I have a C5 convertible, I have upgraded front and rear speakers to Infinity's and made a nice difference and now I am looking to add a sub woofer and I have some amp questions. So far my research has led me to a JL Audio 250/1 and run the JL Audio 10" woofer. Would anyone recommend a different amp?

My main question is on the Phoenix Gold Octane-R 4.0:2 75W x 2, It says 250 watts RMS x 1 bridged output at 4 ohms, I understand what the 4 ohms are but what does the "bridged" mean, I am assuming it means it takes 2 sides (x 2) and makes them into one (x 1) and this would allow me to send 250 watts to the 10" woofer?

Thanks - amps are not my speciality..

you got it all right. just make sure your sub is a single voice coil 4 ohm sub or a dual voice coil (dvc) 2 ohm sub and you'll be ready to rock. check out image dynamics for some great subs that don't break the bank.

 

What exactly are your goals and budget. You dont need to spend JL money to get a good sounding setup

 

Just wanted something with a little more thump, I figured I would purchase some sort of stealth box, go with around a 10" woofer and try and match the amp to the woofer, around 250 watts is what I was thinking.

By the time I buy the Pac adapter, woofer, amp, and box, then purchase a terminal extender along with some wiring, I have it roughly figured at 5 to 6 hundred dollars, but I really didnt want to spend that much, anyone have other alternatives that could save some money but still end up with a nice thump, I would be all ears...

Thanks

Damnit I had a whole nice thing setup on here with prices and some how hit back on my browser and lost it and now im pissed and dont wanna retype it all haha.

Ok ultra budget but still nice little setup here we go

Box from corvettecaraudio.com (125+shipping) or build your own (30ish)

Sub - MA Audio 10" nice little sub and killer price, i did 4 of these in a honda accord and WOW (http://sonicelectronix.com/item_2674.html) free shipping (50 bucks )

Amp - profile refub has 1 year warranty I use alot of these when ppl dont necessarily need cream of the crop, i ran one of the older models for 3 yrs never had a problem (http://profilecaraudio.com/amplifiers.htm) 400msx would be about (60 shipped)

Wiring - knukonceptz eko 8ga kit (high quality kit) (25 shipped)

Pac adapter - 55ish on ebay

Total is under 350 dollars

If you build your own box u could save 100 dollars or so. Otherwise an infinity basslink or bazooka bass tube could add some bass but you start to get close to the price or the outlined system about and it wont sound half as good.

I just did the exact above setup in a Transam and the kid was very happy it pounds nicely.


Otherwise for about 100 dollars more you could step up to an Elemental Designs 13kv2 and a Phoneix Gold PG 5.0:1 mono block amp. Run about 400wrms and it would hit alot harder and be a lil bit tighter sounding.

 

pentavolvo, this is great information. I took my 2004 convertible to a local car audio shop and told them I wanted an amp/sub/box (to go in center cubby) and was quoted $1400 for a JL system incl. installation. I am looking for a low-budget amp/sub/box to boost my stock system. I don't really need a high end system. To be honest, not sure my ears would know the difference.

Is what you quoted all I will need? What is the PAC adapter? Assuming I don't DIY, which I'm not sure I want to tackle, what can I expect to pay for installation? Oh, and will the stock CD changer fit in a side cubby on the convertible?

 

Honestly i dont think the stock changer fits but I could be wrong. The pac adapter is a factory integration harness basically makes it plug and play into your radio. Install prly around 100. You can do this yourself its very user friendly install I can literally talk you through it all on the phone, or give u guidance, dont be intimidated by the vette its easier then most 15k dollar econo boxes to work on

That is all you would need though, if i recall you have top mount battery terminals, but if you have sidepost you need a sidepost adapter its like 5 dollars locally.

Check out this install writeup I did should give you the confidence you need. Literally you pull the center counsel and the passenger seat (its 4 bolts). Going into this blind it should take no more then 3 hours and thats taking extreme time, i have done em in under an hour more then once

Thanks again for the great information. I'm still hesitant about DIY, but you never know!!
