Chris Posted May 4, 2007 Report Share Posted May 4, 2007 (edited) I have a problem. Today I spent around 3hours putting in my friends system into his 06' grand prix. It consists of 2 12" L5's & an MTX 502 2-channel amp. I ran all the wires just they way I've done countless times over the years & everything turned on just the way it should. His car has a factory integrated amp system so I had to use a line-output converter attached to the rear 6x9's for a signal. We turned everything on & the subs move about 1 inch each & seem to be getting the power they should. The problem is that the factory 6x9's are louder than the subs!!! The subs look like they are moving nice but are VERY quiet! Any suggestions would be so appreciated as I'm getting paid to do this job!

Chris Posted May 4, 2007 Author Report Share Posted May 4, 2007 I forgot to add that I tried connecting 2 different line-output converters & they do the same thing. The subs look like they would be bangin, but aren't loud at ALL. I've adjusted gains & frequencies & settings & I'm almost thinking it's the car's acoustics. We even tried turning the subs forwards & backwards but no luck. What could be the issue!?

Ray Posted May 4, 2007 Report Share Posted May 4, 2007 the factory amp is high passing the 6x9's. You are not getting any bass freq. You need to mag the tag low level before the amp.

Chris Posted May 4, 2007 Author Report Share Posted May 4, 2007 the factory amp is high passing the 6x9's.You are not getting any bass freq. You need to mag the tag low level before the amp. But the 6x9's have huge bass compared to the subs & thats where I'm getting the input signal from. What do you mean "Mag the Tag?"

Chris Posted May 4, 2007 Author Report Share Posted May 4, 2007 I'm still kind of confused actually. Are you saying I need to splice into the factory radio's speaker outputs before they enter the integrated amp?

Saltine Posted May 4, 2007 Report Share Posted May 4, 2007 i had a problem similar in a 91 bronco 2. the highs overpowered the sub. turns out you had to turn the bass all the way up on the H.U. for it to really slam but it put all the bass into the highs also. so without some bass blocker things it was pointless...zero bass on the H.u. barely moved the sub other than that i dunno Quote Link to comment Share on other sites More sharing options...
Chris Posted May 4, 2007 Author Report Share Posted May 4, 2007 For me it's wierd cuz the subs move A LOT, but they just don't have that power I'm used to.
