A diamond , memphis, 1000 rms amp on them would be nice for the same $$ as a 500/1

1000RMS is too much for 2x300RMS subs.

Id rather underpower my subs than to overpowering em just waiting to blow em.

[EDIT] thats what u meant right???//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

I think i will BLOW my subs if i went with a JL 1000/1 Amp.

Its only rated 300RMS.

//content.invisioncic.com/y282845/emoticons/eyebrow.gif.fe2c18d8720fe8c7eaed347b21ea05a5.gif .. ok then think what you will .. Ive seen 500+ rms daily on the 12w3 v1's from 5 yrs ago rated at250 rms.... And if you think the power is too much for them u turn the gains down.. But what would i know right? Ive only seen a dozen or so 2 w3 setups w 1k power and used to sell jl //content.invisioncic.com/y282845/emoticons/rolleyes.gif.c1fef805e9d1464d377451cd5bc18bfb.gif

I know that you are correct with that assumption IF you take the subs to task and not allow them to cool. And turning the gain down on a amp does not magically make it produce any less power either. If you think it does, great, here is a hat, pull a rabbit out of it.

lol ... no man...//content.invisioncic.com/y282845/emoticons/eyebrow.gif.fe2c18d8720fe8c7eaed347b21ea05a5.gif i know its not a volume knob, but less voltage means less clipping, less of a chance for the coils to heat up, less of a chance to blow ur equiptment... Ive had at least minimum power on every system ive ever had, if you use common sense you'll be fine and fyi... A 1000rmsto those subs is not what they'll actually be getting.. try 800 or so ,.. Now do the math

Did not mean to offend you ! As i said, Im still new to this. I already ordered my amp on ebay, and the 1000/1 is too expensive for my budget, so the 500/1 is the next step down.

The 500/1 will supply enough power for some incredible thumpage no?

to the origonal poster ... This is the amp i see on many dual 500 rms/per sub setups.. Which i have 2 of ... Just something to think about...And also everytime i OVERpower a sub due to rating ive never had a problem, and imo... Its pretty tough to blow a sub from a little more than rated power / opposed to underpowering ... So.. theres my rabbit trick

Yea the 500/1 is a great amp.. Being regulated is also nice to keep ur power up.. They put around 650 rms on every test ive seen on them... i didnt know you already got it, but yea in theright enclosure they'll wang pretty hard.. I have a 1000/1 on my 12w7.. Love the sub and the amp

Um, no. Sorry go back to start and do not pass go. Less voltage does not mean less clipping. Less clipping means that the gain is set properly and the cd player is not sending out a clipped signal in the first place. If your cd player has a high output voltage, the amplifier can be driven to full output with the gain set at a relatively low setting. If the cd player has a low output voltage, then the amplifier will drive to full output at a relatively higher gain setting. Any incorrect gain setting be it with a low or high input voltage will send an amplifier into clipping. A speaker can indeed play a clipped signal all day long provided the speaker can dissipate the excess heat generated by the clipped signal. Break the thermal barrier on the sub, clipped signal or not, and the sub will fail.

Yes the 500/1 will provide some good lb.age for you. Good bass response is all about the box, pour your time and efforts into a proper sub box for the application. Learn how to set the gain properly and realize that if you want this system to play loud and proud and annoy everyone (like me - I hate people that do this), you MUST allow the subs to cool or you will be in the market for new subs in short order as well.

You have pulled a dead rabbit out of the hat. If it is more dangerous to underpower a speaker, why is it that everyone's coax's have not died a horrible smelly death? No offence intended in my posts either, take it as something to learn. I continue to learn in this industry every single day. Even after 20 years in the trenches, vehicle and equipment change, I must continue to learn and change with them.

I'm missing ur point .. So ur trying to tell me that if by using a dmm ur amp will clip more than it would at the exact setting?/ im not following you, nor should i if your telling thisguy overpowering his sub by 1-200 watts is gonna kill them.. Like i said.. Ive run 2x power in 90% of my setups... Never had a problem.. Enclosure is a big thing as well when deciding how much power to run... Ive seen idiots blow w6's off a 500/1and ive also seen single10 w6' on a single 1000/1.. So to each his own

a 500/1 is fine for thoes woofers. you dont have to get somthing you dont need. unless you plan to up grade the woofers etc.

There has been so many arguments in here about underpowering/overpowering subs, that link reminded me of it and made me lol //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Not following is what is going on.

You can indeed overpower a speaker and as long as you allow it to cool, thus not break the thermal barrier of it's design specifications, indeed it will be fine. Break the barrier though and you will be buying new subs.
