MSP kenwood amp question

[Autox MSP]

does our kenwood amp come with a preamp out?? I'd like to install another sub, and make the wiring simple. Also what is the gain set at from the factory?? the sub hardly makes much bass.

I would highly suggest not using 2 differnet subs.
Also do you have an MP3 or an MSP?
Either way this should be in the audio section.
The MSP Kenwood amplifier (KAC-629S) does not have preouts to my knowledge.
