Well I have a legacy amp in my car. I am on a tight budget, and for the money these amps are dam good, i wouldnt reccomend pushing subs with them but i got the 4 channel la690 1000w amp. pushing my jbl gt componet set and they get lound and clear. so loud that at half way u cant stand it its so lound. but still clear. so i say that if you are on a tight budget then yes these amps are good and they are worth every bit of the money.//content.invisioncic.com/y282845/emoticons/cool.gif.3bcaf8f141236c00f8044d07150e34f7.gif
