Both amps need to be wired with the proper wire gage. The 700.5 should be wired with 4 ga for both power and ground. The 450.2 needs to be wired with 4 ga also. Any less for either amp and you can run into thermal problems due to voltage sag.
Radio EQ settings should be set to flat, or as close to flat as possible. excessive BASS and TREBLE adjustment just makes amps work harder. If you find yourself adding lots of EQ to your settings, it points to deficiencies of speaker selection, or a bad understanding of what music really ssounds like.
Similarly, BASS BOOST on an amplifer should not be used excessively. If you find you have the BASS BOOST on any sub amp more than about 40% up, you likely need a larger amp or more woofers. BASS BOOST on full range channels should usually be totally off.
Batteries shuold be fully charged. Too often a system behaves badly due to no more than a battery being depleted. Check the voltage at the amp with the system playing at a reasonably loud level. If it is sagging to 11 or lower, you have a dead battery.
These are common things to start with...
