jessdabest77 Posted April 26, 2014 Report Posted April 26, 2014 I was wondering if running a pre amp to a good 4 volt stereo would make any difference?I'm thinking of getting a Kenwood Exalon or Pioneer 4 volt deck,but thinking if also putting a pre amp would get the high's and bass louder?Any thought's?
Nightshade Posted April 26, 2014 Report Posted April 26, 2014 If you are already running a 4 volt deck you probably don't need a preamp. One benefit of a preamp is that you can turn the gain down on the amp and get the same amount of output that a lower preout deck would provide. The benefit of this is sound quality, with a lower gain there is usually less distortion produced and can help the overall sound. There isn't much other reason for a preamp with a deck that puts out 4 volts. 2013 VW Jetta GLI 2.0 Turbo 1 Sundown Audio SCV2000 1 Sundown Audio X15 V2 1 XS Power D3100 Audio Control LC6i Stock Deck 146.4 sealed on the dash at 37hz 2001 Focus ZX3: RETIRED Team Sundown Audio, Team XS Power, 2 time NSPL Car 3601-Up Champion, 2 time NSPL Car Hardcore ChampionHighest NSPL Scores to date:154.3db on the dash sealed at 46hz, 156.2db in the kick at 46hz155.2db unofficial on dash at 43hz
jessdabest77 Posted April 26, 2014 Author Report Posted April 26, 2014 Ok,good to know,I just thought a preamp would be louder and clearer sound than a stereo,cause I've seen big system's use it.
Nightshade Posted April 26, 2014 Report Posted April 26, 2014 The reason very large systems use them is because they are running multiple amps. Once you start to run more than 4 amps off a single rca output there is not enough preamp voltage to go to each amp. In this case a line driver or preamp is added to boost the preamp signal up to 10+ volts so each amp has sufficient signal voltage. 2013 VW Jetta GLI 2.0 Turbo 1 Sundown Audio SCV2000 1 Sundown Audio X15 V2 1 XS Power D3100 Audio Control LC6i Stock Deck 146.4 sealed on the dash at 37hz 2001 Focus ZX3: RETIRED Team Sundown Audio, Team XS Power, 2 time NSPL Car 3601-Up Champion, 2 time NSPL Car Hardcore ChampionHighest NSPL Scores to date:154.3db on the dash sealed at 46hz, 156.2db in the kick at 46hz155.2db unofficial on dash at 43hz
