Your amp can't handle 2 ohms bridged only 4 ohms bridged so just keep it on one channel and it should be fine

What other MTX Thunder amplifier can i hook up with a MTX Thunder 6152 amplifier??


Not sure what you are trying to do, but you don't hook up one amplifier to another. You can pick any brand or model amp to drive other speakers than the ones that you are driving with the 6152. Just consider the power needed to push the speakers at the impedance they are rated(and hooked up)at. Look at the owners manual to determine if you need another amp. Hope that helps a little.

It seems my pioneer prs x720 won't ground out to my frame on my car, i have the power 12v wire connected striaght to the battery. Would it be the fuse on that wire? or would it be just because it's not...


the ground is the most important part of a car system. you should always ground directly to the frame and on a piece of bare clean metal...sand thepaint off if necessary. if not that check the fuse on the power wire if its a glass tube fuse it may have abad connection tht you cannot see under one of the end caps. go with a maxi or anl fuse!

Can i bridge this hifonics amp


If you don't know if the amp is bridgeable, then I wouldnt do it. It could already be bridged internally and bridgeing it through the speaker terminals could be disatrous, i.e. the infamous blue smoke of death. The amp looks like a 2 channel amp fromt he pic and you have two speakers you are trying to power with it. So the safest bet would be to just unbridge your speakers and hook them each up to the amp as normal. No blue smoke. Good luck!

The specs I read on the Pioneer site say the amp is not 1 ohm stable, so keep that in mind.

It partially depends on the impedance of each voice coil on the DVC subs. If they are dual 4 ohm, and you connect the DVCs in parallel ("+"s together, "-"s together), you could run a sub on each channel of the amp(s). This would put about 200W on each sub.

The other option is to still tie the dual 4 ohm voice coils in parallel, tie 2 subs in series (one "+" to the other "-"), and bridge the two channels of the amp (aka put them in parallel). But this, also, would be about 200W on each sub.

Things get different if the subs have dual 2 ohm, 3 ohm, or 8 ohm voice coils.

If the subs are dual 4 ohm voice coils, you could hook the DVC's of each sub in parallel ("+"'s together, "-"'s together) making each sub essentially 2 ohms. Then connect one sub to each channel of the amps. This will put about 200W on each sub.
