ok so i got a 1997 Sol, right now i got a 4 channel Kenwood in it to power my speakers in the cab. i already ran a RCA line for the subwoofer. now my friend tells me 'instead of getting 2 amps, y dont u just get a JL Audio 500/5?" now here is my question, what do u guys think? is it better to get 2 seperate amps, or 1 five channel amp and run all my audio from that one amp? (if it matters, im planning on getting a 5 farad cap no matter which one of the 2 i get )

thankis,
Carlos
