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.

I have a system installed and i have mtx speakers plus mtx subwoofers i want to know how could i take the bass of the speakers because it sounds horrible when loud

if you turn the bass setting in your radio down it will take the bass out, but may take some of the bass out of the subs as well, if this occurs and you still are not satified, you either have to get a car receiver with a non fading subwoofer preout, or you could get bass blockers for all the speakers you dont want the bass in

How do i wire up my mtx 15 5500 sub woofer dual voice coil any one know i have tried several ways

there are several ways, it all depends on the bass response you want, and with that, it also changes the ohms in the amp. i'm going to give you seval ways to hook them up. if you are running more than one just follow these steps per sub. the first one is if your sub is dual 2 ohm. Wiring Option #2

2 MTX Thunder Problem.. Bridging?

Is there a option on the chanels that say ''Bridged''? If so, you can hook the subs up in parellel or series to get different ohm loads. Usually the lower ohms, the more power amp puts out. Those subs can handle 225 watts RMS whitch means the power it can handle constantly. If the amp gives more than 225 watts RMs, you could be at risk of blowing the sub. If you could give me the model # of the amp, I can be of more help.

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
