Alpine PXE-H650

[ticklenow1]

Has anybody had any experience with these processors. Or any others for that matter (Rockford 3Sixty.2 or JL Cleansweep).

From what I can gather from looking on other websites all of them have pros and cons.

I am trying to improve the sound in my car without replacing the head unit. I have Hertz Hi Energy HSK165 splits in the front and Hertz Hi Energy Coaxials in the rear. The front doors are dynomatted and all wiring is done to a high standard. Amp is an Alpine PDX 4.100.

I find the sound a little flat coming from the rear and there is little or no adjustments from the Euro head unit.

My local audio place tells me that one of the after market processors will fix most of this problem (but not all).

I am tossing up between the Alpine or the Rockford. Both seem good on paper and both have features that the other one doesn't.

Any reviews on these products would be really appreciated.

how many forum's you going to post the same question on?

H650 works well, but the setup sux and its not worth the money as you cant do any tuning after you run imprint. get the 360.2, lots of control...

i have the JL Cleansweep, i looked at the RF 360 as well, but imo it looked too complicated for me with the laptop blahblhablah so i stuck with the cleansweep. im running the cleansweep off the rear speakers to provide a signal for the amp to run my sub (stock sound system all round atm), and from what i found its pretty shit for my setup. everytime i increase the bass from the head unit to hear the sub, the front and rear speakers just go DOSHDOSHDOSH and i try to turn up the treble to fix this, but the treble just plays through the sub and wrecks the bass from it. apart from that, if you were planning to change your rear and front speakers and run the cleansweep off the head unit to provide a signal for the amp, i rkn it does a pretty good job and bang for your buck. thats my 2 cents.

Perhaps you should investigate making a 12db / oct HP for your speakers so they are not playing a full spectrum of music when they don't have to...

For a 4ohm speaker, to HP them at about 80Hz 12db/oct you will need a 11mH Coil and a 330uF Cap. Cap gets wired into positive side and coil gets wired across the positive and negative.

After much deliberation, I think I might go for the Audison Bit One. It is a bit dearer than the Alpine and about the same price as a 3sixty.2. The Cleansweep is not a consideration as it has no EQ adjustments. From what I can gather all it does is give you a flat EQ. The Alpine is very limited in it's EQ adjustments and the Rockford is tuned with a Palm, which only adds to the cost. The Audison looks like it has taken most of the good bits from the Alpine and the Rockford and put them together in one package. It does not have some of the fancy Alpine processing, but after talking and listening to a few people it does everything better than the rest.

Thanks all for your help.
