 2 - 12" Rockford Fosgate Punch HE subs and want to know how much power to give them. They are 200w RMS max, should I go with an amp that puts out 200w RMS x 2 or can I go with a lower RMS amp? Should I go with a single channel amp with a higher RMS for both speakers?

 

The people at the audio shops always want to sell whatever is the most expensive and you can never get honest help from them. Any help from yall would be greatly appreciated!

I would go with a single amp a nice JL500/1 would be sweet with those subs

Is JL Audio pretty good? Im only familiar with the Rockford amps. I was going to go with a Rockford mainly because of the remote bass control, but since JL has that as well (i think) Ill look into them if there any good.

 

Isnt there a way to wire up 2 - 4ohm speakers so they are only 2ohm?

Ya thats called parallel wiring. and JL has a remote bass controler too (I use mine all the time). Its a JL RBC-1. Rockford has some decent stuff but I personally love the JL amps and subs. You wont be disapointed!!

 

here is how to wire those subs parallel off a mono amp

if they are single voice coil subs, yeah you can wire it to two ohms.

But if they are Dual Voice Coil Subs, you can only wire two subs to be either 4 ohms or 1 ohm.

 

edit- haha GF7PE beat me to it

Quick question on ohms. Is there any way to hook up 2 rf power hx2's to a 6 ohm stereo, sounds rare but just wondering? Dual voice coils as well.

nope no way with those subs, in any configuration. If you want that configuration because you have an old amp you want to keep, you might as well just bite the bullet and get a newer amp. You wont find very many, if any, subs that are DVC that will make a 6ohm load. You are going to get a 4 ohm or 1 ohm load out of two DVC 4 ohm subs, and a .5, 2 or 8 ohm load out of 2 ohm DVCs. There arent very many amps that can take a .5 load, so you should really just write that off the list of configurations.

JL makes some really good stuff, it's just a little pricey. the newer JL amps give you the same amount of power from 1-4 ohm. and isn't some of the older JL subs, not sure about the new ones, that were dual 3 ohm voice coils?

      With large equipment or deep mud it is more of a use the higher gear to avoid spinning tires, getting stuck because of spinning tires and doing damage to your machine. The idea is if you run out of torque before you spin tires you can still downshift for more torque. If you are just spinning your tires in the lowest available gear you are stuck and things break.   Automatic transmissions, traction control and electronic transfer cases change the calculation a little as you the driver have less control over each piece.

      My First Project and GMC has me stumped

      are there any codes? with lots of rust, perhaps disconnect/clean both sides of the connection/examine cable ends (the wires) for corrosion going into the sheath & replace if necessary/reconnect ALL the power AND ground cables between the battery, engine, frame, cab, fuse box and starter charm.li (website) has a no-start diagnostic procedure you can work through to get it working.

      OCI, not when but why?

      By Chuck FB · Posted

      Its no wonder you've gravitated to the oil types and brands you have in later years after trying certain brands and one being a specialty oil or at least very hard to come by up here and the other would have been a commonly found oil of the era and the vastly different outcomes as a result to using the vehicles in question the same distance for an OCI . It shows what marketing hype can do without actually having the product to back up the claims and that is no different now with the insane claims that are written on the side of a bottle of oil from some of the off the shelf oils.    What has surprised me and I was already finding this out before I bought my truck with the GDI engine, that this newer fancy technology that seemingly would suggest better fuel economy/emissions with this high pressure spray of fuel is not in reality kind at all to the engine or at least the oils life. Yet they insist on claiming long OCI with this technology just like they did with the port or similar type fuel injection systems when in reality its a step back in oil life to have a GDI system.    I think the mistake your making Grumpy is that your not sending your samples to Blackstone and getting the feel good glowing report that you can run it another 1000 or more miles and then send another sample where they say run it yet another 1000 miles and on and on it goes until your sending in something that looks a lot like road tar and then they may suggest you change your oil within the next 1000 miles 😆

      I am guessing that engines of that design back then had a better ability to be abused and survive longer than a new design engine with the long timing chain and the overhead cams and phasers etc. But I would never guess that an engine could go that far and not fail spectacularly or at least die a slow death.
