Ok just to get this out of the way:
06 Cobalt SS/SC
pioneer 7 speaker


Ok before I got my new headunit I was running factory with line converter for aftermarket subs and it sounded good. But now after putting the aftermarket headunit in I can't even turn the volume up enough to hear the aftermarket subs. Is this due to the factory amp that is in the car or something else? This isn't the first time I have install an aftermarket HU but it is as far as into a car with a factory amp in it.





Anyone?????

 

Anyone????

 

its due to the factory amp... with the new hu its getting a lot more power then before. and depending on the hu the subs are getting less or a little more power

 

So would running new wires from the headunit to the speakers resolve this?

the HU is a DEH-P980BT
and at half volume it is loud as hell!!!!

 

an amp bypass would help yes. the issue you will run into thou is the front speakers are ran off diffrent channels on the amp. so you would need a crossover for the fronts

 

what if I just ran new wires from the HU to the speakers leaving the factory amp out of it completely?

 

That would work. In fact, I would probably encourage that Richard. You'll most likely get better sound by doing that anyways.

 

thats what i was talking about. you would need some sort of crossover for the tweeters if you did that (mind you due to the molex plug in the doors your wouldnt really want to run the wires completely in the doors but just to the factory amp and wire them in after the amp)

 

the new HU has front and rear hpf settings will that due?

 

no your best bet would be to buy some actual crossovers. or rcas to use the preouts on the deck instead of speaker wires... you would either need to find a set that has the power/ground seperated or buy a normal set cut them and sorta ghetto rig it. the outer wires are ground and the inner are power

 

ok but would it be fine for now until I upgrade the rest of the speakers in the car? money is tight rite now and what crossover would you recommend?

 

whatever i guess... the cheapest thing would be just a cap for the tweeter(if you research the one you would need it might even be better then buying a random crossover but its also dangerous bc if you don't and just throw a random cap on there then **** will hit the fan). The best bet would be something designed for 2 ohm but i doubt your gonna find that

 

hmmmm............. This is starting to suck. I got to figure this out so I can get the subs hitting again. I appreciate the help.

 

if there is really that much interest i could possibly see if i can get a hold of those RCA ends im talking about... mtx makes some

 

well now that I can turn the volume up. I still am getting nothing from the subs. This is starting to **** me off. could something else be wrong?

 

possibly. did you already remove the LOC. try using it again if its still connected

 

yeah I did try that and it was the same. Nothing. I am about ready to yank it all out and start over.

 

Richard. If you're off this Friday then come to RNR. We'll be there ALL day, and I'll get Adam to look at it for you.

 

Nope I aint off on friday. I am off on saturday but I can check and see what time I go in and get back with you.

 

Well I figured out what was wrong. My amp is screwed up! Me and a buddy of mine hooked my subs to another amp and they worked great. So now I got to get another amp. This SUCKS!!!!!!!

 

huh... what kind/model is ur old amp?

 

Rockford Fosgate P300 1

 

i could get it fixed for you if youd like. 80+ shipping

 

Naw, I already got a new one coming. The one that is messed up is a Rockford Fosgate P300-1. The one on the way is a Rockford Fosgate P500-1bd. I am going to wire it down to 1ohm this time so I should get more out of my set-up this time. Then in a few months or so I will start replacing the factory speakers when I have the money. I am interesting in seeing how much of a change I get with the new set-up.

I am not exactly sure what is wrong with the old one. Simply put it is like there is no signal or power coming out of it. It powers up no problem but that is the only thing it does.

 

want to sell it broken?
