Question about Kicker CVR12 Car Subwoofer
Ok i have a pyramid pb-772 its 300 watts max 150 rms its two channels im wondering can it be bridged its kinda old but not to old i need to power a kicker impulse the stillwater design 12"
I cant find a whole lot of information on that amp or any other older pyramid as they arent exactly the most popular amp but just applying what i know about amplifiers in my opinion i think the amp is more than likely only stable @ 4ohm when it is bridged and @ 2ohm in stereo (using both channels) so yes you should be more than likely able to bridge it because the impulse only came in 4 and 8 ohm voice coils and i dont think they made a dvc impulse so check the sub paperwork . if you dont have the paperwork look at the sub and check for it or get the model number and ill be able to tell you what the ohm rating is on it and remember if u decide to bridge it be carefull not to turn the gain up like it is the volume controll. it should typically be set under half way but you maybe ok going up to 3/4 but i am not sure how it will sound @ that level so if its not loud enough after that you should consider getting a slightly larger amp ( a good rule of thumb that i have found is that the subs rms specification should only be 2/3 of the totall rated rms output at the ohm load that the speakers or speaker are as this should allow u all the spl you want without really heating up your amp and if u ever buy new subwoofers you have more power left in the amps output capabilities because when u buy new subs it is usually to upgade in quality which usually requires more wattage and youll have it
sorry my answer is so long . if u have any problems pls feel free ask me
and again you should be very capable of bridging it just find out the ohm load for the impulses voice coil HOPEFULLY it is an 8 ohn because when bridging an amp it halves the ohm rating on the sub
sorry such a long answer but i just wanted to cover as much as i could in case you have any problems if u have wiring questions or want to see a wiring chart go to www.the12volt.com for all kinds of excellent information charts wiring wizards and here is the link to the subwoofer wiring wizard
thanks for letting me try to help out and god bless

Hi Trim God,
I do not reccommend that you push the Pioneer speakers over 100 watts. The jenson will already drown the car with bass through your pioneers so much you will want to turn off the bass boost when playing some low bass hip hop songs. It changes from one venue of song to another, so I just keep the jenson bass boost off and use my head unit to adjsut the sound to fit my listening prefences. I am telling you man, you will be blown away . Hook up the pioneers straight to the Channels,. do not bridge. I put Subs in my truck though. I used the Pass output to send the audio to me Jenson 2 Channel 600W amp. I drive one 10 inch enclosed JBL Class A/B Sub. I bridged the output of the 600 W amp to the 10 inch sub in my Z28. The pioneers never get drowned out. I did smoke my 2 channel Amp one time. and also took out a MTD 10inch sub. I am talk shooting flames and smoked the whole car up. I think if you bride the XA4150 to the pioneers, you will have the flaming smoke problem in no time.
