How to install a 4 channel amp to HU with only 2 Channel preamp

**ckwu** · 11-23-2009, 04:20 PM

I have a Kenwood KDC-MP232 which only have 2 RCA output, and a Formula-X FX-450 800W with 4 channel input and 2 channel ouput, and a Boss D10F sub-woofer. Don't really know are they all compatible or how to wire them up together. All helps is really appreciated.

you should be able to hook up the amp using 2 rcas off the deck, but i cannot seem to find any specs on the amp, so i can't say what the best way to hook the amp and sub together would be. it is very possible that the amp is not 2 ohm stable, so hooking it incorrectly could damage the sub or amp.

and just fyi: this is a car computer forum, so most answers will be heavily biased against non-computer controlled/integrated setups...

check the sticky at the top of the car audio section for a listing of car audio forums.

not neccesarily-- from what i get from his vague post, it seems he only wants to power the sub, not any other speakers-- and depending on how he hooks it up, he will really only need 1 or 2 rcas-- 1 if he can bridg the channels for sub output, and 2 if he can run a stereo input.

i was hoping he would repost with some more specs on the amp, or setup, but that doesn't seem to have happened...
