some local guy is selling his amp and 2 10"subs for 420. He claimed that they have been used for a year, with receipts. I am wondering if i should get them instead of spending 700 on a brand new amp, 2 subs and wires. if you were me, which one would you be getting, considering the value and sound quality
ok here is the amp he is selling
Alpine MRV-T757(2 channel)
Max 750x1
75x2 rms cont.
150x2 rms cont 4ohm
240x1 rms cont

this is amp i wanna get
Alpine ClassD MRD-m500 (mono)
900x1 max
400x1 rms 2ohm
200x1 rms 4ohm

P.S either one will be powering 2 10" subs with 300w rms

What subs are you getting with it?

if i decide to buy the m500 from the store, i will trade in my currect 10" for 2 10". They are the same subs, except that the cones are different and mine is not dual voice coil
ALpine type r

If you are willing to wait a month or so, I can get you the Alpine MRD-M500 and two Type-R SWR-1021D 10" dual 2ohm woofers for cheap. The reason for the dual 2ohms is, you would wire them in series to get a 4ohm sub each, and parallel them to the amp to get a 2ohm load on the amp. Send me an IM or a PM

just curious why to wait a month ? i thought i need 4ohm instead of 2ohm?

used stuff...is well, used. you dont really know for sure how they were treated or used. or even hooked up correctly.

if you can afford it, get it new.

I have to order them from Alpine and they take 4-6 weeks to ship me the stuff.

Most amps run most efficiently at 2ohms. The alpine amp you wanted to get gives 400watts RMS @ 2ohms, but only 200watts RMS @ 4ohms. PM/IM me if you have any more questions. :thumbup:

i assumed it's not all about power, i chose 4ohms subs cuz i want the final output to be 4ohms...i don't know what im saying. anyone?

Cashis EG8

Having a final output of 4ohms would be good if you were using a 2 channel amp because then you could run it at 4ohm bridged (effectively a "2 ohm" load, but I won't get into that). Since the amp you are getting is a 1 channel mono amp, you can't bridge it. Therefore it runs most efficiently when shown a 2ohm load. Theres some website that explains all this in detail. Anybody know the site?

I just bought my friend friend's system for $850. 2 Phoenix Gold amps ( ZX600 and ZX475) and 2 10" JL W3 D4's. Buying a used stuff is not really bad because you're saving money but if you can check it then that's good. I ask the guy to play the subs first before I buy it and he did. I even helped him uninstall the system out of his car. Right now i'm saving money to have a custom made box for my 01 accord 4 dr. Check it first before buying if you can.
