How To Connect A Subwoofer Rx400 Or Rx330

[NeoN]

ok well to sum things up... I ripped everything out last night..literally all of my trunk, i shall post pictures later

i did the 9v test with the speakers and located all front/rear/tweeters on the harnesses, found there are 2 tweeters up front on each side, but i need to test them again to make sure they are wired together. it said on the test that you can watch the speaker with the 9v battery and if it pops out that wire is positive and if it goes inward its negative. they are both like 1 ft from each other on my dashboard.

last night and i hooked up 3 wires (coming from the front speakers going into my Line Output Converter) not the 4th though, somehow its louder than with all 4 hooked up into the LOC. Dunno why but it is. maybe its not as clean or clear. with 4 wires hooked up it sounded the same as before, when i had the LOC running from both of the rear speakers, i figured that it might pull more bass up top from those since they aren't 6x9s. maybe its a a little louder than the 5" in the rear but not noticiable. I have a feeling that even if i were to get a clean sweep it might sound the same, its worth a try though i guess.

as far as ripping out the stock head unit and tapping the wires back there, but if its amped internally then it wouldn't matter where i tap the wires right?

I just realized that the speaker wires going from the head unit to the amp are extremely thin, you think that could be a reason there is no bass? even though the output wires for the speakers are thick would it matter at all? if I tapped into the head unit, the wires are still going to be razor thin going from the head unit to the amp, which isn't good. there isn't really anywhere we can tap into then if the wires are tiny leaving the head unit itself, its not like its aftermarket with a pre-out for subs already made.

the best thing might be to run a clean sweep and try and raise the gain on the subwoofer itself

i might try and tap into the wires leading into the amp even though they are really tiny it can't hurt. maybe that amp filters out some bass?! ill find out tonight.

i might just use my own amp for the door speakers and bypass the factory garbage, well see.

my soundsystem is working perfect now, i might mess around some more but its good for me for now, its funny how easy it was to rip apart the interior though, im not sure about a clean sweep everything seems fine

ps. incase anyone didn't see,

if you want the best sound for your sub, tap into the factory amp.

wires are

front driver: +pink/-black

front passenger: +purple / -white

you dont have to take out the seats,

side upholstery, you could easily do without taking out, but you would have to wiggle out the carpet piece held down by it.

you dont have to drop the engine,

but i didn take out that metal piece ontop of the amp to get better access to it. made things much easier, I took apart everything mainly because i didn't know what i was doing. Hope my documentation helps, pm me for questions,

im still not done though, tongiht im going to try and tap into the smaller harness coming from the head unit to the factory amp.

I went back in and hooked up the sub to the wires running directly from the head unit to the ---> amp, basically a line out level. It's unfiltered sound, nice and clear, but the issue is the bass is the same regardlress of volume level, so i can crank up the volume and the bass stays the same, not exactly what i had hoped for, but its clear and i can adjust with my bass knob I installed up front. The problem is the bass is too loud with the knob turned all the way down, which isn't idea when you have passengers. I might go back and re-tap the speaker outs from the amp. I'll give this setup a week or so, to see if i can tolerate the sub boom levels from the line-out..

ps, i bypassed my hi-low converter as well, running straight RCAs from my amp to the speaker inputs from the head unit ---> amp...

pics to come, and a conclusion
