just got new HU not paying attention to the 2v pre outs!!

[BoomTaco64]

the only way to get 2v out on that radio will be with it at max output. same with any radio on the market. the only way to get the max pre-out voltage is at max volume. getting the volume up louder on the radio will help out with your overall volume. the amp had no idea what radio you are using all it sees it a signal input and voltage applied with it.

okay that makes more sence to me i just wasnt sure if some amps are more "sensitive" then other amps if that makes any sence haha

i have tested over 100 aftermarket radios for clean non clipped outputs and almost everyone will produce an unclipped signal at 98% volume. Example...Kenwood kdc-x395 will produce a 4v output clean at full (35) volume as well as a unclipped signal on the speaker outputs as well. proper tuning of a stereo system is one of the most important things to do. do not use any mp3 files or compressed files as you will not get the best quality sources. i always use store bought cds to tune my systems because that is the cleanest file you can get into a car unless you have a vinyl player. (that would be awesome if you do. i want to see)..haha good luck with your tuning.

your 4ch amp gain is too high if you are distorting at 52. turn all gains down and use a higher volume for tuning. as well turn your sub volume up to almost max. when tuning do not have any eq settings on, no bass boost, no loud. set all to flat then tune gains. use a dmm and get the proper ac voltages you are needing then tune other settings by ear.

Components (door speakers) do not run on an amp they run thru the HU being that they are stock speakers. Also when tuning sub stage i leave all levels flat and place mids/highs to -6 also leaving sub stage crossover at 0 since if i need a little more power i use the crossover level on the HU to add power.

DEH-P4600MP

DEH-P4600MP - | Pioneer Electronics USA

The receiver does 22 Watt - 4 Ohm - 50 - 15000 Hz - THD 5% - 14.4V DC - 4 channel(s) but can max at 44watts 22 continuous.

That amount of rms is no where near distortion for what the stock speakers can handle.. I just think i need to upgrade from this old receiver.

I actually do own a vinyl player.. it hooks up via rca and aux, but its not expensive any dj store has them for 30$ or more mainly for mixing (chopped and screwed)

most pioneers i have tested go to 60 out of 62 without clipping

Need to turn up SLA on pio 2v HU's...will make a HUGE difference

Not all Pioneer Decks have SLA Feature.

Either way SLA feature is another GAIN setting which causes distortion if the amp is not configured correctly with SLA upped.

SLA is the only way he will ever see 2v out of his preouts, assuming his HU has it...

SLA needs to be set first then adjust gains accordingly

Don't necessarily 'need' to see 2v of output (though it would be ideal) - amp gain just needs to be set for the appropriate level the headunit is putting out.

Hi Skip, I've got a AudioControl Overdrive(line driver). I'll ship it to you for $65.

okay that makes more sence to me i just wasnt sure if some amps are more "sensitive" then other amps if that makes any sence haha

Gains and filters are all out of wack.. New Rcas ain't gonna help a bit with ur current issue. Nothing wrong with 2v Pres at all.. In ur case if u had 4-5-8v Pres you still would have the same issues. Might wanna get it set right before u start stinking..

eq will be the better choice if you have an amp running the mid range. If you do have an amp running the mid range then try turn that down to balance out the system and see what it sounds like.
