Amp underpowering my subs ?
 

First of all i'd like to say hello to everyone on these forums and introduce myself. i just got into car audio about a year back and have recently been making some upgrades... here's some questions.

When i first started off i got some stuff from walmart.. which i'm slowly regretting and getting rid off, i just purchased a brand new alpine CDE 9874 deck.
Now i got an alpine MRP M350 powering 2 subs, 1 sony xplod 1200 watt ( rated at about 350 RMS ) and one Pioneer 800 ( 150 RMS ) both of these come from walmart i'm pretty sure.

Specs on my amp :

RMS Power Output (Watts x Channels) 200 x 1

Peak Power Output (Watts x Channels) 700 x 1
Power at 2 Ohms (Watts x Channels) 350 x 1

It says hook up a second sub get 400 watts, not sure how that works.

Anyways i think my amp is either underpowering my subs seeing as my bass is distorted when cranked or my subs are just garbage.

I used to have just the Pioneer sub running from my other amp which is a DUAL amp also from walmart.. which now does a good job in powering my speakers and actually had better bass then than it does now when 2 subs are hooked up to my alpine.

Could anyone help me or tell me what i could do/change.

Personally i am thinking of getting rid of my subs + alpine amp and upgrading to 2 10" Alpine Type S subs and getting an alpine MRP M500.

Any ideas would be welcome, thanks.

what kind of subs??

Sorry i forgot to mention that, both are 12" subs and are in a dual box with seperate chambers, believe they're 4 ohm's stable.
I actually have no clue on the Ohm's part, all i know is my Alpine amp has a + and a - and there's 2 postives and 2 negatives running, one pair to each sub.

what brand of subs and what model. its gonna help alot if i know this first lol

12" Sony Xplod 1200 Watt PEAK 350 RMS
12" Pioneer TS-W302R 800 PEAK 50-150 RMS

Both are 4 Ohm subs

are you using those 2 subs in the same box at the same time on one amp?????

if you are connecting both subs to the same amp then yes you are underpowering it by 125watts rms approx. even then your subs dont match so its gonna sound horrible anyway lol

Yup they are running in a custom built box, at the same time and they each have a seperate chamber. running off of one amp, the alpine MRP M350

Yeah i agree with you Dany, they do sound horrible and distorted when i crank it..
I will get rid of them tomorrow or so, gonna get some Alpine Type S subs with a MRP M500 mono amp.
This should sound a little bit better i hope.

Any other advice ? any other brands i should look at besides alpine ?

what does your town offer??? check all shops around there and demo some with your own music. whats your budget???
