Subwoofer question

I got the wires and everything ran thru my CL, but I want to confirm this before i do anything.

If i use a 1000w max 460w RMS amp with a 12" round solobaric 300w RMS 600w peak, would it blow it? I'm scared to use it due to the fact that I might blow the sub. Someone told me that it was too much power. Anyone?

Thanks

Yes, not only is that above the rating of the sub, subs always overrate. This will almost certainly blow your sub if you crank it a couple times.

Thank you so much man...cuz right now I have 2 infinity reference 12" 300w rms 1200w peak. I was gonna trade both for my friend's solobaric, but he questioned whether it would blow. But for some reason I can't run both my subs at the same time, cuz the amp does 150w in 2 channels! It's so weak! Well thanks a lot 97Cl22!

True but even the RMS power of the amp in question is above the recommend stats. Running this setup will be basically chancing it every time you turn on the system and the subs hit. Solabarics rock, but they are still blowable. Go get an 800W peak bridgable amp, then that bitch'll slam and it'll be safe. You could probably ebay on for like 200 bucks, though i don't price amps on ebay often so i could be wrong.

Quit talking about peak power. That is for sissys. We have an amp in the shop (Crown MA5002) that is rated around 2000 watts per channel at 4 ohms that can output near 4 times that if allowed reach IOC (IE clipping).

And NO, you won't blow it after bumping a few times unless you clip the amp. That will be your problem - knowing when to stop. It's also very possible to blow a sub with too small of an amp given the amp is very well made. You clip the amp, it sends out some nasty square waves that are 2x, 3x the power and boom bye bye sub. I'd rather have the larger amp and be careful. More power is better than clipped power.

like the post before me peak is a marketing scam. only rms matters. its better to have a amp with more power the the sub is rated for because clipping kills subs. you just have to get your gains properly matched. for this just turn your deck to the highest you will ever turn it while listening then turn up the gain on your subamp till you hear a little distorsion the turn the gain down about 1/8th of an inch. im currentl running a single idmax (1000watts rms) with bd1500.1 (1500+watts rms) havent blown it yet and its been in my cl for 6 months and i do listen a very high volume.

for as long as i have had systems, i have always overpowered my subs. i have also never had to turn my amp gain to its max point. i have never blown any sub in any of my setups.

its not the extra wattage that blows, its usally the lack of, that blows,,,,...... and distortion and clipping.

That amp is probablly overrated...

Im running a 3000watt class-d Boss amp to 2 Kicker CVR's

Theyre rated at what.. 400-600 RMS each?

Supposdlly my amp is putting out 1200 watts to each sub.. rms

Is it...? Probablly not.. but it still hits hard as fuck, you don't drive around blasting your system all day and if you do, then you still probablly wont have to worry =\

sorry to say but your boss amp is well over rated and probably isnt even close to that rating

What you need to do is:

1. Hook all the shit up, turn sub amp ALL THE WAY DOWN before you ever hook it up - don't want any suprises.
2. Play a CD with lots of bass. Turn your head unit up as loud as you will ever get it, actually a tad louder. Make sure your sub control is all the way up if you have one (on the headunit, if you have a remote gain, see #3).
3. SLOWLY turn the sub amp gain up until it either A) pounds the hell outa you so you don't want it any louder or B) it starts making a weird noise (squeak, sounds bad, etc) and then turn it down until that stops.

couldn't have said it better. I have the square solos that are rated at 750 watts rms, and I have 1000 watts on them!

A friend of mine had a 1200 watt amp on an 8" L7 in a ported box. It was damn loud in his lil Eclipse. Peeps wanted to know if he had two 10s or two 12s. Amp kept the sub very tight and controlled. He had the gain around 1/3rd the way up.

Also, more power is cleaner power. As proaudio said, always overpower, rather than underpower. Remember this too: you can blow your subs by underpowering them. Just use the steps that proaudio listed in order to correctly set the gains (typically easiest when done with two people). Lastly, use as large of a power line as you can afford. I would suggest either a 4 guage or a 2 guage power cable.

Nah, not for 460 watts. 4ga is fine for even 1000 watts. Unless your wire is undersized, the difference in impedence btwn larger sizes won't make any difference on your setup. Just make sure your ground is very good.

is that 460 at 1 ohm? because with one kicker you'll be running at two.
