Hi,
I have a Pionner DEH 5650 i think and I am runnng two sets of splits and a sub (JBL powered amp) and an MTX amp...power split by a power splitter...

what happens is if i gain the MTX amp (runs 4 splits) high the subs volume decreases sharply as if not enough power is going into it or something...if i lower gain on MTX i am able to get decent sound off the sub...what am I to do ?? i cant fullly utilize the splits or the sub due to this

thanks for the help

 

Ok let me first ask a few questions. What size wiring are you using? What size are are you amps? How high are are setting the gains? Are you sure when your turning down the components (I am assuming what you mean but "splits") your no just hearing the bass more? Have you tried measuring the voltage across the power terminals on your amps? Im assuming a power splitter is a fuse block?

 

Hi,
I am using one 8 GA cable coming from the battery which splits into two 8 GA cable via a copper block power splitter. The AMP i am using is a MTX 404 amp and a 100W RMS JBL powered SUB....

I am turning the gains not even half way up man....and yeh component speakers

thanks for any help

 

OK well im not an expert but i have some suggestions. First is to run 4 guage to a fused block then run the two 8 guages out of the fuse block into the amps. You need to have the fuses to protect the 8 guage wire coming out of the fuse block because if there is a spike the 4 guage may handle it fine but a fuse will protect the 8 guage from problems. This will also give you the ability to go to bigger amps. Second is that it really seems like the sub is underpowered. It may be when your turning it up the sub amp is begining to hit its max and will no longer get louder.

Just to clarify when you turn the vol up on the deck do both the components and sub come up at the right volume? Or are you saying when you turn the gains up on the amps then you are having the problem? Have you checked to make sure your grounds are tight and on bare metal?
