Re: icbm 779

If there is significantly less bass even though the speakers are moving approximately the same as before, you may have one speaker wired out of phase. Disconnect one speaker. If the bass increases, double-check your wiring.

Mtx mxa 6001 amp cant get it to produce good bass using mtx 5500 subs running a 2ohm load

You seem to have everything in spec. check your crossover points and your speaker wiring. subs may be playing out of phase.
A huge factor is subwoofer enclosure ...if the enclosure is not in spec with sub requirements the subs will not peform great.

Well it could be that your ears just got used to the bass. It happend to me after about a week of haveing my subs. And make sure that your power wire hasnt got melted somewhere. also that you have good ground.

You may have a defective speaker or a wiring fault. Disconnect the speaker from the amp and measure the resistance across the speaker wires. The resistance should be near the rated impedance of the speaker.

Subs will go off the wall with bass, but not in tune with music.

hi, first disconnect the rca input, then switch on headunit and if the amp produces a constant bass thump it then means it has an internal fault. if the amp idles quietly then replace the rca cable, or try connecting the headunit lineout feed directly to the bass amp, in this way you cud find out if your fault is coming from the headunit or the equaliser. cheers
