sub preamp outs?

Hey guys.. i just completed my very first system 2 days ago.. i just ran one sub outta my one amp.. i am planning on expanding when i go to collage.. I have a cdx-m8805X deck with front and rear preamps and also sub preamps.. i did try it outta teh sub preamps and it didn't work (this is b4 we got the system fully working) *i may just take it apart tomarrow and try it*.. but i just wanna make sure that it should work.. since im just running my sub outta this i thought that would be awesome to do.. on the deck with the sub preamps they are not labeld poss/neg, they are both black.. so i guess ill just plug them in and if it dont work switch it around? Ill try this out tomarrow and write back but i just wanna make sure that i have the correct idea here!! Thanks

Alright man.. thanks a lot.. i will test it out tomarrow morning b4 i go to hockey and poker.. i will post back later on and let u know how it goes.. ALSO: another question.. i noticed while driving at night that my ac/fan speed lights were out/dim, and half of the defrost/vent selection knob was out/dim.. the others were all fine tho.. Any ideas? PS: 01 neon with just a candian tire motormaster matched battery.. and stock alternator!! Thanks

Alright.. its working now.. awesome.. now for my next question about the lights? anyone have an idea (^^^^^^ one post b4 this one) Thanks a lot!

Sounds like you blew a fuse.  I bet you didn't disconnect your battery before you installed the HU.  Check all fuses under the dash and in the engine compartment and replace any that are blown.Support the12volt.com

alright.. im gonna check thoes later tonite or tomarrow.. i know where the fuse panal is inside the car but am not possitive where the panal under the hood is! this is an 01 neon!! Thanks

Its probably because its a dodge, heh just kiddin. have fun taking panels off if it wasnt a fuse tho. good luck with everything, and learn to not use as many a's in replacement of other vowels . I normally unplug the battery before doing any electrical work. Even when just doing speakers or something, better safe then sorry I guess.99 Blazer LT.   Yellow Top. Big 3.

ok.. i checked the fuse panal inside the car and all fuses looked good.. i need to know where the fusebox under the hood is..

ok i may be a bit retarded..lol.. found the fuse box and am going to check them later today!
