finally its done, back seat amplifier

here it is boys and girls. i'm happy with it, might do something about the cut edge of the carpet around the plexiglas, thinking might sew some vynle which i used inside the box and have it wrap around to the back. so I will have the material actually cover a little more of the plexiglass as i had to pull it tight and use some 2 sided tape. and I will put velcro on the back as well

hope you enjoy, cheers

Looks great! I wish I could do the same with my amplifier, it's about the same size, but I have a 4-piece back seat. I'm thinking of redesigning the sub box and "flying" the amp over the woofers. Maybe sometime after tax return.

I actually converted over to a solid rear so that I could mount my amps back there. I wouldn't have problems fitting them in a split rear (they're fairly small), but I also wanted room to mount my crossovers, distro blocks, etc

mines bigger

i'd like to do that, but i've got split seats, and i dont think either one of my amps would fit in one, MAYBE the diamond. i think im gonna have to build an amp rack and some more weight in the back

I would convert to a solid backrest, but I had the split one re-upholstered not long ago, which means I'd have to do the same to a replacement solid piece. Too much $$$.

that 0AWG wire looks awfully small!

so where do you plan on putting all your other amps?

its not o gauge its actually 4 gauge into the dist blocks, then 8 gauge (2) for each pos and negative into the amplifier.

other amplifier (4 channel one) I'm going to put in the back cubby hole area. just hidden away

what kind of power are these amps? 8AWG is actually a little small for some amps... 4AWG is pushin' it sometimes... but as long as it's not too long 4AWG it's alright...

viper d.2500.1

something like 2000 rms @ 2 ohms bridged

it has dual connections for Positive and negative

so two 8 gauge in, 2 8 gauge ground


I see the connections are bigger, can accpept 4 gauge,

so you are powering, what, (5) 18" Brahmas?

and you would for sure need 0AWG or bigger...

your amplifier draws over 160 amps... so I guess you probably have two yellowtops along with at least one powermaster alt, or some custom high amp alternator?

sounds like quite the example of extreme overkill...

what kind of 10's need 700WRMS a piece?

better to over power than under power. and its 2500 watts @ full throttle on the amplifer, gain will be turned down as well as no bass enhancment. subs are oly mtx blue thunder right, dont drive car, but worst case scenario when or if they blow, they will be replaced with 3 10" alpine type R's


they subs are parrellel , each is 4 ohsm, so it will actually e a 1.3333 load, so even more power.


and also I will be upgrading my alternator, so no worries there

fellow owner said he had 12" of 8 gauge from dist. block to amplifier and I have less that that, said it was fine. just less power(as he's into spl) I dont need that full power output.

I'm just a little familiar with stereo stuff

Well I'm sure the previous owner had good intentions... but do you seriously think that an 8AWG wire has any place on an amp that you have wired to (theoretically) push 2500WRMS (I don't think it would make it that high though.)

No offense but have you ever looked at one of these charts?
Wire Guage versus Amperage Transmission

without looking at the chart, in my own head, I would have said never use 8AWG (and I know you're using TWO,) on any amp with more than 300 watts...

heck, if you go to the store, you'll see the different wiring kits that show the wattage their intended for... the 8AWG kit goes up to like 400 max or something..

hopefully you'll upgrade your wiring before you ever turn the gain on your amp above 10%.

I mean this amp is a wicked beast... I'd probably run double nought from the 300AMP alternator to the main battery, and double nought to the back of the car where I have a solenoid controlling a secondary battery... then I'd run quadruple nought to the distro then double 2AWG to that 2500D... I bet you can squeeze them in...

I'm only dealing with ~1400WRMS and I'm running/was running 1AWG wire to the distro, as well as the 1AWG to the amp.... I'm only looking at about 150amps total... so I don't need quite as much...

but just in case, when I wire up my new car, I'm going to put 0 or 00 just for future flexibility.

fellow owner had 12" of 8 gauge wire from dist. block to amplifier, I have half of that


he has however 0 gauge from battery to dist block, yellow top optima and said he had a 105 amp alternator at one time. upgraded to some crazy one as he is totally into spl has two 18" RE in there. hes actually a member of this board. i'm moving onto bigger and better things. this can be delt with later, as I dont even drive the freakin car(no motor, no trany, no susp. doesnt' have a deck, so I couldn even listen to it, and doesn't have a battery. even when done, I wouldnt not be worried about the amplifier as minimal to no gain will be used. but eventaully dont worry I will upgrade

battery is goign to be in trunk. run 0 gauge from battery to amplifier, then dual 4 gauge from dist. blocks into amplifier

sounds a lot better

if you have access to the amp... what fuses does it have?

hey thanks man, very much appriciated, trying to do my best and most thourough job on it. tryign to do everything myself, only way to learn


wont be painting, did that to my malibu. had enough of that, lol , I will paint engine bow however


I dont believe there were any fuses actually in the amplifier from what I saw, I didn't actually go over the amplifier too thourgoly , I had to ask previous owner how to take inputs for cables off, also found cross over etc is hidden under the viper snake head emblelm

I'm 99% sure that JL doesn't have fuses on their amps and I'm pretty sure that there are others out there too. There was a guy on here a while ago who said that he soldered his memphis fuse holders together with some heavy gauge wire at the direction of his dealer.

None taken. Everyone is entitled to their own opinions after all. Some people will still swear by sony/lightening audio Personally, I don't know enough about memphis to comment one way or another.

My point was that a few reputable (like it or not memphis is considered reputable) companies sell/reccomend running amps without fuses.

All I know is that the 1605D I had was not 'defective' by Memphis' standards... but no matter how I hooked it up in my car, I would hear a light 'rumble,' that did not increase with volume (meaning, it wasn't an input problem.) even did it with no source connected.

Sent it back, got a new one, (even checked the serial number.) Same exact problem.

Redid all my wiring again (even though I knew it was good to start with since I have had several other amplifiers.) No difference..

bought the nINE.1, and now my subs hit harder, no static, and it looks much better in my opionion... cleaner...

I just think the memphis has really changed over the last year or so, and maybe they cut costs somewhere, resulting in the amps picking up interference... (like from the fuel pump maybe, or anything...)

and about the fuse thing... I can't believe anyone would recommend that... because then the amp could easily burn up, right? it seems that you would just put in a bigger fuse instead...

edit: oh yeah, and scratch my earlier reference to the 1500D... I have no experience with that, and I have heard EXCELLENT things about it... I only had this year's 1605D
