Do you have specs for your amp? If so what’s the RMS @ 2 ohms X1 channel

Alternator upgrades depend on some certian factors. A) Are you going to buy a custom aftermarket alternator. B) Have the existing alternator rebuild.

Custom aftermarket alternator, usually those made by such companies like stinger & ohio generator will run you up in the high $100 range. I know for my 86 Dodge Ramcharger, I was looking at about $700 for a 160 amp alternator.  The upside to these alternators are that they're very relaible.  The downside, they'er gonna cost ya a lot of money

For a rebulid alternator, usually there cheaper because they just rebuild your current alternator to run at a higher ampage than before. The downside is that most alternator can't be rebuild to run higher because the housing may be to small to handle the extra coiling, then the life expectance of a rebuild alternator  is lessened becuase your having that alternator produce more power than what it was originally suppose to.  Again looking to have this done on my truck, but the alternator that's standard on my truck was too small to coil up to 160, so I had to have an alternator off a ford ambulance custom built with special bracing to mount it into the original amps postions. All in all I was looking at about $200 for the total job.

I haven't made my decision as to which way I'm gonna go for now, but I do know  that I will most likely go towards the aftermarket alternator in the future cause I plan on rebuilding the whole engine, but as of right now I think I'm gonna go with the rebuild one. Just because I know that I'll be able to have the extra head room now, without having to spend over a half a grand that I don't have.

If I were you, I would shop around to local audio shops, and machine shops that work on alternator. Who knows what kind of deals you could come up with.

live & die 4 tha luv of BASS!!!!

US acoustics,

I have heard  good things about this amp. I would try it out first at the 20hm load to see how it sounds.  But if you have the money, I would look at amps from such brands as, MTX, JL Audio, JBL, Xant, Kicker, and DEI. But be warned, the high powered mono block digital amp form any of these companies will cost ya a lot of cash.

yeah well im still debating on what to do.

so far i know that im gonna swtich the system and get 1 Kicker  S12L7 in a sealed box around 1 cuft. next im gonna change my 1 farad capr to a 2farad cap. my amp pushed the 2 audiobahns now but like i said sometimes they crap out and i dont liike that. i want good hard hitting clean bass..

the best way to somewhat describe what i want is if you ever heard the fosgate xterra. i heard it once and i almost creamed my pants. it was hitting so hard but you didnt heard the subs hitting like normal but you sure felt it. i dont know if you understand what i mean but thats somewhat the way i want it . i knowit wont be exactly like it but i would like to try for it a litle. please let me know what you guys think . if u think my amp can handle it ill try it first but if it cant i avent decided on an amp yet

 thanks for your help.

As far as the US800d I would try it and if you feel like you can get more out of the sub then change out the amp. For alternators the following are all good sites. I have experience with the following companies and can say that I have never had a problem with any of there alternators and they cost much less then those big names.

The amp can barely push the 12 it will push the 15 but the power will not be clean and you will not get its full potential. With the 15 you will loose some sq but it will put out lower deep bass that you will feel. If you’re considering the 15 then go for it because if you get the 12 then all you’re going to think about is that 15 and what it would have sounded like. Look if you have too much bass you can always turn it down but it doesn’t work the other way around. My suggestion to you would be to go to a shop that has the 12 and the 15 and listen to them both and see which one sounds best to you.
