distorting sub question
i have a 10w7 in a ported box powered by a legacy predator amp. the amp is like new, but the sub i got used and has a few holes in the display cone. it sounds good at low volume, but when i turn it up anywhere past half volume the sub distorts pretty badly. my question: is this because i have a shitty amp or is the sub dieing?

Re: distorting sub question
How big are the holes? Whats the RMS output of the amp and the RMS of the sub?

Re: distorting sub question
My guess is it's the amp clipping

Re: distorting sub question
single port: 1 5/8 x 12 1/2 x 17
sub's rms is 500, amp i think is 600 (thats either rms or peak, can't figure out which one, even sent legacy an email and they won't respond, its a la968 amp), but i don't have the gain up all the way. what's clipping?

Re: distorting sub question
legacy is a crap company. really... crap. worse than sony. you're getting less than 300rms outta that amp.

Re: distorting sub question
well its a two channel, and i have it running off only one for fear of blowing the sub. 1200 bridged is the claim, think its worth it to bridge?
but yes, i need to get a better amp

Re: distorting sub question
^not before you do some research, or you'll end up throwing away all your money all over again. I don't mean what brands are good and bad. You should understand what you are buying.
a good, thorough site to research is www.bcae1.com

Re: distorting sub question
based on what ive read so far on that site, and from hooking the sub to a friends amp, it looks like the amp is clipping. running the sub off ~225w rms make the cone move a hell of a lot more.
guess ill try just a new amp first. after doing some research of course thanks for the site
