mb onx4.80 clipping too low

[john253a]

just finished a budget install

i mean real tight budget install,

ive used the older mb stuff (10/11 range) but not the new onx ones to drive subs

used the onx4.80 twice before but only on speakers

the install is 1 set 7x10 kenwood on rear deck and a kicker comp15 in a kicker ported box svc 4ohm

all set with dd1,

and as normal -5 for the mid and -10 for the sub

mid work and sound powerful and loud on there 80rms each

much louder then the comp15 on 320rms @4ohm, bridged

i found the clipping on the dd1 to start before i even got 1/4 gain on -10

where as -5 on mids was close to half

h/u clips at 40hz -0db at 46/52 and mids 43/52 (4v pre out)

so im using 42/52

just wondering if anyone else has experienced this with the same amp bridged

ive tried switching sub from 3/4ch to 1/2 ch and same thing there,

even if i test the mids with the 40hz track (witch ive never done before) the gain need to go down

First off, I'd suggest 0db for mids and -5db for subs.

Second, using a multi-channel amp bridged for a sub sucks balls. Speaking from experience.

Using the -10db track for subs, I guarantee you are clipped to hell on most modern hip-hop/rap tracks.

Where your gain is pointing doemst matter

40 hz and 1000hz are different to obviously youll se gains on different positions

Have you tried doing all 4 channels with the same tone and see if they come close?

Also the do you have bass volume control on your headunit?

But I don't see really see anything wrong

Just be carfull with your bass(since you use the -10db) just cquse you tuned witha dd-1 doesnt mean you'll be able to max on every song

i use the -10 and -5 mid with all my installs

ive also used this sub before on a zx350.4 (175rms bridged) and its twice as loud in the same car

70% of installs done down here are sub/front or sub/rear on same amp, or a 5ch is use, unless there big bass heads, witch theres not many due to the price

not to manny want to drop the coin for 2 or 3 amps when we dont get budget/entry level equipment, or even the prices you do

the mb ony4.80 is a $590au $600-610us amp in aust, so you get a comparison of what we pay for stuff

i agree with the multi ch. i dont like either, nore do i run mine like that

on -0 for mids the h/u is louder on its 18rms of out put

i test the leads with a y-adaptor and thats where i get the volume of 42 out of 52, set at with flat eq

then i check it through the amp on all 4ch and i clip at 43 with no gain, and at 42 i turn like nothing and it clip

i havent checked the high level output on the h/u

the main resion im asking is because i dont believe the quality is there on that brand of amp, and i want to see if anyone else as noticed it or did i just get a bad one.

if it was where it should be volume wise for that setup there would be no issues,

and i understand that the position of the gain nob means little to nothing

im getting the car back on the weekend, so ill clamp it on the -10 where i set it at see if im getting the anything close to the quoted 320rms @4ohm

witch it should be,

even my shitty kicker ex15 (in kicker box) on 150rms (kx300.4) is louder then this (work car so what i had lying around)
