I need the schematics to wire the TR-9500 car subwoofer box for a friend who works as an manager/accounting got there fingers on it. Get my drift? Help! Just do it yourself

In order to sound good, there are a lot of specifications that have to be considered when getting a speaker enclosure. You have to know the size, depth, displacement, SPL and other factors on the speaker, then you have to match it to the height, width, depth and porting of the box. So if this was not done, you will have muddy sounding audio.

ok..I just did alot of research on these. They are made in china and cost around $30. ..if you get them in china. I can't find any actual retailers anywhere...except for guys selling them out of the backs of vans. I guess a few street **** have scams going on where they buy hundreds of these things, then mark them up and sell them for $200-$800 on the street. That being said, almost everyone that bought them said they were actually good speakers.

2 15s in a ported box. will sound great

i would say its worth about $400 - $500. depending on the condition of the box plexy glass and subwoofers.

Open the sub box, and check to make sure the sub wires didn't become disconnected. You should need only a screwdriver.

the subs cant handle the wattage coming from the amp

Those terminals are the power to the module. The tr should be the 24v (hot) line coming from the transformer. The tr/th is the common from the transformer and the th is the 24v line coming back from the t-stat. So tr stands for transformer. the th stands for thermostat. And the th/tr is the common.
I know you ask for schematics but I felt that I could easily explain it to you. It really isn't all that hard. In some cases the tr does not need to be hookup. if you only have two wires there than just hookup the th/tr and the th and it will work.

if ur amp is not 2 ohm stable and ur sub is wired in 2 ohm ur amp will fry.go to crutchfield.com type in wiring subwoofers u can get ideas there

u need 2 find out the ohms on the speakers 1st 2 c if the amp u want can hander ur speakers

Why would you hook up 4000 watt amp to a speaker that has only 1000 watts. Try a 800 watt amp instead unless you just dont want the spealers.
