Help with connections

[freewayrandy 10+ year member]

Please pardon my ignorance as this is my very first install of an amp & sub. Going in a C-3 'Vette. (minimal room) I acquired from a friend a Coustic 160 watt/30 RMS

2 ch amp. (20 bucks, thought I couldn't pass it up) I bought an 8" sub 300 watt peak/150 W RMS/4 ohm (only one I could find shallow enough for my mounting location) What I need to know is the proper wiring of the sub to the amp. Deeply appreciate any assistance.

to bridge an amp connect the + on your sub to the + on one of your amplifier channels. then connect the - on your sub to the - on the amplifiers second channel. most amps only run bridged at 4ohms. so to do this your sub has to be an SVC 4ohm sub.

It's a DVC 4 ohm. Am I screwed?

this manual has a diagram on page 5

if replacing the sub isnt an option you could run the sub at 2 ohm to a single channel on your amp, it just wont be getting as much power.

OK, thanks for that. Found this on another thread.....just wondering....are they showing one red wire from sub + going to amp left + then one black wire from sub - going to amp left + ? The only thing confusing me is they are not showing terminal markings on the amp! Unless they've been the same forever (my amp is vintage '89) outside terminals are both + ?

that diagram will give you an 8 ohm load. if you are going to run the dvc4 sub on this amp then you want a 2ohm load for as much power as possible(provided your amp is 2 ohm stable). http://www.caraudio.com/forum/showthread.php?t=31984

run the + and - to just one of the channels on the amp.
