JL Audio Amp Line?

[XCivic 10+ year member]

I know they have a reputation for making good and very power efficient Subs. But how are their line of amps? I'm thinking of changing amps and was wondering about their amps.

Also can some one tell me the thing as far as amp rating/class....I've seen in mags and on the net "class A/B, A and so on" or whatever....what do they really mean. And how does this classification work or what are the qualities or features an amp needs to be considered in such classes....

Thanks

As far as I know their amps really kick ***, they are as good as their subs, anfd pretty expensive, for more information on class A,B, D, go to http://www.eatel.net/~amptech/elecdisc/

really nice page, that explains in a clear way everything about car audio electronics

hope that helps

JL amplifiers are great performers, although they are a little spendy.

To each his own, I suppose, but I stronly disagree. Although PPI make a very good amplifier, I would not compare HiFonics to JL. What features don't you like on the JL amps?? The 0.05% THD from their monoblocks, the onboard crossover, and parametric EQ or the infrasonic filter? //content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif

I agree that they(JL) are pretty pricey. But so are PPI and Hifonics amps. I already own a 6 channel PPI infact.....but the sub channel doesnt give me much control(fixed LP @ 90hz with a bass boost of +1-+18 if I remember right. Also cant use any kind of eq or x-over on the amp cause it only has a front and a rear input so even getting an EQ wont help me out....also asked PPI about they said cant do it with that setup. Dont get me wrong though it is still a very good amp. It hasnt cut off on me and I've had it for close to 2/3 years now. I just want something that gives me more control as far as X-over frequencies...so any suggestions on good amps would be great.

How much are you looking to spend?

 

[XCivic 10+ year member]

I wanna try and keep it around 350-480 range but i have seen some Alpine amps and JL amps for 280 and up? But the Range is 350-480 if possible any cheaper

so it is overrated by 233 watts, is that what you're saying?

what exactly is benching?

 

[kottonmouth 10+ year member]

it is underrated...benching means testing the amp to see what the amp actually puts out.

errr yeah that's what I meant

lol

**** that's a lot

I wish companies would rate their amps at the actual output!!!!
