Bass Boost, Amp Vs HU?

I did frown on the redlines. Stamped steel baskets don't do it for me

Doesn't mean they're not adequate for the application.

Right, but I wouldn't use them for my application.

Who's frowning on the Redline? I haven't used them but I've heard nothing but good. And I saw a ridiculoud number done with them.
(Mispelling kept because it's hilarious. And poignant)

I dig that word. Here are a couple examples:

Once again I will say that I would not buy their redline series. Most of the big companies have entry level stuff. You're paying for the brand more than the product or R&D. Many people buy redlines so they can say they have DD.
Smallest DD sub I'd buy is a 3500 if I was going for a SQ system on low power. 9500's if I wanted a reasonably priced trunk build. Probably wouldn't buy the ceramic 9900's with 4" coils' date=' honestly. Z's for anything the 9500's can't do[/quote']

I don't think anything lower than 35XX for DD is worthwhile.

Not calling anyone out so I took out the names of the quote authors, opinions are another reason why I am here - real perspective from real people on stuff I am curious about. There are a lot more here, but it doesn't bother me as I just had no idea they were frowned upon as much as they are.

Redlines = loud, low RMS, budget friendly, well built, very reputable company, not RF/Kicker (lol, ex fanboy of both in their good years).

Some HU's have a subwoofer output level...such as my Alpine 9835...which I use.

My amp has a 18db bass boost...which is at "0" and always will be.

Correct me if I'm wrong but doesn't bass boost also lead to clipping?

Bass boost on amps is essentially a EQ that can only go up at a set freq or some have adjustable freq. just like any EQ a little bit of boost might be OK. But nobody does just a little.

let me guess. You arent getting sh*t for output with that vfl 4480.1d?

American Bass PH4000MD* and it's not even hooked up yet so I wouldn't know, said I was curious for a reason cause I didn't know. Not cause I need it.

Bass boost that is infinitely adjustable throughout a range using a remote knob is much more useful than a switch. In this case I would use the adjustments on the head unit to add bass to taste at low-medium volume.

I wouldn't bass boast the amp ever. I'm a noob, so some of these guys have better incite. But when i tested my Alpine M110 with a scope it would clip with any boast at about any volume from the amp. I have a 8 band EQ built in my HU, and I could go 1-2 DB at 40 and 80 Hz fine at louder volumes (35/40). I currently run -3DB on my 40 Hz, and -2DB at 80 Hz. It gives me a much cleaner smoother sound and it feels like it thumps better too. This allows me to go up to 38/40 cleanly.

I haven't scoped it with my HU set at -3/-2(40Hz/80Hz), only 0/0, 0/1, 0/2, 1/0, and so on to see what I could do with a boost. The doors never clipped, even at 40/40 which suprised me. IDK what I got with the sub yet. I haven't had a chance to pull the car into work to hook the scope up. I'll do that after I fix everything else wrong with my build //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Turned off my bass boost on my HU today after this discussion last night, lol. Now I can turn my in line amp knob all the way up. This KAC-9106D is actually a darn pretty decent amp it seems, can keep my '05 built KX-1200.1 in storage.
