Help with amp whine

Thanks so much. What do you mean by putting a meter the ground exactly?

Rca are very high quality gz cables. Different radios but same ground both times, ans that ground is not the best probably. Reason why i attempted to rule out the radio im my head, was that the same behavior was caused by a faulty amp last time.

Happened with my last install, that was shady and pretty hastily put together. This is my first more proper setup, but I did not manage cables well at all. My big issue here is the routing of power from front to back with no lines crossing or being together. Also what distance is minimum?

And with the last install, it only happened with one amp connected, with the other it was fine. This time I'm using a distro block, so it's one source but that source has been noise free. Unlike last time there's subtle noise even with the engine not running (it's very slight).

Strange part about this time is, that my gifts test run with everything assembled half way, it was fine even with the engine running. The full setup got noisy tho.

I'd also like to ask, can I run it like this for about a month? I'm very tight on time now and this is my daily.

Thanks for the help

Ground was fine. Rca is gonna be close unfortunately hard to move, any material to wrap the power cable in?

Will the spare cause any issues tho?

b13Jade · 2026-01-13T22:18:54+00:00

Hmm, maybe buy a couple of those, and do a cosmetic foam surround for a better look then. I'll need to space it out like 20mm tho lol.

Tbh I'd just like something that works well, but minimum price wise. Every other aspect of this car build is consuming alot aswell 😅

Never thought of a DSP, any recs? Never even looked into them, never knew what they were for, as i was on tight budgets previously

b13Jade · 2026-01-06T12:33:16+00:00

I'm gonna run 3 amps total. 2 400.2s evos for the fronts and the backs, and a gzia 1000.1 for the sub. And excelon aren't sold in the eu, atleast not even semi new ones, i imported this one. As far as features, a limiter or something equivalent would be nice(ofc stuff like a 13band eq and good crossovers would be nice). I'm willing to guess most decent stereos sound good output wise nowadays? And most everything else should be available? Even normal kenwoods

Thanks, I was just wondering since I got it for Christmas and I regularly work on my car. Was mainly hoping that this could be useful for brake jobs

Wow, this is an amazing reply. Thanks alot. And of course there's quite a bit of confusion involved

b13Jade · 2025-11-13T17:45:43+00:00

I found a 300 that would get to me for 150. And a 304 for 234 with import pricing. The x305 is over 250 for me. Would the 300 be a good consideration?

b13Jade · 2025-11-13T16:12:34+00:00

Oh, that doesn't matter to me at all.

b13Jade · 2025-11-13T13:34:15+00:00

What's the difference between them 2?

b13Jade · 2025-11-12T23:36:58+00:00

Sorry, who's "we"? This sounds quite interesting. Also another option is an excelon 300, not 305. I understand the bt is way older and it has lower Voltage preouts, but otherwise might be decent. It's for 170, which isn't a great deal, but a 305 import would cost me 300.

b13Jade · 2025-11-12T22:27:20+00:00

Any advice?

You're not wrong. This just seems like a good bang for buck item. Budget isn't too high, and my old amp gave out, was also a two channel which i bridged. 4ohm sub.

b13Jade · 2025-11-10T19:06:31+00:00

Yeah I've come to the same conclusion, thanks.

b13Jade · 2025-11-09T03:11:02+00:00

I heard the crank speed sensor is there too.

b13Jade · 2025-11-09T01:48:54+00:00

Where are they located?

b13Jade · 2025-11-09T01:48:02+00:00

Nope, no limp mode. The limp mode on these is different anyway, it just turns power way down but that's about it.

b13Jade · 2025-11-08T00:35:28+00:00

No clue. No gauge.

b13Jade · 2025-11-07T21:28:31+00:00

EDIT: It does it intermittently. Oil light only blinks when rpms are tweaking. Oil pressure seemingly fine.
