Yep.

OK, made measurements today. The SPL Meter was wedged between the driver seat and headrest, the primary listening position. I took measurements for just the subwoofer and then fullrange. It is important to keep in mind that for both measurements, the EQ (Bass and Treble) built into the factory headunit were basically bypassed since the Line Out from the computer was connected into the Cleansweep. Any EQing was done from the Cleansweep... come to think of it, I probably should have made a few measurements with Cleansweep EQ Bypassed. But then again, maybe the Cleansweep EQ is automatically Bypassed when the Auxilary input is being used. Here are the results:

SUB:


Full Range:


The SUB in car response was not too bad, especially since there are no treatments (such as dynamat) or Sub EQing of any kind on it. There are a couple of +9dB peaks at about 30 and 47 Hz but everything else is pretty tame.

Full range response is a little more out of control. Mid-range drops off a bit from the bass and treble; if you consider the response at a target of 80dB, then midrange (400Hz-3500Hz) is down about 10dB. Upper treble drops off after about 10kHz but the SPL meter is not nearly as accurate in that range either. If the stock headunit EQ was not bypassed, then it would have been pretty simple to bring down the bass-midbass and higher midrange-treble ranges down about 10dB to flatten the response a bit. During normal listening, however, I can use the stock EQ.

ok....thanks i already got it done and it works great, can't wait to get the amps and the type-r

what sort of battery terminal did you use for the amp's power wire that allowed you to keep the OEM terminal?

quick question about the jd audio cleansweep. can you notice that big of a difference when you select the defeat button between eq'd and non eq'd? i have the exact same set up as you with different amps and am not happy with the sound. the midrange is seriously lacking with the current loc i am using. please let me know your thoughts on purchasing the cleansweep. thanks

I'm pretty sure that I just used a large crimp ring terminal for the amp power wire and ran the screw from the original battery connector through it and tightened it down.

I havn't tried selected between the EQ'd and non-EQ'd. I just ran the wizard and was done with it lol. I did do a slight tweak from the stock headunit to at just a little more treble. I can try it when I get home though. In the mean time, something you might try is to just turn down the bass and treble a little on your headunit which will raise the midrange relative to the other frequencies. Hopefully that'll help out.

Just a quick question....is the AOEM-HON20 connector a LOC? It takes the signal from the stock 20 pin connector and runs 4 RCA outs to the amp. I'm assuming it is the LOC. I'm confused and thought maybe you might know if it could be used in place of the Cleansweep. Thanks

ok i dont know if im just being retarded or what but from what i understand you need a remote cable for the amp to work if you/i have a stock nav radio unit where would the remote go to from the amp?

You get your amps remote turn on from a Line Out Converter (LOC). The LOC will send the 12V signal to the remote turn on for the amps when it senses an audio signal from the stereo, in most cases this is from the rear speaker wires.

so then the USA-Spec PA15-HON2 will work like that then right? as in the remote will come out of there? im kinda lost with all this. i just want my beat and my ipod with my nav still working

The USASpec does not have or require a remote-turn on lead. The USASpec gets power from the 14-pin XM/Aux connector. Just plug the USASpec into the 14-pin connector following the directions and it will work.

A year late, but kudos on a very clean job. Am assuming th sound Q is comparable to that of a decent after market head unit? Don't know what kind of signal processing is in the stock units.

A question was asked a few pages ago and I did not see a response to it.

I believe I read somewhere that the speaker wire to the tweeter is connected directly to the back of the stock HU. If that is the case, is the stock woofer in the front door only receiving a freq response that does not include the higher frequencies ( possibly indicating there is a crossover built into the HU)?

I am about to FINALLY replace my front component speakers in my 03 EX-V6 Accord. This was a great post!

But I am really interested to know if the speaker outputs from the stock HU is carrying the complete frequency response to both front and rear, left and right, and not simply supplying only the lower frequencies to the front woofers.

NOW this is for the non-Premium audio system in the Accords.

The speaker wire outputs to the front woofer/tweeter are full-frequencies directly off the head unit. There is no crossover manipulation other than on the factory tweeter itself. The wire splits two ways to the woofer/tweeter somewhere under the dash.

Sounds good, I have the non premium (automatic) stereo in my 2003 EX V6.

How about a remote turn on for the amps?

And I just ordered these Alpine SPR-17S components for the front:

Any suggestions on installing the tweeters for that "perfect" fit?
