i have a PPI PCX-1250 amp, and its rated at 500rms at 2ohm's, i want to buy a 15'' kicker L7, rated at 1000rms with dual 2ohm voice coils i can run my amp at 1ohm... however is this a good idea, im not sure if this amp is 1ohm stable, and wheather to do this or not??

 

If it doesn't say its 1ohm stable it probably isnt.
While it would mostliekly be ok to burp at that impedence, I wouldnt run it that low for a daily driver. The L7s come in dual 4 ohm I think.

 

Yup L7s come in dual 4ohm

Jason, were you thinking that if you dropped to 1 ohm you would be able to get the 1000 watts you need?

While there some amps that will double the power at half the impedance this is not always the case. There are many amps that will give no power increase and simply heat-up more. My advice is go with a dual 4 ohm L7; OR get a second PCX-1250 and use one amp per 2 ohm coil. That will give you the 1000wrms you want.

 

alright thanks for the help, i think i'll run the L7 at 500RMS, it'll probably still sound goood

 

yeah ofcourse it will sound good i used to have the PCX1250 and loved it , i wouldnt drop under the 1 ohm mark if i was u on that amp , go for the L7 dual 4 ohm
