Is rated for 50-400 watts RMS. That is the "constant" power it will accept from an amp. The Peak rating is 1,400 watts. You want an amp that has an RMS rating somewhere in there, probably towards the higher end of the range, without exceeding the range.
For example, this amp: http://www.crutchfield.com/p_777M135...34#details-tab
Has an RMS rating of 210 Watts, and a peak of 750 watts. So based on watts, it would be fine. I don't know enough about ohms and all of the wiring differences available, so wait on someone else to come along with more knowledge on that. But whenever I have run a pair of subs, it was a 2-channel amp, not a mono one like the one I linked. Separate wires to each sub from the amp.
What you read is true. If you had 2 400 watt subs, they would need 800 watts together, so you would need a 800 watt amp.
If you can find out the RMS rating of the sub you have and the ohm rating, and then find the RMS power of the amp you have, we could tell you if adding another sub would work or not.
Sorry for not replying for a couple days, been outta town. I currently have 2 subwoofers running off the 600 watt amp. It is a 2 channel amp. Damn thing keeps going off on me. Theres a red "protectant" light that comes on, and the amp/subs stop working.
Call me stupid, but im assuming its too much for the amp? Probably going to have to upgrade. Any ideas? Any suggestions on amps? Maybe ill post some pics up to see if theres any obvious triggers for why this happens. When they work, they work awesome. No problems, until it all goes down hill....lol
You seem to be a little lost. A few tips - legacy brand car audio is about the worst you can buy. That 600 watts is probably more like 150 watts. They hyper-inflate their power numbers to sell them. Legacy is one of the classic "flea market" companies. Secondly, bridgeable means you are combining both of the channels to a mono channel. You can run AS MANY subs as you want off of 1 channel as long as the impedance is correct. However each sub will get less power the more you add.
Trust me, that amp is probably on its way out, their quality is bottom of the barrel. The whole wattage thing isnt very well understood, I have a 1200 watt sub, I can run it all day with 200 watts... it just wont be very loud.
The sub you listed right there is perfect for that amp. Its a single 4 ohm voice coil which is what a 2 channel amp wants when running mono. If you want louder bass, you are going to have to upgrade, perhaps buy a second pioneer and get a quality mono amp...
Again, if they are both 4 ohm subs and you had them hooked up in parallel bridged on the amp, the impedance was too low for the amp hooked up that way. If you hooked one to one channel and the other to the other channel, the impedance would be ok, and it would probably work, just not be very loud. But I agree, I've never heard of American legacy amps.
My vote is always Rockford fosgate, but I think JL is another top one, and ken wood and pioneer ain't bad. Look for an amp that can do 600 watts at a 2 ohm load. A mono amp would be cheaper also.
