Memphis products - Toyota Nation Forum : Toyota Car and Truck Forums

Well I've been reading stuff around here for a year and some months, but low and behold I never noticed the audio forum. Anyhow, I put together a humble system in my 1996 Camry DX a few months ago. It's all 100% Memphis. But I don't see much if anything about Memphis products around here, so I wondered how they rate in yall's opinions.

First let me state that I'm an SPL kind of person. I've never heard a good SQ sub compared to a good SPL sub, so I have no idea what the differences are, but to me if it's loud, I'll probably like it.

Anyways, I'm running 2 Memphis HPO 12''s (the 85oz magnet ones). In a center ported 3/4 inch thick MDF box. Amplifier is a Memphis PR500.1 Class D. Head unit is a Pioneer P770 I got off ebay, and so far I've had good luck with it, works great. And I've got some Memphis PR 6.5s in the doors. Rear deck speakers are unplugged cause I don't really like them anyways. (pics below)

I'm pretty happy with everything. The subs rattle the little C A M R Y panel on my trunk like a bitch, that's my only complaint. But I'm not stuck on Memphis. Are there any SPL brands you guys consider to be of higher quality? Also, my Memphis amp blew 2 days ago, and I was thinking of upgrading it to a Memphis 1000.1 class D amp, would that be a wise course of action? The upgrade would only be $70 for me.

Just wondering yall's thoughts. Thanks.

memphis makes good stuff
as far as getting the 1000D...go for it...

if you like loud, you will want that kind of power
you will have to be careful not to rip those subs apart with that amp tho
arnt those subs about 400 watts rms apiece ??

Memphis ain't bad. A little bit overpriced imo. But pretty good stuff. Their amps are very compact which is nice.

If your subs are 400 watts rms each, and your amp does 1,000 watts rms, you'll be ok.

Actually, I think memphis rated them at 300 - 350 RMS. Is that still okay?

Oh and a quick question.

If you have a 500 watt amp that can already push a set of subs to the point of distortion, what will adding more power do really? I don't really understand that whole aspect.

You probably have the gain set too high(hence the blown amp)

By adding more power, you'll be able to keep the gain lower, and you'll get less distortion by sending clean unclipped power to the subs.

Actually, the amp blew almost immediately after I turned the gain DOWN. It blew at a 10 o' clock gain setting. With bass boost at 0 DB.

I think, and I could be wrong, but 10 o'clock on your amps gain is near max setting.

Got a pic of your amps gain controls? Alot of amps are different.

cupcakes · 10-13-2005, 12:06 AM

Yeah here...

This was a pic before I turned the gain down. It WAS at 1 o' clock, and I turned it down to the nifty simulated red dot (10 o' clock). Sorry for the bad quality, but I had to jack the contrast on it way up, then compress it.

That's weird then. How soon after you adjusted it did it go out?

More lead way, reserve capacity, etc...

I say its always better to have more power then you need. Instead of not having enough power and pushing your amp to the point that it clips.

Since you have 2 subs, the 500W is split. IE: 250W to each sub.

cupcakes · 10-13-2005, 09:34 AM

Yeah, makes sense. Um, literally it was 5 minutes after I adjusted it (turned gain down and bass EQ to 7 o' clock) that it just quit working. Now power light, protect mode light isn't on, nothing. Fuses are fine.

grounds?

cupcakes · 10-13-2005, 01:18 PM

As far as I know the amp is nicely grounded to the steal part of the rear seat floor. But that didn't really cross my mind...I'll check after I get off work to see if the wire is still connected to the car's frame like it should be. Thanks for the idea.

If the power light isn't on, then it's probably the grounds or power wire or the turn on remote lead. Double check those. Also check at the battery and any other conecting point.

Guess it was just a bad amp. I re-traced every wire of the system, and they're all where they need to be without any holes, pinches or disconnects.
