View Full Version : Running speakers just off HU.

12-04-2008, 12:36 PM
So I recently just took out my system do to space issues. My head unit only puts out 16x4. I'm just looking for loud vocals, no bass needed (obviously since I just took out my BTL :P), trying to run a set of comps or coax off it. Prolly slim chance I know. I have a Sundown 100.2 and no, I don't want to use it. Just don't feel like running them off an amp. Don't feel like running power wire, mounting amp etc, wiring speakers, etc. Just don't feel like it. Any help is greatly appreciated.

Depends on what speaks you get. you can get some that would actually be fine off HU power. Its just kinda weak and usually the speakers dont sound as good.

When I was stuck running the stock radio in my car I upgraded the awful stock speakers with Infinity Reference. While by no means great speakers, they were cheap, efficient enough to be decently loud on stock HU power, and an immense upgrade over the stockers.

Go back to OEM mids the car came with then, I will buy the 100.2 for $100 if you dont need it = )

I actually ran a kicker component set of a head unit when I got my very first system and believe it or not it sounded really good. As long as it a lower power handleing set you'll be fine.

still looking for some possible ideas

I rock JL coaxials. I think it is the TX series. However, I am thinking of finding a full range 4" for the fronts.

you run them off your headunit?

12-05-2008, 09:00 PM
Yes. A old pioneer. I am tired of car audio at the moment. It is okay at best.

12-05-2008, 09:20 PM
how much power are they getting?

Alpine type S does okay off HU power. I say you get your lazy *** out there and install that amp.

Wait.. The type s set I heard was ran active off a 9835 hu.. Each speaker had a dedicated channel of POWA off the HU.

I just drop one my alpine type s coaxial the other day and the tweeter broke. I wasn't sad at all. they sound like ****

I'll try some polk db. Nice speaker at a great price. I used to run some 6x9 for over two year and they were loud off little power

Does anyone make small amps, that you could fit in your door?

12-07-2008, 02:11 AM
You want to look for high sensitivity ratings to get the most out of headunit power. For example if pioneer speakers had a sensitivity rating of 87 db and infinity had a sensitivity rating of 90 db. That would be 3db more meaning that is a doubling of your power from your headunit.

In other words the infinity's would play twice as loud as the pioneer on the same power. Sensitivity is everything if your looking to get the most out of your headunit. The boston acoustics s series full range speakers is the best you can do if your looking to get the most out of your headunit. There speakers have a sensitivity rating of 92 db.

I ran polk momo's off my alpine head unit for about 4 months and it sounded rely good. The bass hit slightly hard shook my mirrors lol and was able to crank it pretty loud before distortion. Go for it they will sound pretty good.

Anyone else with sugguestions?

12-08-2008, 01:49 AM
um, I second putting the amp in... it'd be just as easy as wiring up the sub amp. obviously you had an amp to run the BTL unless you ran that on HU power as well.. a good reason to buy the cheapest wires you can get. you can leave them there even when you sell the car LOL...

I actually left a pioneer 8400mp and Orion P6.2 components in my last car I traded in... car was fully dynamated too, they kinda scored on the audio front...

yeah I ran the btl off headunit power
