Well, no.. if an amp is rated at 1500 @ 1ohm, it will push the 1500 to both your subs since you wired the subs to 1ohm, so each sub is getting 750rms. Your subs won't blow from an extra 150rms each. I wouldn't give the L5s more than 800rms before they start heating up. I know L7s can take abuse, but not sure on the L5s. With the budget you specified, the manufacturers i gave u should fit that budget. Sundown and Audioque makes amps with clean signal. Hifonics might do rated, but with a dirty signal.. but i wouldn't count on that blowing your subs. Hifonics are great budget amps. Check the classifieds in this thread. Lots of amps for sale for super cheap. You wanna find an amp thats rated anywhere between 1500-1600 at 1ohm. The reason i say this is not because i want you to push 800rms to each woofer, but with various calculations, box rise, voltage drops, your not gonna actually see the 1500 from the amp, you will see more like 1100-1200. So to compensate for that lost, you get a bigger amp. Otherwise, you can wire ur amp to .5ohm load, reduce box rise, etc. but thats a whole another story thats not a beginner's route.
