How you guys think about this amp?

JBL GTO75.4

Power Output 104 watts RMS x 4 channel at 4 ohms
and ≤ 1% THD + N

284 watts RMS x 2 channel at 4 ohms,

14.4V supply and ≤1% THD + N

Signal-to-Noise Ratio 80 dBA (reference 1 watt into 4 ohms)

Dynamic Power 80 dBA (reference 1 watt into 4 ohms)

Effective Damping Factor 6.384 at 4 ohms

Frequency Response (-3dB) 10Hz - 83kHz

Maximum Input Signal 5.8V

Maximum Sensitivity 230 mV

Output Regulation .069 dB at 4 ohms

Dimensions (H x W x D) 2-3/8" x 15-1/8" x 12-5/16"

What type of music you listen?

any type of music... but definitely not those noisy 1... ehehhe...

Power Output 104 watts RMS x 4 channel at 4 ohms
and ≤ 1% THD + N

284 watts RMS x 2 channel at 4 ohms,

14.4V supply and ≤1% THD + N

The output provided here is peak right? So I take it normal output is 52w watts RMS x 4ch @ 4ohms.
So what speaker you matching this amp with? If possible like to know the speaker spec.

To my POV, alternator doesn't consistently hit
14.4v.typically it fluctuates between 12-13v.

So this amp gonna use on 4 component speaker or 2 component speaker and woofer(1 or 2)?

it's RMS...................the lowest rms produce when at 12v is 75 x 4 @ 4ohm

huh... from 104 w rms drop to 75 w rms liao.... confusing man.... erm, goin to use it for mb quart pce 216.

read the spec...it's 105 rms @ 14.4v
75rms is the lowest working rmx...which is @ 12v

usually car are always running at 13.5-13.8 when engine running....and 12.4 when engine off....so u should get about atleast 85 when engine running and around 75-80 when engine off....btw, ur bat cant last long if u turn it loud when engine off

to add on howie's explaination... all this is calculated with no output loss being calculated... if the amp heats up... then the power output will be even lower due to the loss to become heat... which i think is impossible to calculate...

cheers...

i see i see.... now i get the picture...

i am a newbie in this ICE thing, in the process of buying my 1st amp... there are so many brand in the market, really don't want to buy sth wrong that make me regret and my pocket as well.... hehehe....
