[stay_high 10+ year member]

Trying to bridge my kenwood kac 7205 to my 12 inch kicker cvr. The sub is currently just running off one channel and getting 250 watts rms. Its a 400 watt sub so im gona bridge it so the sub can get full power. Is this really all i need to do? i dont have to do anything to the wires pluged into the sub i can just leave em the way they are? Thanks

you cannot run that sub bridged to that amp.

Per the Kenwood Site

KAC-7205

Performance Series Stereo/Bridgeable Power Amplifier

Specifications

• CEA Rated: 170W X 2 (1.0% THD+N) (4Ohm/2Ch)

• 250 Watts x 2 (2 ohm)/500 Watts x 1 (4 Ohm Bridged)

• High Quality Speaker Level Input

• Blue Illumination

• High-pass (12 dB per octave) and low-pass (24 dB per octave) filters variable from 50 to 200 Hz

• Variable Bass Boost Control(0-18 dB at 40 Hz)

• Cooling Fan

That amp cannot handle a 2 ohm Bridged Load

You need either a second sub or a different amp.

Im sure that some of us told you to take the sub out of the box and check the coils. I guess you never did that and listened to the wrong person

Is it hard to take it out of the box? and what exactly would i be looking for when i got it out?

Get a screwdriver and take the sub out.. The coil config should be on the motor somewhere. It will say 2+2 or 4+4 or something like that

his sub is a dual 2... you can wire it, following the schematic I posted in your other thread, to 4 ohms, and then bridge it to your amp. this is all in your previous thread

sorry i guess i didnt subscribe to it because its nnot there. But that youtube video is that all i need to do? Cuz im go outside right now and do that if it is

 

[mast240 10+ year member]

that is the last part of it... you need to make sure that your sub is wired correctly, to four ohms, like the schematic in your previous post shows... if your not subscribed, then you can click on your user name on this post, and then click "view thread posts" from the drop down... it will be in there

checking to make sure your sub is wired properly is the most important step tho, cuz if you don't, and its wired down to 1 ohm, you could damage, or even destroy your amp

 

[stay_high 10+ year member]

okay so im gona email the ebay seller and ask him wether its 4 ohm or 2 ohms since no one seems to know. What exactly should i ask?

Take the **** sub out of the box... Get a freaking screw driver and take 8 screws out around the sub and freaking look at it! Really man if you cant do something that simple you are in the wrong hobby
