yesturday my friend was complaining his subs were cutting out, so we took them out of his box, completely rewired them to 4ohm load, put em back in

he said the problem is still happening, and now im thinking it's his amp?

His subs are SVC 4ohm MTX thunder 4500 12"s in a sealed enclosure, and his amp is an 800w kenwood amp, 2 chnl.

the amp isnt capible of 2ohm load, which he previously had them as 2 ohms (only for a few hours till i told him his amp isnt 2ohm stable).

could he have ruined his amp? its only at a high volume, the subs cut out at any random time

thnx in advance for any help.

hm, just did a lookup on his amp and it appears to be 2ohm stable, but even at 2 ohms it was cutting out.

the subs were no where near their limit also.

Ugh.... you had better be a little more accurate on the wiring.

2 ohm mono and 4 ohm stereo I presume.

Cause it ain't 4 ohm mono that's not possible.

Provided there are 2 subs....

it soudns liek you have a bad ground or wire somewhere. tahts what it usualy is when you have a problem with them playing at low volumes then cutting out at higher volumes. the voltage drop shuts the amp off

Wiring is fine, i know that for a fact

now im positive it's his ground, i had a ground issue when i hooked up my amp and it wouldnt even turn on, volts went from 14.3 to 4.2 or so, so i fixed it.
