Well ive had the 1508's for a couple months now and they just dont satisfy me anymore. I miss the lows that i got from my type X 12s i had in my cavalier. I had each type x hooked up to an alpine mrd 1005. but it was on a stock alt so i know i wasnt gettin the full 2000 watts. I only have one of the mrd 1005's now and i wanna know if theres any setup (preferably a single 15 but id do 2 12's again if i had to) runnin off of 1000watts that would give me close to the same output as my type x's did.
