Hooking Up Amp To Factory Hu

[silver2003]

I did a search on this topic and found some good information. Some people said if you use the high level inputs to hook an amp up it doesnt sound very good. My question is if I hook up my cross over via the high level input and then run rca from it to my amp would the sound quality improve? Has anyone done this?

you have a couple options.......heres what you could do first run them to a line level coonverter that changes it from high to low level and then run that into a crossover that has a signal voltage upgrader, that boosts it to to 6 volts or something, that way you have access to all ur frequencys, if you get a nice crossover youll have tons of out puts, and ur sound will be fine..........

you can do it your way but ive never seen a crossover with high level inputs, make sure the voltage outputs are decent, somewhere between 4-7 volts........any other questions just ask

buy an amp with a highlevel input and it sounds just fine.

I have a punch 360 to run my subs and another for the mids and highs. both have hli on them i just figured it would be easier to run rca's from cross over to both amps. my cross over has both rca and H L I on it. Easier than running all H L I wiring to amps

The degregation in sound from high level inputs is solely dependant on the Head Unit. A decent head unit with a clean internal amp can be ran through a high level input with as much distortion as a cheaper head unit using low level. However, what you have to remember is that high level is already amping the Head units signal. As volume goes up so does distortion. When taking that amped signal and running it through a LOC you will only boost what distortion is already there. Boosting the signal to four or six volts will not get a cleaner sound but just make it easier for the amp to operate. If a sub is the only thing being ran, then sound quality would not be a concern. If your mids and highs are going to be used, then concider going with the pre out if available.

yea a more efficiently running amp is going to give you better sound quality, I have heard plenty of amps when they start warming up and I can hear the difference........why do you think the upper brands and upper models come with a greater voltage output on the pre outs??........i had a pioneer with a 2volt and now i have a pioneer with a 4 volt and i can hear the difference......a friend has one with a 5volt and it sounds so clean......I do agree that a bad signal to start with will not go away with amplification........and like you said theres a reason certain brands are expensive......
