Alright guys, I was just looking for a little bass.. What I have/had

Amp: Sony XM-1252GTR 800watt max;
https://www.crutchfield.com/S-MDHFA2I...M-1252GTR.html

Sub: MA Audio MA100QS 10inch Sub;
https://www.sonicelctrnix.com/item_...o+MA100QS.html

It all worked pretty good For a long time till I decided to turn the amp up a bit.. Now it keeps cutting out, but the AMP is powered on. The correct wiring was done,and the wires are all the correct wires for this set up.. So I assume its my Sub, which is no big deal because I got it dirt cheap new on EBAY.

I dont know anything about the 3 settings on the AMP..

There is LEVEL. What should it be set at so that I dont blow my sub?

Low Boost.. What should this be?

And then there is Filter(8ohm) with 3 options.. LP, off, and HP.. what should it be set at?

And also, Im going to use this same Amp because I have it and dont want to spend much money.. Anyone reccomend a good 10 inch Sub that would work well with my amp? I dont want anything super loud, just some nice sounding bass.. Dont want to spend too much. I will probably just buy the same MA audio sub unless you guys dont think its good, or dont think it works well with my amp

Sorry for all the "noob" questions but I really want to get it all squared away so I dont have to keep messing with it and getting in the truck of my Mint Integra. very annoying.

https://www.the12volt.com/installbay/forum_posts.asp~TID~85479~PN~1 Use this as your guide for setting the gain/level

You are running the amp on subs so you want the LP(low pass filter) this will filter out the higher frequancies that the sub cannnot or has trouble reproducing.

the low boost is a bass boost to gain level in a certain LP freq range. Basically like a loud button on a radio. You will use this like the gain but it will effect just a certain frequancy. also like the gain setting you will want to not give it too much or you will create excess distortion and run the risk of running the amp into clipping.

OK guys, I purchased an Alpine Sub.. Its a Single Voice Coil 4 ohm Sub.. My Amp is a 2 channel Amp. I want to make sure I hook it up right. The Amp has 2 posotive hook ups, and 2 negative hook ups.

Once the wires are hooked up to my sub, Which set of hook ups do I run them to? Lets say on the Amp, that there is a set of positve and negative hook ups on the left, and another set on the right.. My question is, Do I take the positive wire from my sub and hook it up on the left, AND take the Negative wire from my sub and hook it up on the right? Or Do i Hook up the positive on the Rightside positive, and the negative on the left side negative.. Does my Question make sense?

you can safley bridge the amp with that sub. There probably is marking of some sort showing what positive and negetive to use to do this. It should be a positive from one channel and negetive from the other channel(mat have a line from one of the positives to the negetive you need to use.). this will only work as low as a 4ohm load on that amp so with just the one single 4 it will work perfectly with 314 rms to the sub. As for which positive an neg i would not know unless i looked at the amp. I am not familiar with that amp but, I did look up the specs and it clearly shows it is bridgable at 4ohm.
