I'm new here, but I've been doing car audio stuff for years so I know the basics. However there is one thing that I can not get the correct answer to, and that is how to measure an amplifier's RMS!
I read through may pages of forums, but every single one of them just got me more confused. Since I don't have a fancy equipment to do it all I've been wondering if you guys can help me out. What kind of equipment and methods do I need to determine it properly?
Also I've been told that the good old Ohm's, and Watt's law are not working correctly in this scenerio, witch I doubt but who knows, I might be wrong.
And filally here is the video, that got me mixed up to the poin where I can't understand anything:
I'm kinda stuck on this one, and it makes me go crazy. PLS HELP!
THX in advance!
Alright, i am sure you guys have heard this many times before.
I have 4 18" FI BTL N2 subwoofers (V1) and I want to install them in my living room.
Being dual 2 subs... I could wire one to one amp at 4ohm in series.
So, guess ill need 4 amps. Any suggestions? i have been looking and found a few dayton audio amps..
I havent found anything that does around 1500 watts rms at 4 ohm. I am assuming this isnt common in home audio?
Or will i need to hook up my welder to my 750.1? Lol.
I am actually leasing this car so ive been trying to do the install so that at the end of the lease I can return it all back to stock. I'm running 2 12 JL w3 on a JL jx 1000/1. Just got a new box for them to match the specs JL prefers. Atrend makes a box called 12JL01DV. Not exact but pretty damn close to spec. My old box was too small for these subs. For the mids and highs in my front stage I have Focal Auditor 6.5 components. Made custom speaker rings out of some scrap mahogany I had. I wanted to install the in the factory location so I cut two identical rings of .75in thick using a router and glued them together. Used this rubbery foam weather stripping as a gasket around the speaker to make sure it was all sealed at the door panel. For the tweeters the actually fit almost perfect behind the door panel in the factory location. I used steel back strapping, hot glue and sound deadner around the edges of the opening to seal it and prevent rattles. Also made speaker rings for the pioneer d series coaxials in the back doors for the rear stage. Bought some KnuKonceptz 1/0 and ran it all the to back and split it off with 4 gauge using a distro block for the power wire and ran 16 gauge to the mids and highs. Had some spare 1/0 and did a big three upgrade and swapped the battery for an Interstate MT7. Way too many times my car died on me with the little stock battery and its a brand new car!
