Ive got a kenwood KAC7252 amp and it looks like i fried my subwoofer by mistake..

I need a new sub. any1 knows which should be a good one.. i dont understand the RMS or peak power thingies too much but my amp is 1000Watt, do i need a ssub 1000watt or more??


some amp specs
1,000 Watts max power
170 Watts x 2 max (4 ohms) RMS
250 Watts x 2 (2 ohms) RMS

 

Hi Underworld

Ok first thing i'd say is to not to take too much notice of peak power values etc

RMS is the figure you should be looking at, and in this case you would need a speaker with a RMS power handling of at least 170watts @ 4 ohm or a RMS power handling of at least 250watts @ 2 ohm per channel for you amp.

As you lower the resistance the wattage goes up according to Ohms law hence the extra watts available at 2 ohms as opposed to 4 .

Also if you bridge the two channels into one ( which would be ideal for a sub) the output would also be increased.

I'm not familiar with the amp but from what I can see online it appears to be approx 500watts x 1 @ 4ohms

so that being the case for a single sub running off both channels bridged make sure its at least 500watts RMS @ 4 ohms

or for 2 smaller Subs (running off both channels seperately ) they should be rated at least 170 watts RMS @ 4 ohms each


hope this helps

You could also go for a dual 4ohm sub and run it parrelel to get your 2ohm load which will give you some nice bass
