    Ah it's for my girlfriends car, she doesn't even know bass remotes exist haha

    about to switch my order to http://www.sonicelectronix.com/item_35819_RE-Audio-XTX5000.1.html

    I cant make my fucking mind up

    I don't know anything about RE's amps man, I've never heard anyone reccomend them or talk about them

    hmmmm ok

    Ill just go with the brz see if I like it, if not Ill just get a sundown

    you guys are looking at the fuse ratings wrong. something i read on fusing.

    just for future references, a good spec to look at is the fuse rating.

    40a x 5

    40 amps * 5 = 200 amps

    200 * 14.4 = 2880

    2880 * .8 (typical class D efficiency) = 2304

    hmm your close.. try this..

    I measure 12.8V, take 65% eff and my amp have two 30 amp fuse:

    30A * 2 = 60A

    60A + 1/3 = 80A (current point to blast fuse)(sinwave input-----squarewave output)

    Now we need to calculate the RMS output value ...we will use 60A value

    60A * 12.8V = 768VA

    768VA * 0.65 = 499 ...say 500Watt RMS output

    it is a simple maths formula which is average power = work done (unit of work is the the Joule) divided by time taken (unit of time is the second)

    the unit of power = Joule/second (J/s)

    Si unit of power is watt (w) = 1 J/s

    so what we are looking for her is work done = force x distance to give us the Joule.

    then we can work out how many watts it putts out which is power = work done/ second will give you how many watts anything is putting out

    Hmm. English? Lol my brain just pooped out.

  11. Subaru WRX STi

    in Engine and Performance - Anything for that couple extra horses!

    On a 2004 WRX STi, I've seen its power and speed, but its strange that with some upgrades to a Mitsubishi, it can go past 160, the thing is, how can you really make a Subaru like that get higher speeds (not higher starting speed) without breaking the engine, and other options that are not nitrux. Thank you in advance !

    Swap out the tiny 4cyl for something bigger and you will go faster http://www.jegs.com/i/World-Products/955/108061/10002/-1?parentProductId=758062
