I'm running out of space in the back of the seats to mount my sub amp, and I was wondering if i could actually mount it on top of my sub mdf box as I heard some of my friends say.. just trying to get a sanity check here.

Also, my sub seems to be a little power, I'm using a distribution block right now.. would anything be wrong with this set-up?

 

Many people have done it successfully for years... but you want to make sure your box is mounted rather than loose in the trunk. Do NOT screw into the gas tank (forward of the spare, between the wheel wells).

Not sure what you are saying here. Check the voltage across your amp power and ground terminals while your system is playing and the lights are on. If you have a low voltage issue I'd suspect the ground terminal first.

 

my stereo installer made a custom wall behind the rear seats to mount my amps.

 

 

how hard is it to create a custom wall? And what do you make it out of?

And for the ground.. im using a distribution block for it.. bad?

 

How are ya at sawing wood into shapes? And then carpeting it?



Not neccesarily... your voltmeter is the judge, not us.

 

Post a picture, or describe it some more..

 

pls excuse my ignorance once again, but for the voltimeter what am i measuring exactly.. the positive, ground of the amp and how many volts should be flowing through..?

 

When voltage travels from the battery to your amp, it decreases some amount due to the electrical resistance of the wire.

You are asking us if your connection means are OK. The only two criteria for answering that question are 1) Safety, and 2) low resistance.

The best way to decide if you have resistance is to take a voltmeter and measure across the + and - terminals of your battery, and then of your amp (PS if your voltmeter is set to "current", when you do this the fuse pops or smoke comes out of it).

If your battery shows 13.3 Volts, for instance, that's in the normal range. You amp should show close to that (above 12.5 at least with nothing on, but optimally higher/closer to battery voltage.) If your amp shows more than one volt lower than your battery, you have a connection problem somewhere.

You should also do this test with your car running and your system playing loud... but only if you have a reason to think that your amp is crapping out.
