Replacement for Alpine PXA-H800

[andeee]

Hi all,

Seems like my H800 may be dying or at least it's not working properly anymore. I think the RCA ports for the tweeters is killing rca cables or something as one of them works and the other doesn't sometimes. Don't think it's the amplifier because I just replaced it. What would be suitable replacement for it? How are the Helix processors? The DSP .3 looks like a close match price wise, maybe worth stretching the budget to the Pro?

I had issues with my H800 as well....RCA issues and it seems the processing fails sometimes...can't really put my finger on exactly what's going on with it.

I'm replacing it with a Dayton DSP-408....it's a basic DSP but covers all of the bases except a center channel, which I won't be using anyway.

The h800’s have had some internal grounding issues if your handy with a soldering iron you can pop the case and go on the inside and touch up the grounds and it usually fixes the intermittent output issues .

Do you have any specific info on this? I wouldn't mind trying to fix mine. Thanks!

Hmm, I'll give it a look. I bought it about 8yrs ago now, I guess when they were first around? Have They always had this problem? This only recently started happening.

Anyone with soldering experience should be able someone that does basic electronics repairs could handle this . Mainly your just touching up a few cold solder joints around the rca outputs on the brain case . If there is a CB shop at a truck stop in the area they can do this type of work for cheap . It’s not really a bad part repair it’s just helping the connections get better contact .. it’s definitely worth trying before spending a lot of money.

Thanks...I'll give it a shot this weekend. The RCA connections themselves on the H800 didn't impress me too much...half of them pulled right out of the unit when I removed RCAs.

I’ve had amps do that .. if able upgrade the RCA’s to chassis mount style a far better connection . I don’t know how to add a link by phone but I photo shot what I’m talking about you can find these on search on eBay ..these are fairly cheap good reviews and would make a nice upgrade over the cheap Alpine factory RCA sockets
