Sub Amp 4 channel deal :D

[time_to_ride]

Im thinkin of gettin this Sub amp deal (http://caraudiosecurity.com/shop/product/products_id/3352.html)but i think my HU only has 1 preout so i called CarAudioSecurity (www.caraudiosecurity.com) and they said they could do a deal where i paid the difference to upgrade from a 2 channel amp to a 4 channel

I think the old amp looks better, but im not sure about the performance of it?
I think its better but my knowledge is limited when it comes to Subs and Amps, can any1 help? there's only £10 difference in it :p

Infinity: REF-7541A - 4-channel Amplifier (http://caraudiosecurity.com/shop/product/products_id/4438.html)

or

Infinity: REF475a - 4-channel Amplifier (http://caraudiosecurity.com/shop/product/products_id/6695.html)

I'duse2 channels for my comps (http://caraudiosecurity.com/shop/product/products_id/6691.html). And i'll bridge the other 2 for a sub (is this called tri mode?)

Would all this go together?
Thanx

I'm trying to work out your problem, you are afraid that you only have 1 pre-out yet you are upgrading from an amp that only requires 1 pre-out to and amp that requires 2.

From what I can tell, were you planning on getting the original sub and amp deal with the intention of getting another amp to power your components in the future, hence 2 pre-outs in the end but you found out you only have 1 pre-out.

I take it you thought that you could get a 4 channel and run both the sub and components, but didn't realise that a 4 channel amp requires 2 rca cables, 1 for the sub and 1 for the comps, therefore the HU needs 2 pre-outs.

There is a way around this, you can buy RCA splitters that can enable you to use 2 pre-outs when a HU only has 1. Something along the lines of these, RCA Splitter (http://www.incarexpress.co.uk/view_product.php?partno=PC11F). Could be Male to Female or Vice Versa, depends what connectors are on your amp and head unit.

Sorry,

My HU only has 1 preout (I tihnk)

But instead of buying that exact deal im buying it with a 4 channel amp instead of a 2 channel?

I wont need 2 pre outs for 1 amp will I?

[CSVTR]

Unfortunatly yes, a 4 channel amp requires 2 pre-outs, it's the same as having 2 seperate 2 channel amps. But as I said before you can get splitters which enable you to gonnect 2 sets of RCA cables to 1 pre-out, and to answer your original question you may aswell get a 4 channel amp, less hassle than 2 amps. In my opinion the 1st 4 channel amp you mentioned is the better of the 2.

i replyed in the other thread mate

dont rate infinity stuff at all tbh also you can buy a y-phono lead which will split 1 set of phono leads into 2, only thing is it wont set up on the headunit that good and supposeably you lose sound quality, but never noticed it when i used it, you can however just adjust the amp to suit the speaker

Im just planning things out at the moment :D

Any more thoughts as to which amp?

thanx :y:

theres a really good jbl amp on offer at the moment, in tri mode it runs at 2 x 100 and 1 x 300 rms and for just over 60 quid you cant go wrong :y:
