I dunno about all those HO alternators.
I've only had one, and it burned out within a year.
My car bumped a lot harder by adding 2 more 12's to the existing 2 than it did with any amps over 1000 watts, even after the alt.
And my lights still dimmed with the gain up.
In my case it was just a waste of 300 bucks.
Maybe mine just wasn't built well.

...90 amps should be plenty unless you're planning
on winning some high end competitions.
That's more than my escort has, and it shakes the ground(4 15's on 1 amp.).
Might as well use yours as long as it's good if it's not starting to fade.

If you want your ride to bump harder, get more subs and amps. Even entry level stuff does great when there's lots of it.It's cheaper and easier to put in 4 p1'sor whatever off ebay than do up an alternator.

Or maybe I just need to put the blunt down. Peace.

4 15's fit just dandy in an escort wagon. I had to take 2 of them out of the ported box and build one so I could stack them,
so 2 were vented boxes and 2 were sealed, but they fit just fine. A lot better than in my taco, that's for sure.
Dumped too. I was gonna put 10's in also cept I'd of had to make it a 2 seater wagon.

I don't take pics of my sh*t, cuz if I want to show off, I just turn up the gain.
My scort also doesn't have the subs because I moved 2 of them to my yota.

And I got the alternator from some guy named scott
chang who ran a now defunct website I saw advertised on an auction on ebay. Not really anything I could do but learn to avoid a mess like that again. Just don't buy sh*t from anyone with 'azn' and 'tiger' in their account names.

"the lights dimmed with the gain up"

Bro the gain is not a volume knob, is to match it with the HU preout voltage so... BS for ya

Julio,
what does that mean? Why am I gonna lie about my lights dimming when the bass hits?
Doesn't that seem kinda pointless?

the gain isn't a volume knob for the amp....so when you wanna show off, you sre simply clipping thehell out of your subs...smart move:-)

i don't see the point of 2 ported boxes, and 2 sealed boxes...why bother having the sealed boxes??????

the ported would be louder at every freq., thus drowning the bass from them out, unless you went below tuning...then it might, MIGHT level out.

also, the gain is used to match the Pre-out Voltage on your amp to the HU.

Muddy, that's just for us - dummies. Guys like Jerome long ago started using the remote gain controls in their set ups:-), the so called "second volume control":-)

...Then why do they even make a remote gain control?
Or maybe I'm using the term improperly.
The remote bass control, the little knob with the phone jack things that most newer amps have.
That's what I'm referring to by gain.

And I only put 2 of the subs in a sealed box because 2 vented ones together are too tall for the truck.

...Somehow, I sense that I am being mocked.
Yet I'm too ignorant or too new school to understand it. Oh well. Later.

listen. you shouldn't use the remote bass gain, b/c the Gain is supposed to be set to the HU's preout voltage and left like that. not making it more sensitive(lowering it) or less sensitive(raising it) to suit you output needs. that is what the Sub-level out on the HU is for.

the gain is used SIMPLY to make sure the amp gets the correc voltage in to amplify out. if the gain is set to sensitive, it will clip the signal, hence comes the statement "it should be set and left alone, increase the bass in your Hu's EQ if you want more, don't fiddle with the amps signal input setting. thats all.:-)

also, 2 sealed boxes and 2 ported boxes is pointless, b/c like i said, ported are louder at every freq. above tuning. so they will be louder than the Sealed boxes all day. making the sealed boxes useless, b/c you cant hear them evenly the sound from them will be "under" that of the ported boxes.

haha, you are being mocked. 2 sealed subs and 2 ported subs in the same ride! bet that sounded like shi_t! and a remote bass know is not the same as a remote gain and you do know when you use a remote bb you have to reset the bb on the amp itself.

yes, depending on what it is. you will have to do diff. things.


if it is a remote bass gain.then you will need to set the gain on the AMP to your HU's preout Voltage, then you can run the Remote all the way up, and not harm anything b/c it will only go up as far as the AMP is set.

if it is RMB(remote bass control) then it is a Bass Boost knob. which increases the BB on your amp. and oyu will have to set it to wide open to get wide open on the remote as well. Bass Boosts are centered around 45hz...so you will get more of a boomy sound than a flat across the board increase in output.

I see. Yes, it is a rmb that I was referring to as 'gain'. I took the time when I put the amp in to tune it properly, really the rmb is because some music just doen't hit like others or I just wantto be loud.

And 4 subs will dump harder than 2 regardless of the box. Even 0pen air, probably.
When I put the sealed box on top of the ported, it hit alot harder. Although it did lose some sound quality; The bass just thundered, but I lost all the high bass notes.

Hence my making a thread about putting a 2 channel amp and some 10's in there, to pick up the frequencies I'm missing.

And I do use the HU sub control as well.
But you can be a lot more accurate with this particular amp's rmb. Not like I'm reaching to the amp and cranking the gain literally, although I guess that's pretty much what I wrote.

Anyhoo, thanks for schooling me on my lingo, maris especially.
