Need help wiring 2 alpine swr-10d2 to an autotek 4050.1

BRX2000.1 is a good one. What is your gain set at and how did you set it? By ear, multimeter?

 

[tymewilltell]

My gain is almost to the max I set it by ear but no distortion when turned to the max

 

[CSCStang]

Yeah that amp don't have enough juice. Time to upgrade.

 

[tymewilltell]

Also I was thinking the way you and jeff said to hook them up wouldn't that be wired to where the amp sees a 4ohm load instead of a 2ohm load?

 

[CSCStang]

Not with 2 subs.

 

[tymewilltell]

Ok got ya.. thanks man bout to go grab that brx 2000.1

 

[tymewilltell]

Ohhh ok I get it..the subs are wired at 4ohms but since the amp has 2 speaker outputs it makes it parallel and the amp sees a 2ohm load...wow what a crappy amp lol

Hey jeff thats exactly how I have them hooked up right now and thought I did something wrong does feel like its about 300 rms coming out the subs. Not hitting hard at all. Dang looks like I need another amp any recommendations

Well with D2 subs, your limiting yourself to a lot of power that could have been had, even if you get a brx 2000, your still going to be seeing only 600ish watts a sub. Also to note, if your running 2000 rms on a stock electrical charging system, expect a lot of voltage drops that lead to blown equipment. You'll need to do the big 3 upgrade and upgraded battery if you want to safely run a 2000 watt system. Also even if you dont hear distortion, you never EVER want to max the gain on any amp AT ALL. after a certain point usually 65-70% the amp starts clipping even if you dont hear it.

you have 5 options.

option 1(cheapest): get another exact amp and wire each sub parallel to each amp so each amp sees 1 ohm impedance and should give you close to 1k rms each sub.

option 2: sell the autotek and get an amp that does power at 2 ohms. Like kicker zx2500, alpine mrp 2000, rockford 1500 bdcp. Can get expensive

option 3: buy a good amp that does 2k rms At half ohm. sundown sax2000, soundqubed 2200, crescendo bc 2000, lanzar opti series, etc. This can get really expensive because you'll need crazy electrical upgrades, but you'll be future proof for better builds.

option 4: sell your subs and get D4 subs that only need 600 watts or so to get loud. higher power numbers do not necessarily mean louder subs, it just means they can handle more power. There's guys with 8 inch subs on 200 watts that do 140 dbs in spl competitions.

option 5: build a better subwoofer box. Make a 1/4 transmission wave (t-line) box and the subs will get crazy loud with very little power. Takes up a lot of space though. Or a very good ported box would be fine too. I'm guessing you have a pre-made chinese cookie cutter sub box?

I suggested the brx because those r's are 300-1000 rms rated and I've read that they have a hard time at 1000 and he can get one for around 200.00. The mrp is about double that.

 

[tymewilltell]

Wow ok jeff thanks for the info...looks like im gonna end up being broke lol I will definitely be doing some upgrading

 

[CSCStang]

Yeah it can get pricey haha. Gl

 

[tymewilltell]

Ok so I decided to take the cheapest route and ordered the exact same amp..got a deal by the way..hooked everything up the exact same way as the other amp wired the subs down to 1ohm and it sounds way way much better. The only concern I have is that one amp and sub gets really warm while the other stays cool..I have them both on the same settings

 

[CSCStang]

Which amp is getting warm, the new or used one? And you're saying the sub is getting warm too?

 

[csu87 10+ year member]

That amp is clipping

 

[tymewilltell]

Yes its the new one thats getting hot the sub is too..its not hot to touch but pretty close
