[QUOTE="quackhead, post: 7776113, member: 573547"] [B]you have two 4 ohm subs. if you wire them parallel to one amp channel, the amp will "SEE" a 2 ohm load [/B]Your KW is not rated to be stable at 2 ohms into 1 channel ( bridged to 1ch/mono).. The 8105D amp you posted a link to is rated 500w rms at 2 ohms...wire both subs to the amp parallel and it will push them with 500 watts rms, or 250 watts rms PER sub. You can wire 10 speakers to one amp channel, as long as they are wired correctly and present the correct ohm load (impedance) to that channel..you would just take the rms wattage at the wired impedance and divide that by the number of speakers wired. ex. 10 subs wired parallel/series to a single 1000watt rms channel = 100w rms per sub. Brother, you really have to look past the "MAX" ratings on amplifiers. you have two 4 ohm subs wired one to each channel. the power rating for that map is 170 w / ch.on that load. The amp may be able to provide more than that during transient peaks, but when you are listening to music at moderate levels, the power output is going to be fluctuating in that 170 watt range. The Max is an idea of headroom on the amp. To be fair to you and your subs, look at RMS ratings. Are you a die hard Kenwood fan? [/QUOTE]
